Lepe is a Spanish town in the province of Huelva , in the autonomous community of Andalusia . It is near the Portuguese border. According to the 2022 census , the city has a population of 28,617 inhabitants.
112-415: Until the late 1970s its economy was based on fishing but Lepe is now one of the wealthiest villages in the region thanks to its intensive farming of strawberries, which are exported all over Europe. Lepe is known for its strawberries , and for Spanish jokes referring to its inhabitants as stupid. Although deposits of Neolithic and Bronze Age have been found, there is no evidence of stable settlements in
224-455: A phytohormone involved in regulating stem growth via its effect on cell division. Photosynthate investment in the stem is reduced dramatically in shorter plants and nutrients become redirected to grain production, amplifying in particular the yield effect of chemical fertilizers. High-yielding varieties outperformed traditional varieties several fold and responded better to the addition of irrigation, pesticides, and fertilizers. Hybrid vigour
336-407: A terrace is a leveled section of a hilly cultivated area, designed as a method of soil conservation to slow or prevent the rapid surface runoff of irrigation water. Often such land is formed into multiple terraces, giving a stepped appearance. The human landscapes of rice cultivation in terraces that follow the natural contours of the escarpments, like contour ploughing , are a classic feature of

Many urban children experience animal husbandry for the first time at a petting farm ; in Britain, some five million people a year visit a farm of some kind. This presents some risk of infection , especially if children handle animals and then fail to wash their hands ; a strain of E. coli infected 93 people who had visited
560-446: A fertiliser, returning minerals and organic matter to the soil in a semi-closed organic system. Although all mammals produce milk to nourish their young, the cow is predominantly used throughout the world to produce milk and milk products for human consumption. Other animals used to a lesser extent for this purpose include sheep, goats, camels, buffaloes, yaks, reindeer, horses and donkeys. All these animals have been domesticated over
672-584: A long history, starting with the Neolithic Revolution when animals were first domesticated , from around 13,000 BC onwards, predating farming of the first crops . During the period of ancient societies like ancient Egypt , cattle , sheep , goats , and pigs were being raised on farms. Major changes took place in the Columbian exchange , when Old World livestock were brought to the New World, and then in
784-606: A much more equal and controlled distribution pattern. Drip irrigation is the most expensive and least-used type, but delivers water to plant roots with minimal losses. Water catchment management measures include recharge pits, which capture rainwater and runoff and use it to recharge groundwater supplies. This helps in the replenishment of groundwater wells and eventually reduces soil erosion. Dammed rivers creating reservoirs store water for irrigation and other uses over large areas. Smaller areas sometimes use irrigation ponds or groundwater. In agriculture, systematic weed management
896-476: A paddock, while allowing the others to recover. Resting grazed lands allows the vegetation to renew energy reserves, rebuild shoot systems, and deepen root systems, resulting in long-term maximum biomass production. Pasture systems alone can allow grazers to meet their energy requirements, but rotational grazing is especially effective because grazers thrive on the more tender younger plant stems. Parasites are also left behind to die off, minimizing or eliminating
1008-487: A plough to increase production of crops, and drawing a sledge, and later a cart, to bring the produce home from the field. Draught animals were first used about 4,000 BC in the Middle East, increasing agricultural production immeasurably. In southern Asia, the elephant was domesticated by 6,000 BC. Fossilised chicken bones dated to 5040 BC have been found in northeastern China, far from where their wild ancestors lived in
1120-521: A regional or national scale, and the functioning of agro-ecosystems has been profoundly altered. Agricultural intensification includes a variety of factors, including the loss of landscape elements, increased farm and field sizes, and increase usage of insecticides and herbicides. The large scale of insecticides and herbicides lead to the rapid developing resistance among pests renders herbicides and insecticides increasingly ineffective. Agrochemicals have may be involved in colony collapse disorder , in which
1232-433: A relatively small area of land, for example by rotational grazing , or sometimes as concentrated animal feeding operations . These methods increase the yields of food and fiber per unit land area compared to those of extensive animal husbandry ; concentrated feed is brought to seldom-moved animals, or, with rotational grazing, the animals are repeatedly moved to fresh forage. Agricultural development in Britain between

#17328591901751344-562: A significant impact on the world environment. Both production and consumption of animal products have increased rapidly. Since 1950, meat production has tripled, whereas the production of dairy products doubled and that of eggs almost increased fourfold. Meanwhile, meat consumption has nearly doubled worldwide. Developing countries had a surge in meat consumption, particularly of monogastric livestock. Animal husbandry drives climate change, ocean acidification, and biodiversity loss, and kills 60 billion animals annually. It uses between 20 and 33% of
1456-816: A small area and given supplementary heating. Litter on the floor absorbs the droppings and the area occupied is expanded as they grow. Feed and water is supplied automatically and the lighting is controlled. The birds may be harvested on several occasions or the whole shed may be cleared at one time. A similar rearing system is usually used for turkeys, which are less hardy than chickens, but they take longer to grow and are often moved on to separate fattening units to finish. Ducks are particularly popular in Asia and Australia and can be killed at seven weeks under commercial conditions. Aquaculture has been defined as "the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants and implies some form of intervention in
1568-462: A small space poses ethical issues to some consumers. Animal rights and animal welfare activists have charged that intensive animal rearing is cruel to animals. The Green Revolution transformed farming in many developing countries. It spread technologies that had already existed, but had not been widely used outside of industrialized nations. These technologies included "miracle seeds", pesticides, irrigation, and synthetic nitrogen fertilizer. In
1680-539: A typical broiler chicken at eight weeks old was 4.8 times as heavy as a bird of similar age in 1957, while in the thirty years to 2007, the average milk yield of a dairy cow in the United States nearly doubled. Good husbandry, proper feeding, and hygiene are the main contributors to animal health on the farm, bringing economic benefits through maximised production. When, despite these precautions, animals still become sick, they are treated with veterinary medicines , by
1792-550: A week. At the other extreme, in the more developed parts of the world, animals are often intensively managed ; dairy cows may be kept in zero-grazing conditions with all their forage brought to them; beef cattle may be kept in high density feedlots ; pigs may be housed in climate-controlled buildings and never go outdoors; poultry may be reared in barns and kept in cages as laying birds under lighting-controlled conditions. In between these two extremes are semi-intensive, often family-run farms where livestock graze outside for much of

Most production of silk occurs in the Far East, with a synthetic diet being used to rear the silkworms in Japan. Insects form part of the human diet in many cultures. In Thailand, crickets are farmed for this purpose in the north of the country, and palm weevil larvae in
2016-532: Is a progressive, sustainable agriculture system such as zero waste agriculture or integrated multi-trophic aquaculture , which involves the interactions of multiple species. Elements of this integration can include: Industrial agriculture uses huge amounts of water , energy , and industrial chemicals , increasing pollution in the arable land , usable water , and atmosphere . Herbicides , insecticides , and fertilizers accumulate in ground and surface waters . Industrial agricultural practices are one of
2128-475: Is a type of agriculture , both of crop plants and of animals , with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital , labour , agrochemicals and water, and higher crop yields per unit land area. Most commercial agriculture is intensive in one or more ways. Forms that rely heavily on industrial methods are often called industrial agriculture , which
2240-593: Is characterized by technologies designed to increase yield. Techniques include planting multiple crops per year, reducing the frequency of fallow years, improving cultivars , mechanised agriculture , controlled by increased and more detailed analysis of growing conditions, including weather, soil , water, weeds, and pests. Modern methods frequently involve increased use of non-biotic inputs, such as fertilizers , plant growth regulators, pesticides , and antibiotics for livestock. Intensive farms are widespread in developed nations and increasingly prevalent worldwide. Most of
2352-432: Is continuously cropped. Crop rotation also seeks to balance the nutrient demands of various crops to avoid soil nutrient depletion. A traditional component of crop rotation is the replenishment of nitrogen through the use of legumes and green manure in sequence with cereals and other crops. Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. A related technique

#17328591901752464-483: Is destroyed by clearing forests and converting land to grow feed crops and for grazing, while predators and herbivores are frequently targeted because of a perceived threat to livestock profits; for example, animal husbandry causes up to 91% of the deforestation in the Amazon region . In addition, livestock produce greenhouse gases . Cows produce some 570 million cubic metres of methane per day, that accounts for 35 to 40% of
2576-632: Is hostile to many species of weeds . As the only draft animal species which is comfortable in wetlands , the water buffalo is in widespread use in Asian rice paddies. A recent development in the intensive production of rice is the System of Rice Intensification . Developed in 1983 by the French Jesuit Father Henri de Laulanié in Madagascar , by 2013 the number of smallholder farmers using

Pigs and poultry are non-ruminants and unable to digest the cellulose in grass and other forages, so they are fed entirely on cereals and other high-energy foodstuffs. The ingredients for
2800-455: Is managed by farmers with a view to encouraging traits seen as desirable. These include hardiness, fertility, docility, mothering abilities, fast growth rates, low feed consumption per unit of growth, better body proportions, higher yields, and better fibre qualities. Undesirable traits such as health defects and aggressiveness are selected against. Selective breeding has been responsible for large increases in productivity. For example, in 2007,
2912-456: Is no single universally agreed definition of which species are livestock. Widely agreed types of livestock include cattle for beef and dairy, sheep, goats, pigs, and poultry. Various other species are sometimes considered livestock, such as horses, while poultry birds are sometimes excluded. In some parts of the world, livestock includes species such as buffalo, and the South American camelids,
3024-467: Is now frowned on in many countries because of the risk that it may lead to antimicrobial resistance in livestock and in humans. Governments are concerned with zoonoses , diseases that humans may acquire from animals. Wild animal populations may harbour diseases that can affect domestic animals which may acquire them as a result of insufficient biosecurity . An outbreak of Nipah virus in Malaysia in 1999
3136-441: Is often increased, yields of any single crop often decrease. There are also challenges to farmers who rely on farming equipment optimized for monoculture , often resulting in increased labor inputs. Vertical farming is intensive crop production on a large scale in urban centers, in multi-story, artificially-lit structures, for the production of low-calorie foods like herbs, microgreens , and lettuce. An integrated farming system
3248-461: Is only part of the purpose of keeping an animal which may also be used as a beast of burden or to draw a plough, or for the production of fibre, meat and leather, with the dung being used for fuel or for the improvement of soil fertility . Sheep and goats may be favoured for dairy production in climates and conditions that do not suit dairy cows. Meat , mainly from farmed animals, is a major source of dietary protein and essential nutrients around
3360-582: Is practical and down to earth, and anti-intellectual. Farm animals are widespread in books and songs for children; the reality of animal husbandry is often distorted, softened, or idealized, giving children an almost entirely fictitious account of farm life. The books often depict happy animals free to roam in attractive countryside, a picture completely at odds with the realities of the impersonal, mechanized activities involved in modern intensive farming . Pigs, for example, appear in several of Beatrix Potter 's "little books", as Piglet in A.A. Milne 's Winnie
3472-538: Is seasonal, for example in the temperate summer or tropical rainy season , so some areas of the crop are set aside to be cut and preserved, either as hay (dried grass), or as silage (fermented grass). Other forage crops are also grown and many of these, as well as crop residues, can be ensiled to fill the gap in the nutritional needs of livestock in the lean season. Extensively reared animals may subsist entirely on forage, but more intensively kept livestock will require energy and protein-rich foods in addition. Energy

3696-556: Is the concentration of livestock in a given space. The aim is to provide maximum output at the lowest possible cost and with the greatest level of food safety. The term is often used pejoratively. CAFOs have dramatically increased the production of food from animal husbandry worldwide, both in terms of total food produced and efficiency. Food and water is delivered to the animals, and therapeutic use of antimicrobial agents, vitamin supplements, and growth hormones are often employed. Growth hormones are not used on chickens nor on any animal in
3808-770: Is the improvement of pasture soils and grasses to increase the food production potential of livestock systems. It is commonly used to reverse pasture degradation , a process characterized by loss of forage and decreased animal carrying capacity which results from overgrazing , poor nutrient management , and lack of soil conservation . This degradation leads to poor pasture soils with decreased fertility and water availability and increased rates of erosion, compaction, and acidification . Degraded pastures have significantly lower productivity and higher carbon footprints compared to intensified pastures. Management practices which improve soil health and consequently grass productivity include irrigation , soil scarification, and
3920-411: Is the modern method to minimize pesticide use to more sustainable levels. There are concerns over the sustainability of industrial agriculture, and the environmental effects of fertilizers and pesticides, which has given rise to the organic movement and has built a market for sustainable intensive farming, as well as funding for the development of appropriate technology . Pasture intensification
4032-493: Is to plant multi-species cover crops between commercial crops. This combines the advantages of intensive farming with continuous cover and polyculture . Crop irrigation accounts for 70% of the world's fresh water use. Flood irrigation , the oldest and most common type, is typically unevenly distributed, as parts of a field may receive excess water in order to deliver sufficient quantities to other parts. Overhead irrigation , using center-pivot or lateral-moving sprinklers, gives
4144-426: Is usually required, often performed by machines such as cultivators or liquid herbicide sprayers. Herbicides kill specific targets while leaving the crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often based on plant hormones . Weed control through herbicide is made more difficult when the weeds become resistant to the herbicide. Solutions include: In agriculture ,
4256-527: Is utilized in many important crops to greatly increase yields for farmers. However, the advantage is lost for the progeny of the F1 hybrids , meaning seeds for annual crops need to be purchased every season, thus increasing costs and profits for farmers. Crop rotation or crop sequencing is the practice of growing a series of dissimilar types of crops in the same space in sequential seasons for benefits such as avoiding pathogen and pest buildup that occurs when one species
4368-920: Is widespread. Modern animal husbandry relies on production systems adapted to the type of land available. Subsistence farming is being superseded by intensive animal farming in the more developed parts of the world, where, for example, beef cattle are kept in high-density feedlots , and thousands of chickens may be raised in broiler houses or batteries . On poorer soil, such as in uplands, animals are often kept more extensively and may be allowed to roam widely, foraging for themselves. Animal agriculture at modern scale drives climate change , ocean acidification , and biodiversity loss . Most livestock are herbivores , except for pigs and chickens which are omnivores . Ruminants like cattle and sheep are adapted to feed on grass; they can forage outdoors or may be fed entirely or in part on rations richer in energy and protein, such as pelleted cereals. Pigs and poultry cannot digest

4816-985: The carbon balance is the use of integrated crop-livestock (ICL) and crop-livestock-forestry (ICLF) systems, which combine several ecosystems into one optimized agricultural framework. Correctly performed, such production systems are able to create synergies potentially providing benefits to pastures through optimal plant usage, improved feed and fattening rates, increased soil fertility and quality, intensified nutrient cycling , integrated pest control , and improved biodiversity . The introduction of certain legume crops to pastures can increase carbon accumulation and nitrogen fixation in soils, while their digestibility helps animal fattening and reduces methane emissions from enteric fermentation . ICLF systems yield beef cattle productivity up to ten times that of degraded pastures; additional crop production from maize , sorghum , and soybean harvests; and greatly reduced greenhouse gas balances due to forest carbon sequestration. In

The verb to husband , meaning "to manage carefully", derives from an older meaning of husband , which in the 14th century referred to the ownership and care of a household or farm, but today means the "control or judicious use of resources", and in agriculture, the cultivation of plants or animals. Farmers and ranchers who raise livestock are considered to practice animal husbandry . The domestication of livestock

Half-wild dogs, perhaps starting with young individuals, may have been tolerated as scavengers and killers of vermin, and being naturally pack hunters , were predisposed to become part of the human pack and join in the hunt. Prey animals, sheep, goats, pigs and cattle, were progressively domesticated early in

Lagoons not protected with an impermeable liner can leak into groundwater under some conditions, as can runoff from manure used as fertilizer. A lagoon that burst in 1995 released 25 million gallons of nitrous sludge in North Carolina's New River . The spill allegedly killed eight to ten million fish. The large concentration of animals, animal waste, and dead animals in

This in turn contributed to unprecedented population growth, freeing up a significant percentage of the workforce, and thereby helped enable the Industrial Revolution . Historians cited enclosure , mechanization , four-field crop rotation , and selective breeding as the most important innovations. Industrial agriculture arose in

In the developed world, the majority of the poultry reared for meat is raised indoors in big sheds, with automated equipment under environmentally controlled conditions. Chickens raised in this way are known as broilers, and genetic improvements have meant that they can be grown to slaughter weight within six or seven weeks of hatching. Newly hatched chicks are restricted to

In 1892, the first gasoline-powered tractor was successfully developed, and in 1923, the International Harvester Farmall tractor became the first all-purpose tractor, marking an inflection point in the replacement of draft animals with machines. Mechanical harvesters ( combines ), planters, transplanters, and other equipment were then developed, further revolutionizing agriculture. These inventions increased yields and allowed individual farmers to manage increasingly large farms.

The discovery of vitamins and their role in nutrition , in the first two decades of the 20th century, led to vitamin supplements, which in the 1920s allowed some livestock to be raised indoors, reducing their exposure to adverse natural elements. Following World War II synthetic fertilizer use increased rapidly. The discovery of antibiotics and vaccines facilitated raising livestock by reducing diseases. Developments in logistics and refrigeration as well as processing technology made long-distance distribution feasible. Integrated pest management
8400-444: The growing of crops for winter fodder gained ground. Peas, beans and vetches became common; they increased soil fertility through nitrogen fixation, allowing more livestock to be kept. Exploration and colonisation of North and South America resulted in the introduction into Europe of such crops as maize, potatoes, sweet potatoes and manioc, while the principal Old World livestock – cattle, horses, sheep and goats – were introduced into
8512-524: The history of agriculture. Pigs were domesticated in the Near East between 8,500 and 8000 BC, sheep and goats in or near the Fertile Crescent about 8,500 BC, and cattle from wild aurochs in the areas of modern Turkey and Pakistan around 8,500 BC. A cow was a great advantage to a villager as she produced more milk than her calf needed, and her strength could be put to use as a working animal , pulling
8624-466: The individual members of bee colonies disappear. (Agricultural production is highly dependent on bees to pollinate many varieties of fruits and vegetables.) Intensive farming creates conditions for parasite growth and transmission that are vastly different from what parasites encounter in natural host populations, potentially altering selection on a variety of traits such as life-history traits and virulence. Some recent epidemic outbreaks have highlighted
8736-409: The introduction of cage-cultured salmonids. As the virus spread from vertical transmission (parent to offspring) . Intensive monoculture increases the risk of failures due to pests , adverse weather and disease. A study for the U.S. Office of Technology Assessment concluded that regarding industrial agriculture, there is a "negative relationship between the trend toward increasing farm size and
8848-683: The island of Bali and the Banaue Rice Terraces in Banaue, Ifugao , Philippines . In Peru , the Inca made use of otherwise unusable slopes by building drystone walls to create terraces known as Andéns . A paddy field is a flooded parcel of arable land used for growing rice and other semiaquatic crops . Paddy fields are a typical feature of rice-growing countries of east and southeast Asia , including Malaysia, China, Sri Lanka, Myanmar, Thailand, Korea, Japan, Vietnam, Taiwan, Indonesia, India , and
8960-473: The jungles of tropical Asia, but archaeologists believe that the original purpose of domestication was for the sport of cockfighting . Meanwhile, in South America, the llama and the alpaca had been domesticated, probably before 3,000 BC, as beasts of burden and for their wool. Neither was strong enough to pull a plough which limited the development of agriculture in the New World. Horses occur naturally on
9072-530: The livestock known in ancient Egypt were available. In addition, rabbits were domesticated for food by the first century BC. To help flush them out from their burrows, the polecat was domesticated as the ferret , its use described by Pliny the Elder . In northern Europe, agriculture including animal husbandry went into decline when the Roman empire collapsed. Some aspects such as the herding of animals continued throughout
9184-585: The main drivers of global warming , accounting for 14–28% of net greenhouse gas emissions . Many of the negative effects of industrial agriculture may emerge at some distance from fields and farms. Nitrogen compounds from the Midwest, for example, travel down the Mississippi to degrade coastal fisheries in the Gulf of Mexico, causing so-called oceanic dead zones . Many wild plant and animal species have become extinct on
9296-490: The manufacture of synthetic fertilizers , further increasing crop yields . In 1909, the Haber-Bosch method to synthesize ammonium nitrate was first demonstrated. NPK fertilizers stimulated the first concerns about industrial agriculture, due to concerns that they came with side effects such as soil compaction , soil erosion , and declines in overall soil fertility , along with health concerns about toxic chemicals entering
9408-567: The meat, dairy products , eggs , fruits, and vegetables available in supermarkets are produced by such farms. Some intensive farms can use sustainable methods , although this typically necessitates higher inputs of labor or lower yields. Sustainably increasing agricultural productivity , especially on smallholdings , is an important way to decrease the amount of land needed for farming and slow and reverse environmental degradation caused by processes such as deforestation . Intensive animal farming involves large numbers of animals raised on
9520-510: The most widely held position in the western world, a form of utilitarianism : that it is morally acceptable for humans to use non-human animals, provided that no unnecessary suffering is caused, and that the benefits to humans outweigh the costs to the livestock. An opposing view is that animals have rights , should not be regarded as property, are not necessary to use, and should never be used by humans. Live export of animals has risen to meet increased global demand for livestock such as in
9632-534: The municipality of Lepe. During the initial period of Roman rule, Lepe there was a rustic villa. There were fish farms at the present location of Lepe, Valsequillo and El Terrón. The retreat of the coast caused the abandonment of the settlement of Valsequillo, while fishing by El Terrón has continued until today. It is during the heyday of Roman rule when it blooms Lepe settlement located in a small village, linked to farming their fields and fishing port of El Terron . Based on classical texts, several authors have identified
9744-566: The need for de-wormers. With the increased productivity of rotational systems, the animals may need less supplemental feed than in continuous grazing systems. Farmers can therefore increase stocking rates. Intensive livestock farming or "factory farming", is the process of raising livestock in confinement at high stocking density. " Concentrated animal feeding operations " (CAFO), or "intensive livestock operations", can hold large numbers (some up to hundreds of thousands) of cows, hogs, turkeys, or chickens, often indoors. The essence of such farms
9856-768: The need to plant cover crops after harvest . The pasture is intensively grazed both before and after grain production. This intensive system yields equivalent farmer profits (partly from increased livestock forage) while building new topsoil and sequestering up to 33 tons of CO 2 /ha/year. Biointensive agriculture focuses on maximizing efficiency such as per unit area, energy input and water input. Agroforestry combines agriculture and orchard/forestry technologies to create more integrated, diverse, productive, profitable, healthy and sustainable land-use systems. Intercropping can increase yields or reduce inputs and thus represents (potentially sustainable) agricultural intensification. However, while total yield per unit land area
9968-501: The overall methane emissions of the planet. Further, livestock production is responsible for 65% of all human-related emissions of nitrous oxide . Since the 18th century, people have become increasingly concerned about the welfare of farm animals . Possible measures of welfare include longevity , behavior , physiology , reproduction , freedom from disease , and freedom from immunosuppression . Standards and laws for animal welfare have been created worldwide, broadly in line with
10080-480: The parasite burdens of livestock results in increased productivity and profitability. Where the condition is serious, governments impose regulations on import and export, on the movement of stock, quarantine restrictions and the reporting of suspected cases. Vaccines are available against certain diseases, and antibiotics are widely used where appropriate. At one time, antibiotics were routinely added to certain compound foodstuffs to promote growth, but this practice
10192-406: The particular traits that suit their circumstances. Whereas in the past cows were kept in small herds on family farms , grazing pastures and being fed hay in winter, nowadays there is a trend towards larger herds, more intensive systems, the feeding of silage and "zero grazing", a system where grass is cut and brought to the cow, which is housed year-round. In many communities, milk production
10304-554: The period. By the 11th century, the economy had recovered and the countryside was again productive. The Domesday Book recorded every parcel of land and every animal in England: "there was not one single hide, nor a yard of land, nay, moreover ... not even an ox, nor a cow, nor a swine was there left, that was not set down in [the king's] writ." For example, the royal manor of Earley in Berkshire , one of thousands of villages recorded in
10416-410: The promotion of biodiversity . This strategy is declining in Europe today due to the intensification of agriculture. The mechanized and chemical methods used are causing biodiversity to decline. Traditionally, animal husbandry was part of the subsistence farmer's way of life, producing not only the food needed by the family but also the fuel, fertiliser, clothing, transport and draught power. Killing
10528-1033: The rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated." In practice it can take place in the sea or in freshwater, and be extensive or intensive. Whole bays, lakes or ponds may be devoted to aquaculture, or the farmed animal may be retained in cages (fish), artificial reefs , racks or strings (shellfish). Fish and prawns can be cultivated in rice paddies , either arriving naturally or being introduced, and both crops can be harvested together. Fish hatcheries provide larval and juvenile fish, crustaceans and shellfish, for use in aquaculture systems. When large enough these are transferred to growing-on tanks and sold to fish farms to reach harvest size. Some species that are commonly raised in hatcheries include shrimps , prawns , salmon , tilapia , oysters and scallops . Similar facilities can be used to raise species with conservation needs to be released into
10640-436: The social conditions in rural communities" on a "statistical level". Agricultural monoculture can entail social and economic risks. Animal husbandry Animal husbandry is the branch of agriculture concerned with animals that are raised for meat , fibre , milk , or other products. It includes day-to-day care, management, production, nutrition, selective breeding , and the raising of livestock . Husbandry has
10752-421: The south. The crickets are kept in pens, boxes or drawers and fed on commercial pelleted poultry food, while the palm weevil larvae live on cabbage palm and sago palm trees, which limits their production to areas where these trees grow. Another delicacy of this region is the bamboo caterpillar , and the best rearing and harvesting techniques in semi-natural habitats are being studied. Animal husbandry has
10864-755: The steppes of Central Asia and their domestication began around 3,000 BC in the Black Sea and Caspian Sea region. Although horses were originally seen as a source of meat, their use as pack animals and for riding followed. Around the same time, the wild ass was being tamed in Egypt. Camels were domesticated soon after this, with the Bactrian camel in Mongolia and the Arabian camel becoming beasts of burden. By 1000 BC, caravans of Arabian camels were linking India with Mesopotamia and
10976-408: The system had grown to between 4 and 5 million. Aquaculture is the cultivation of the natural products of water ( fish , shellfish , algae , seaweed , and other aquatic organisms). Intensive aquaculture takes place on land using tanks, ponds, or other controlled systems, or in the ocean, using cages. Intensive farming practices which are thought to be sustainable have been developed to slow
11088-539: The uplands of the United Kingdom, sheep are turned out on the fells in spring and graze the abundant mountain grasses untended, being brought to lower altitudes late in the year, with supplementary feeding being provided in winter. In rural locations, pigs and poultry can obtain much of their nutrition from scavenging, and in African communities, hens may live for months without being fed, and still produce one or two eggs
11200-603: The valleys. Animals can be kept extensively or intensively. Extensive systems involve animals roaming at will, or under the supervision of a herdsman, often for their protection from predators . Ranching in the Western United States involves large herds of cattle grazing widely over public and private lands. Similar cattle stations are found in South America, Australia and other places with large areas of land and low rainfall. Ranching systems have been used for sheep , deer , ostrich , emu , llama and alpaca . In
11312-487: The whole range of available plant material. Cattle, sheep, goats, deer and antelopes are ruminants ; they digest food in two steps, chewing and swallowing in the normal way, and then regurgitating the semidigested cud to chew it again and thus extract the maximum possible food value. The dietary needs of these animals is mostly met by eating grass. Grasses grow from the base of the leaf-blade, enabling it to thrive even when heavily grazed or cut. In many climates grass growth
11424-523: The wild long before that. Fixed comb hives are used in many parts of the world and are made from any locally available material. In more advanced economies, where modern strains of domestic bee have been selected for docility and productiveness, various designs of hive are used which enable the combs to be removed for processing and extraction of honey. Quite apart from the honey and wax they produce, honey bees are important pollinators of crops and wild plants, and in many places hives are transported around
11536-529: The wild, or game fish for restocking waterways. Important aspects of husbandry at these early stages include selection of breeding stock, control of water quality and nutrition. In the wild, there is a massive amount of mortality at the nursery stage; farmers seek to minimise this while at the same time maximising growth rates. Bees have been kept in hives since at least the First Dynasty of Egypt , five thousand years ago, and man had been harvesting honey from
11648-521: The world's fresh water, Livestock, and the production of feed for them, occupy about a third of the Earth's ice-free land. Livestock production contributes to species extinction , desertification , and habitat destruction . and is the primary driver of the Holocene extinction . Some 70% of the agricultural land and 30% of Earth's land surface is involved directly or indirectly in animal husbandry. Habitat
11760-495: The world's meat is produced from animals grazing on open ranges or on enclosed pastures, the other half being produced intensively in various factory-farming systems; these are mostly cows, pigs or poultry, and often reared indoors, typically at high densities. Poultry, kept for their eggs and for their meat, include chickens, turkeys, geese and ducks. The great majority of laying birds used for egg production are chickens. Methods for keeping layers range from free-range systems, where
11872-764: The world, averaging about 8% of man's energy intake. The actual types eaten depend on local preferences, availability, cost and other factors, with cattle, sheep, pigs and goats being the main species involved. Cattle generally produce a single offspring annually which takes more than a year to mature; sheep and goats often have twins and these are ready for slaughter in less than a year; pigs are more prolific, producing more than one litter of up to about 11 piglets each year. Horses, donkeys, deer, buffalo, llamas, alpacas, guanacos and vicunas are farmed for meat in various regions. Some desirable traits of animals raised for meat include fecundity, hardiness, fast growth rate, ease of management and high food conversion efficiency. About half of
11984-531: The year, silage or hay is made to cover the times of year when the grass stops growing, and fertiliser, feed, and other inputs are brought onto the farm from outside. Animals used as livestock are predominantly herbivorous , the main exceptions being the pig and the chicken which are omnivorous. The herbivores can be divided into "concentrate selectors" which selectively feed on seeds, fruits and highly nutritious young foliage, "grazers" which mainly feed on grass, and "intermediate feeders" which choose their diet from
12096-417: Was driven by the need to have food on hand when hunting was unproductive. The desirable characteristics of a domestic animal are that it should be useful to the domesticator, should be able to thrive in his or her company, should breed freely, and be easy to tend. Domestication was not a single event, but a process repeated at various periods in different places. Sheep and goats were the animals that accompanied
12208-455: Was enacted to protect and restore lakes and rivers to a "fishable, swimmable" quality. The United States Environmental Protection Agency identified certain animal feeding operations, along with many other types of industry, as "point source" groundwater polluters. These operations were subjected to regulation. In 17 states in the U.S., isolated cases of groundwater contamination were linked to CAFOs. The U.S. federal government acknowledges
12320-504: Was improved by Bakewell and in turn the Lincoln was used to develop the subsequent breed, named the New (or Dishley) Leicester. It was hornless and had a square, meaty body with straight top lines. These sheep were exported widely and have contributed to numerous modern breeds. Under his influence, English farmers began to breed cattle for use primarily as beef. Long-horned heifers were crossed with
12432-693: Was instrumental in developing wheat cultivars. IR8 , the first widely implemented high-yielding rice to be developed by the International Rice Research Institute , was created through a cross between an Indonesian variety named "Peta" and a Chinese variety named "Dee Geo Woo Gen". With the availability of molecular genetics in Arabidopsis and rice the mutant genes responsible ( reduced height (rht) , gibberellin insensitive (gai1) and slender rice (slr1) ) have been cloned and identified as cellular signalling components of gibberellic acid ,
12544-540: Was traced back to pigs becoming ill after contact with fruit-eating flying foxes , their faeces and urine. The pigs in turn passed the infection to humans. Avian flu H5N1 is present in wild bird populations and can be carried large distances by migrating birds. This virus is easily transmissible to domestic poultry, and to humans living in close proximity with them. Other infectious diseases affecting wild animals, farm animals and humans include rabies , leptospirosis , brucellosis , tuberculosis and trichinosis . There
