Animal science is described as "studying the biology of animals that are under the control of humankind". It can also be described as the production and management of farm animals. Historically, the degree was called animal husbandry and the animals studied were livestock species, like cattle , sheep , pigs , poultry , and horses . Today, courses available look at a broader area, including companion animals, like dogs and cats , and many exotic species. Degrees in Animal Science are offered at a number of colleges and universities. Animal science degrees are often offered at land-grant universities, which will often have on-campus farms to give students hands-on experience with livestock animals.
59-441: Professional education in animal science prepares students for careers in areas such as animal breeding, food and fiber production, nutrition, animal agribusiness , animal behavior, and welfare. Courses in a typical Animal Science program may include genetics, microbiology, animal behavior, nutrition, physiology, and reproduction. Courses in support areas, such as genetics, soils, agricultural economics and marketing, legal aspects, and
118-765: A Master of Science degree option, students take required courses in areas that support their main interest. These courses are above courses normally required for a Bachelor of Science degree in the Animal Science major. For example, in a Ph.D. degree program students take courses related to their major that are more in-depth than those for the Master of Science degree, with an emphasis on research or teaching. Graduate studies in animal sciences are considered preparation for upper-level positions in production, management, education, research, or agri-services. Professional study in veterinary medicine, law, and business administration are among

Therefore, the manufacturing process leaves few characteristics distinctive of the natural source material in the finished products. Some examples of this fiber type are: Historically, cellulose diacetate and -triacetate were classified under the term rayon, but are now considered distinct materials. Synthetic come entirely from synthetic materials such as petrochemicals , unlike those artificial fibers derived from such natural substances as cellulose or protein. Fiber classification in reinforced plastics falls into two classes: (i) short fibers, also known as discontinuous fibers, with
767-634: A woven, non woven or knitted structure. Fiber surfaces can also be dull or bright. Dull surfaces reflect more light while bright tends to transmit light and make the fiber more transparent. Very short and/or irregular fibers have been called fibrils. Natural cellulose , such as cotton or bleached kraft , show smaller fibrils jutting out and away from the main fiber structure. Fibers can be divided into natural and artificial (synthetic) substance, their properties can affect their performance in many applications. Synthetic fiber materials are increasingly replacing other conventional materials like glass and wood in

A fertilizer ( American English ) or fertiliser ( British English ) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients . Fertilizers may be distinct from liming materials or other non-nutrient soil amendments . Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in
