28-401: A cattle crush ), or they may become damaged during handling. In other circumstances, horned animals may be preferred, for example, to help the animal defend itself against predators , to allow the attachment of head yokes to draught oxen , to provide a hand-hold on smaller animals such as sheep, or for aesthetic reasons – in some breeds the retention of horns is required for showing . In

42-561: A consistent badger-faced color pattern was found and the California Variegated Mutant was born. Mr. Eidman bred sheep for over 15 years without selling off any stock. In 1982, Mr. Eidman's flock of 75 sheep were dispersed to many different buyers throughout the United States. Different farms had different breeding goals. Thus, only a handful of farms kept the breed pure, without crossing them to other sheep breeds. Today

56-463: Is different from Wikidata All article disambiguation pages All disambiguation pages Romeldale The Romeldale was developed in the early 1900s by A.T. Spencer, who crossed Romney rams which had been exhibited at the 1915 Panama-Pacific International Exposition with his flock of Rambouillet ewes. The breeding focused on producing soft, fine wool and good fleece weight, as well as medium to large market lambs for meat. Development of

70-409: Is discouraged as the polled locus is strongly associated with Polled Intersex Syndrome (PIS). Naturally polled water buffalo also have genital defects. Naturally polled animals may have scurs – small, loose, horny growths in the skin where their horns would be. In cattle, this trait has been traced to a separate gene (on a different chromosome ) from that responsible for polling. However,

84-872: The CVM standard may be registered as Romeldales. CVMs are all natural-colored sheep with a badger face pattern. Unusually for natural colored sheep, their fleece tends to darken with age rather than grow lighter. Both Romeldales and CVMs are polled . This sheep -related article is a stub . You can help Misplaced Pages by expanding it . Polled livestock Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded . Natural polling occurs in cattle , yaks , water buffalo , and goats , and in these animals it affects both sexes equally; in sheep , by contrast, both sexes may be horned, both polled, or only

98-464: The Romeldale continued throughout the 1940s and 50s, but a breed association for the original Romeldale alone was never formed and it is largely confined to its home state of California. Glen Eidman, during the 1960s, found a unique pattern in one of his Romeldale ewes. After subsequent breedings, the same pattern was found in one of his rams. After many attempts and selective breeding of the two sheep,

112-530: The Romeldale/CVM is still a very rare breed, and The Livestock Conservancy lists it as critical. The soft wool and the unusual colors of the CVM are especially prized by handspinners . Romeldales and CVMs are generally considered two types of the same breed. Other than color they share most of the same physical and temperamental traits, and are medium to large sheep at 150-275 pounds. The original Romeldales are mostly white, though any sheep not conforming to

126-757: The US no show requires horns to be left on. Most shows require at a minimum blunting of the horns to a minimum diameter of 1 ⁄ 2  inch. Boer Goat Shows allow disbudded goats. Dairy breeds of goats are required to be naturally hornless or disbudded. 4H and FFA show goats must be hornless or blunted so as not to be sharp and dangerous. Polled strains have been developed of many cattle breeds which were originally horned. This has usually been done by crossing with naturally polled breeds, most commonly Angus and Galloway cattle. For example, polled Jersey cattle originated in Ohio sometime prior to 1895. Two strains were developed,

140-400: The females polled. The history of breeding polled livestock starts about 6000 years BC. The archaic term muley or mulley is sometimes used to refer to hornless livestock (especially cattle) in folk songs , folk tales , and poetry , and in the name of the polled Irish Moiled cattle breed. "Muley" derives from Irish and Scottish Gaelic maol , and Welsh moel . In cattle ,

154-478: The first to appear being founded by crosses of registered Jersey bulls (the standard) on common muley (hornless) cows. These were graded up by the continued use of purebred Jersey sires, selection being made of the polled offspring of each generation, the horned progeny being discarded. Thus originated what was later known as the single-standard strain. As in the case of the Polled Shorthorns and Polled Herefords,

168-460: The polled allele is genetically dominant to that for horns. The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed to create polled versions of dairy breeds. In sheep , the allele for horns in both sexes is partially dominant to the allele for being polled in both sexes, and both of these are dominant to that for polling in the female only. The development of true breeding polled goats

182-477: The presence of the allele for scurs in cattle can only be seen in a polled animal, because horns replace the scurs in horned animals. Similar scurs may also occur where disbudding of a naturally horned animal has been incomplete. Polled livestock are preferred by many farmers for a variety of reasons, the foremost being that horns can pose a physical danger to humans, other livestock and equipment. Horns may also interfere with equipment used with livestock (such as
