Fun Facts Most of Alberta’s sheep farms have crossbred ewes. Crossbreeding combines the traits of two or three different breeds. Crossbreeding also adds what is called hybrid vigour, which helps improve productivity. The main source of income from sheep in Canada is from producing lambs for meat. Wool is a secondary product in most flocks. Sheep dairy is a very small industry in Canada. Lambskin is a by-product of meat processing, and is used in high quality leather goods. Sheep are ruminants that graze and browse. They are able to eat woody plants, weeds, grasses, and grains that humans can’t. They efficiently convert those plant materials into high quality meat, wool, milk, and leather. Flocks of sheep can be used to control vegetation on farms, in cattle grazing areas, and in reforested areas. 1 4-H Sheep Project Guide Level 2 Canadian wool sheep must be shorn once a year. Wool grows continually providing sheep with protection against Canada’s climate. Wool is a valuable fiber that is used for fabrics, clothing, felt, and even insulation. It is a renewable resource. Wool has even been used to clean up oil spills; it can be squeezed out and reused up to eight times. Coyotes are the most common predator of sheep in Alberta. Other predators include foxes, wolves, cougars, bears, and ravens.

Purebred sheep carry Sheep the genetics of one breed, can have registration papers that guarantee the parentage of the animals, and must follow the guidelines of Canada’s Animal Pedigree Act. Random DNA sampling of sheep being registered helps assure pure genetics. Pure breeding sheep means to select and reproduce genetically similar animals. The benefit of having purebred sheep is for more genetic predictability. Selection is based on improving breed quality and economically important traits (growth rate, fertility, mothering ability, feed efficiency, and carcass quality). Purebred sheep, in particular terminal sire rams, are commonly used in commercial
