Canada is one of the world ’ s leading pork producing nations We produce about 30 million pigs each year of which about 23 million stay in the country to be processed

Swine Breeds Major Canadian breeds include the Yorkshire (44%), Landrace (33%), Duroc (14%), Hampshire (7%), the Lacombe and smaller populations of other breeds
Each breed is characterized by its own unique attributes relating to litter size, growth rate, feed conversion, carcass structure and composition.
Characteristic leanness, growth rate, feed conversions Males are virile and aggressive breeders Females are known for their milking ability and the farrowing of large litters of strong, vigourous piglets Used most often in crossbreeding programs for commercial operations Yorkshire
Landrace well muscled white breed noted for its high quality carcass Female, used in purebred and crossbreeding programs, is well known for its excellent mothering ability, temperament, longevity and prolific reproduction. The boars are dependable breeders and have an excellent temperament breed is highly desired for its average daily gain, feed conversion and leanness
Landrace
Duroc Solid red, meat type animal, is noted for its carcass characteristics and feed efficiency Strong feet and legs, large litters, a charactistic retained even when used in a crossbreeding program Commonly used as a terminal sire in crossbreeding programs, as well as the third breed in rotational breeding situations
Duroc
Hampshire well muscled pig provides good carcass muscling and when used in a crossbreeding program black in color with a white belt around the body that includes the shoulder and front legs.
