2. Definitions Female after giving birth: Sow Young female: Gilt Having piglets: Farrowing Male: Boar Castrated Male: Barrow Pork: Product made from pig

3. 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

7. Pork producer numbers, like all farm numbers, have continually declined, down by 86% from the highest number of 20,354 pork producers in 1979.

8. Swine Breeds Major Canadian breeds include the Yorkshire (44%), Landrace (33%), Duroc (14%), Hampshire (7%), the Lacombe and smaller populations of other breeds

9. Each breed is characterized by its own unique attributes relating to litter size, growth rate, feed conversion, carcass structure and composition.

10. 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

12. 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

13. Landrace

14. 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

Performance Testing Finished pigs are evaluated using ultrasound measured backfat thickness, live weight, age and average daily gain Info is then related back to boar EPD Sow’s EBV (estimated breeding value) is determined by litter size, the total weaning weight of the litter while taking into account the number weaned Info courtesy of http://www.canswine.ca/

20. Estimated Breeding Value Estimated Progeny Difference Trait is expressed as a + or - compared to the average for the breed EBV vs EPD
