Typically, a sow gives birth to between 9 and 12 piglets, but the range can be from 6 to 24.

Sows have a 21-day estrus cycle, giving birth after a 114-115 day gestation period, followed by 17-28 days of lactation. They can have appx. 2.3 litters per year.

Teaser boars help detect estrus in sows and stimulate ovulation, thus increasing reproductive performance.

Sows are typically ready for breeding at around 150 kg body weight.

Primary goals in pig breeding include maximizing the number of piglets born alive, minimizing pre-weaning mortality, and improving animal lifespan throughout their productive lives.

Canada exports about two-thirds of its pork production, worth approximately $4.82 billion annually.

Pigs typically reach market age in 5-6 months.

A pig breed known for erect ears.

A pig breed characterized by floppy ears.

Specialized companies maximize genetic progress in pigs using advanced technology and breeding programs.

Sow productivity is a low-heritability trait in pig breeding.

Carcass merit is a medium to high heritability trait in pig breeding.

Crossbreeding in pigs involves combining different pig breeds, like the Yorkshire, Hampshire, and Duroc, for desired traits.

A young female pig that has not yet given birth or been slaughtered.

A mature female pig that has given birth.

A mature male pig that is used for breeding.

A castrated male pig.

A pig that has just been weaned from its mother.

A pig that is being raised to be slaughtered for meat.

The Canadian pork industry is a free market, meaning prices are determined by supply and demand. It is heavily reliant on exports and has no supply management system.

Vertical integration occurs when one company controls multiple steps in the pork production process, from breeding to processing and distribution.
