Brief introduction to the statement of work:
In pigs, females who have given birth at any age are called sows. There are many kinds of sows, divided by color, including black sows, white sows and spotted sows. Their living habits are also somewhat different. Geographically, some sows mainly eat half-cooked, some eat cooked food and some eat raw materials. There are many kinds of sows in China, including Taihu pig, Landrace pig, Large White pig, Erhualian pig, Jinhua pig, Duroc pig, Pitland pig and Rongchang pig.
Breeding time:
Breeding is the process of combining into fertilized eggs and implanting them into the uterus. Therefore, breeding must combine sperm and eggs at the best time to achieve the best pregnancy effect. In pig production, breeders must master the characteristics of each pig and breed oestrus sows in time. In fact, sperm are usually activated 25-30 hours after mating. The more accurate mating time is that ovulation is the best time for sperm to just reach the fallopian tube after mating.
