Background technique [0002] With the improvement of people's living standards, the demand for livestock products continues to increase, and the breeding industry is developing in the direction of scale and standardization. In the pig industry, sow productivity is critical. However, at present, due to the limitation of feeding technology, the production capacity of sows is generally low. During pregnancy, the number of piglets born alive is low, and the birth weight of piglets is low, resulting in a small number of pigs in stock and slow production speed, which seriously limits the production capacity of sows. The development of the pig industry. Proper feeding and scientific management of pregnant sows are the basis for ensuring the normal development of fetuses in sows, preventing miscarriages and stillbirths, having a large number of litters, and producing healthy, well-p...
