How to improve the reproductive efficiency of sows and thus increase the litter size has become a topic of general concern to farmers. How to do it in the daily feeding management process?

1. Strive to increase the annual litter size of sows. For example, comprehensive measures should be taken to improve the conception rate and delivery rate of pregnant sows, early weaning technology should be implemented to shorten the lactation period of piglets as much as possible, and piglets should be bred in time after weaning. We should work hard towards the goal of five nests in two years.

2. Do everything possible to increase the number of live piglets per litter. For example, strengthening the feeding management of sows to make follicles develop normally, timely mating, paying attention to semen quality, repeated mating, improving the feeding environment of sows, strictly controlling feed quality, and vaccinating to prevent infectious diseases that can cause reproductive disorders of sows.

3. Improve the survival rate of suckling piglets. Do a good job in sow midwifery, keep piglets warm, eat colostrum early, improve dietary supplements, supplement iron, selenium and other preparations, and inject vaccines to reduce the occurrence of infectious diseases such as diarrhea.
