Breastfeeding period: refers to the period from birth to weaning of piglets, which is usually 3 to 5 weeks. Lactating piglets are in the early stages of life, and are susceptible to ill effects due to the external environment. Poor management can also lead to the death of piglets. Therefore, strengthening feeding and management of suckling piglets is the key to improving the survival rate of piglets and the efficiency of raising pigs.

Therefore, it is critical to improve the feeding and management of piglets before and after weaning.

This phase is the fastest growing period for pigs, and it is also an important period for pig farmers to obtain economic benefits. In feeding and management, we must strengthen nutrition supply, provide adequate and clean drinking water, and do a good job of environmental sanitation and epidemic prevention within and outside homes in order to ensure adequate pig growth and development.
