When do piglets wean?

The suitable weaning time of piglets should be determined according to the specific conditions of each pig farm (household). Previously, general breeding pig farms were weaned at the age of 56-60 days, and commercial pig farms were weaned at the age of 45-50 days. With the development of pig equipment, nutrition and feed science, many qualified pig farms (households) have generally adopted the method of early weaning at the age of 2 1 ~ 28 days, and some weaned at the age of 18 days. Early weaning shortens the lactation period, sows are in good health at weaning, and can be estrus and mated quickly after weaning, which improves the annual production capacity of sows.

Generally speaking, it is best not to wean piglets before 2 1 year, otherwise it will bring many difficulties to the artificial cultivation of piglets and affect the survival rate of piglets. Therefore, the weaning time of piglets in each pig farm (household) should be determined according to its production equipment, feed conditions and management level. Those with good conditions can be advanced appropriately, and those with poor conditions can be postponed appropriately.

When piglets are weaned in batches at the same time, individual extremely thin piglets in each litter can be picked out and gathered together, and weaned sows with good lactation performance can be selected for breastfeeding for one week, which can reduce the death of these piglets after weaning.

The cumulative feed intake of weaned piglets at the age of 4-5 weeks during lactation should be above 600g, and weaned piglets should be healthy and lively, without symptoms such as diarrhea, fever, cough and anemia.
