Average Birth Weight and Uterine Capacity

The basis for balanced breeding is in the farrowing house. Average birth weight is often cited as a very important trait for future success. That appears to be true, but also contradicts with the number of total born piglets. Weight uniformity is a better predictor of success in the life of the pig. The maximum capacity to produce uniform, heavy and good quantity pigs in one litter depends upon the uterine capacity of the sow.
