Effects of back fat, growth rate, and age at first mating on Yorkshire and Landrace sow longevity in China
In the present study, genetic parameters for longevity and genetic correlations with back fat (BF), average daily gain (ADG), and first mating age (FMA) were estimated from 19 300 Yorkshire and 18 378 Landrace sows from 12 farms derived from one breeding system. General linear models (GLM) were empl...
