Genetic Parameters for Feed Efficiency Indicator Traits in a Rotational Crossbreed Sow Population During Lactation Period
ABSTRACT The selection of feed efficient sows effectively converting feed into milk production and body weight gain will contribute to the overall profitability of pig farming systems. Consequently, the aim of the present study was to estimate genetic parameters for feed efficiency indicator traits during the sow lactation period, and to infer respective genetic and phenotypic relationships. Daily feed intake (FI), milk yield (MY), sow weight at farrowing (SWF), litter birth weight (LBW), sow weight at weaning (SWW …
