Effect of selection for maternal and direct genetic effects on genetic improvement of litter size in swine.

Journal of animal science - 1 Nov 1993

Roehe R, Kennedy B W

Abstract excerpt

Optimum weighting ratios of maternal:direct EBV for litter size using an animal model were examined to achieve maximum genetic improvement (direct plus maternal response). Stochastic simulation of a 120-sow herd over a 10-yr period of selection was used (20 replicates). Directional selection was based on a merit function of maternal and direct EBV for first-parity litter size. Optimum weighting ratios for...
