Abstract
Under the conditions of this study, it was possible to select gilts at weights of about 125 lb. for the largest number of normal embryos at 25 days after breeding, basing selection entirely on feminine characteristics of head and neck. The reproductive advantage gained via such selection apparently results primarily from increased ovulation rates rather than greater embryo survival.This publication has 1 reference indexed in Scilit:
