摘　　要：本文以CRP配套系母猪系猪为材料,研究其排卵与胚胎活力。结果表明:母系猪排卵数24.14个,比我国地方猪种平均排卵数21.58多2.56个;28～30d胚胎成活率80.35%,大于大约克的69.55%,小于二花脸猪的85.96%。母系猪的高排卵特性和较高胚胎存活率,为品系14.74头的高产仔数提供了生理前提。The paper studied the ovulation rate and embryonic vitality of dam line pigs of CRP multiple cross systems.The results showed that ovulation rate of the dam line pigs was24.14,was2.56more than average ovulation rate of Chinese local pig breeds,the embryonic survival rate for28～30d.was80.35%,bigger than69.55%of Large White Pig,less than85.96%of Erhualian pigs.Hige ovulation rate and higer embryonic survival rate of the dam line bigs offered physiological prerequisite for the high litter size(14)of the dam line pigs.
