研究应用性控精液对超排育成牛和成母牛输精,生产性控胚胎.结果表明:非性控精液组受精卵数同性控精液组相比差异不显著(P＞0.05),但可用胚胎比例高于性控精液组(90.17%对89.73%,66.03%对63.57%).育成牛群组受精卵比例高于成母牛群组(92.74%对84.93%)差异不显著(P＞0.05);但可用胚胎比例显著高于成母牛群组(68.77%对55.28%)(P＜0.05).1次输2支性控精液组中,育成牛群组受精卵数、可用胚胎比例都显著高于成母牛群组(90.83%对79.69%,67.89%对53.13%)(P＜0.05).2次人工授精,每次输1支性控精液组中,育成牛群组受精卵及可用胚胎比例都显著高于成母牛群组(93.75%对87.41%,69.23%对56.30%)(P＜0.05).
