摘要 本试验分别在新疆和河北2个不同牛场进行了饲草料质量对受体牛胚胎移植妊娠率影响的研究。阿克苏牛场饲喂正常饲草组,受体母牛胚胎移植的妊娠率为54.31%(63/116);饲喂发霉变质饲草组,受体母牛妊娠率为26.75%(88/329)。河北牛场未饲喂棉籽壳组,妊娠率为51.79%(29/56),饲喂未经脱毒处理或脱毒不完全的棉籽饼/壳组,妊娠率只有6%(3/50)。结果表明,饲喂霉变饲草、未经脱毒或脱毒不完全的棉籽饼/壳,可严重降低受体母牛胚胎移植后的妊娠率。 Frozen embryos were transferred on two different cattle farms to study the effect of the forage quality on pregnancy rate of recipient heifers. On one farm the pregnancy rates of recipients in normal feeding and mold forage groups were 54.31%(63/116) and 26.75%(88/329), and on another farm were 51.79%(29/56) and 6%(3/50) in normal and cottonseed/shell feeding groups, respectively. The pregnancy rate of recipients was reduced severely after embryo transplantation if animals were fed to mold forage or cottonseed/shell with gossypol.
