Superovulation was induced in 129 lactating donor cows for embryo transfer under field conditions. Twenty-nine animals (22.5 per cent) responded with fewer than three corpora lutea. The number of animals flushed was ninety-nine, averaging 8.2 corpora lutea per donor cow. The average proportion of recoveries was 56.4 per cent. The quality of the embryos was satisfactory in 64 per cent of the cases. The average number of embryos and egg cells per donor was 4.6, which resulted in 2.9 good quality embryos per donor. The percentage of pregnant recipients was 56 in good quality embryos and 9 for fair quality embryos.
在田间条件下，对129头泌乳供体奶牛进行超数排卵以进行胚胎移植。29头动物（22.5%）的黄体数少于3个。冲胚的动物有99头，每头供体奶牛平均有8.2个黄体。平均回收率为56.4%。64%的情况下胚胎质量令人满意。每个供体的胚胎和卵细胞平均数量为4.6个，即每个供体有2.9个优质胚胎。优质胚胎的受体妊娠率为56%，中等质量胚胎的妊娠率为9%。
