摘　　要：选择３６头青年母猪进行超数排卵，发现孕酮含量与黄体数（排卵点数）呈显著相关（ｒ＿１＝０．４４４１，ｐ＜０．０１）；但与冲出胚胎数没有相关（ｒ＿２＝０．２２９６，Ｐ＞０．０５）；与２细胞以上胚胎数（不包括２细胞）均表现出强正相关（ｒ＿３＝０．６６９２，Ｐ＜０．０１）。因此，孕酮含量在一定程度上可作为胚胎发育阶段的指标。Thirty six gilts were superovulated, The progesterone content. Progestrerone level significantlycorrelated witb the number of ovulation points(corpus luteum)(r_1=0.4441,P<0.01 );there was not statisticallysignificant correlation between progesterone level and the number of colleeted cmbryos(r_2=0. 2296,P>0.05);progesterone level was strongly correlative.with the number of three to eight-cell cmbryos(r_3 = 0.6692,P<0.01).So,the progesterone content could be,to a greater or lesser exten, consideted a parameter of embryoniestage.
