不同血清对水牛早期胚胎性别比率的影响

Effects of Different Sera on the Water Buffalo Preimplantation Embryo's Sex Ratio

研究了不同血清对水牛早期胚胎性别比率的影响。结果表明,同种血清不同批次对胚胎性别比率没有影响。添加胎牛血清组3个不同发育阶段雄性胚胎比率之间差异显著(P<0.05),随着细胞数目的增加雄性胚胎比率不断增加。添加发情牛血清组3个不同发育阶段雄性胚胎比率之间差异显著(P<0.05),但不同于胎牛血清组,未出现随着细胞数目的增加而雄性比率不断增加的现象。无血清组两个细胞期雄性胚胎比率之间差异不显著(P>0.05)。

The experiment was carried out to study the effects of different sera on the water buffalo preimplantation embryo＇ s sex ratio. The results indicated that differernt batches of the same surem had no influence on the embryo＇s sex ratio, the sex ratio of male embryos within fetal bovine serum （FBS） were significant different in there differernt cell stage （P〈0.05）. Along with the increase of the number of blastomeres, the sex ratio of male embryos was higher. The sex ratio of male embryos within oestrus cow serum （OCS） were significant different in there differernt cell stage （P〈0.05）, but it is different from the former, the sex ratio of male embryos was not higher along with the increase of the number of blastomeres. The sex ratio of male embryos without serum was not significant different in two differernt cell stage （P〉0.05）.
