Fertilization rate in sheep unilaterally inseminated with frozen semen 收藏

绵羊单侧受精冷冻精液的受精率
摘要
In order to evaluate a simple surgical technique for artificial insemination (AI) with frozen semen, 40 adult ewes were synchronised with vaginal sponges impregnated with 60 mg of medroxyprogesterone acetate for 12 d and a single injection of 400 IU PMSG at sponge withdrawal. Semen from fertile rams was pooled and frozen in straws, each containing 3 × 108 spermatozoa. All ewes were inseminated 60 h after PMSG injection. Twenty ewes (group A) were unilaterally inseminated by a small midventral laparotomy and 20 (group B) were cervically inseminated. Fertilization rate was measured by flushing of uteri and oviducts throughout a laparotomy carried out 3–4 d after insemination. The 83.7% fertilization rate in group A was significantly different (P

为了评估用冷冻精液进行人工授精(AI)的简单手术技术,将40只成年母羊与用60mg醋酸甲羟孕酮浸渍12天的阴道海绵同步,并在海绵戒断时单次注射400IU PMSG。将来自肥沃公羊的精液合并并用吸管冷冻,每个吸管含有3×10 8 精子。在PMSG注射后60小时,所有母羊都被授精。 20只母羊(A组)通过小型腹腔切开术单侧受精,20只(B组)进行宫颈受精。通过在授精后3-4天进行的剖腹手术中通过冲洗子宫和输卵管来测量受精率。 A组受精率为83.7%,差异显着(P <0.05)
