摘要
来自3个羊场的60只波尔山羊被随机分成输卵管采卵组和子宫角采卵组。结果表明:用输卵管采卵法采集的30只羊的总采卵数、总有效卵数和平均有效卵数分别为583、484和17.9枚,子宫角法采集的30只羊的相应卵子数为505、461和16.5枚。前者明显高于后者,但后者却较前者多产羔34只(252比218),其差异极显著(P<0.01)。
adult female Boer goats from 3 farms were randomly divided into two groups. The total ovulation, available ovulation and average ovulation collected from oviduct are 583, 484 and 17.9 (group A), all of them are more than that from uterine horn (group B). But in group B, 34 more kids were produced. There was a significant difference in reproduction rate between two groups (P<0.01).
