中文摘要 | 【目的】研究波尔山羊青年母羊体质量与超数排卵反应及回收胚胎数之间的关系。【方法】将12~18月龄的波尔山羊青年母羊57只,按体质量分为26~30,36~40,41~45,>35kg5个组,分析超数排卵处理青年母羊后,不同胚胎回收范围内母羊数量的分布情况及青年母羊不同体质量范围回收胚胎(卵)总数和可用胚胎数,并对青年母羊超数排卵处理后体质量与回收的胚胎(卵)总数及可用胚胎数的关系进行线性回归分析。【结果】(l)青年母羊有52.94%个体的回收胚胎(卵)总数≥16枚,有39.22%个体的可用胚胎数≥16枚。(2)用体质量>36kg青年母羊进行超数排卵,可以得到较多的回收胚胎(卵)总数及可用胚胎数。(3)体质量与回收胚胎(卵)总数之间有较强的相关关系,且相关性达显著水平,并建立了二者之间的回归方程。【结论】波尔山羊青年母羊体质量与超数排卵效果之间有密切的关系,将青年母羊配种前进行良好的饲养,有利于其繁殖潜能的发挥。 |
英文摘要 | 【Objective】The purpose of this paper was to study the relationship between body weight and response to superovulation in young Boer goals. 【Method】In this study, 57 12-18-month-old female Boer goats were divided into five groups according to their weights (26-30, 31- 35, 36-40, 41-45, >45kg). Then the distributions of does goats within the range of different numbers of embryos/ovum were analyzed and the superovulatory effects within different body weights in young Boor does were compared, meanwhile the data of body weights, number of total recovery embryos/ovum and transferable embryos were analyzed by linear regression analysis, 【Result】 The results indicated that: (1) Total embryos/ovum and transferable embryos were more than 16 from 52.91% and 39.22% of young does respectively. (2) The higher number of total embryos/ovum and transferable embryos could be recovered from young does whose body weights were more than 36kg. (3) There was a correlation between body weight and the total numbers of recovery embryo/ovum. The regression equation was established. 【Conclusion】 The body weight of young does is closely related to superovulation. A good feeding before puberty will be beneficial to reproductive potentials. |
