摘要
目的:为了探讨不同配种方法对努比亚山羊情期受胎率、年均产羔数和后代羊生长性能的影响。方法:选择产龄和体重相近的努比亚母羊120只,随机分为6组,每组20只,分别以情期本交配种1次和2次;山羊人工授精配种1次,输精量0.6 mL/次;人工授精配种1次,输精量0.8 mL/次;人工授精配种2次,输精量为0.6 mL/次;人工授精配种2次,输精量为0.8 mL/次进行试验。结果:不同的配种方法对努比亚母羊情期受胎率和年均产羔数有一定影响,各组间相比较差异不显著(P>0.05);山羊人工授精能提高后代羊的生长性能,但效果不显著(P>0.05)。结论:采用山羊人工授精早、晚各配种1次,每次输精量0.8 mL效果最佳。
Objective: to study the effects of different mating methods on the period of conception rates, lambing numbers and growth performance of offspring in Nubian goats, 120 Nubian goats were selected. Method: the Nubian goats with similar production age and body weight were divided into 6 groups randomly of 20 goats each, The mating methods as followed : ( 1 ) mating one, (2) mating 2 times, ( 3 ) artifical insemination once with 0.6 mL of semen, (4) artifical insemination once with 0.8 mL of semen, ( 5 ) artifical insemination 2 times with 0.6 mL of semen pertime, ( 6 ) artifical insemination 2 times with 0.8 mL of semen pertime.Resuk: the results indicated that there was no significant difference in the period of conception rates (P〉0.05) , lambing numbers ( P〉0.05 ), and growth performance of offspring ( P〉0.05 ).Conclusion : the mating method of artifical insemination 2 times with 0.8 mL of semen oertime was the best metod.
