摘　　要：为了筛选与崇明白山羊杂交的优势组合,选用波尔山羊♂、萨能山羊♂、崇明白山羊♂各两头分别与20头崇明白山羊♀进行交配,研究不同组合对繁殖性能和血清乳酸脱氢酶(LDH)活性的影响。试验结果表明:①就繁殖性能而言,波尔山羊、萨能山羊与崇明白山羊杂交后,体现出一定的杂交优势。其中,波尔山羊的杂交效果比萨能山羊的杂交效果明显,每头母羊胎产羔2头,活羔1.71头,产羔率为200%,羔羊的断奶成活率平均为100%,产活羔数、产羔率、羔羊成活率、断奶活羔数均为三组中最高,是生产中较为理想的杂交父本。②三种成年公羊血清LDH活性由小到大的顺序是波尔、萨能、崇明,以崇明白山羊的活力为最高;在后代羔羊中,波尔与崇明杂交一代公羊的LDH活性高于萨能杂交一代公羊,也高于崇明羊自交后代,可辅助判断出波尔与崇明羊的杂交优势高于萨能羊,可能是较优杂交组合。The objective of this study was to select dominant combination.Two male Boer goats,Saanen goats and Chongming white goats were used respectively to mate with 20 female Chongming white goats to study effects of different combination on reproductive performance and the activity of LDH.Experimental period started from pregnant to 60 day old for 7 months.Regular breeding and caring methods were adopted during trail period.The results showed that 1）so far as reproductive performance was concerned,heterosis was showed when Boer goats and Saanen goats crossbred with Chongming white goats,hybrid effect of Boer goats was better than Saanen milk goats,goats had 2 young at a birth,survival lamb was 1.71,the rate of lambing was 200%,average ratio of survived lambs was 100%,1.71 weaning lamb was reproduced by per labor goat.Number of lambs born alive,lambing rate,survival rate of lamb,weaning lamb were the highest among three groups,was an ideal male parent for application.2） The activity of serum LDH of three type adult male goats was ordered by Boer,Saanen,Chongming goats in turn,the activity of serum LDH of Chongming was the highest among three varieties;in offspring of lambs,activity of serum LDH of Chongming goats was higher than Saanen hybrid male goats and Chongming self fertile,which can be judged as assistance that hybrid heterosis between Boer and Chongming was higher than F1 mail goats,and it should be the better cross combination.
