摘要
为探索安格斯牛与不同肉牛品种的杂交效果,以引进澳大利亚黑安格斯母牛为基础,开展安格斯牛、云岭牛、和牛、短角牛、独龙牛和文山牛6个品种公牛进行杂交组合试验,配种比例1:30(公母比例为1:30)。结果表明,安格斯牛群繁殖力高,参配母牛337头,产犊牛314头,产犊率为93.17%,牛群犊牛成活率为99.91%,繁殖成活率为97.64%。其中安格斯牛初生重平均34.16±4.01 kg、短安杂F134.61±5.87 kg、云安杂F133.57±5.80 kg和安杂F132.48±4.06 kg、文安杂F128.10±1.79 kg和独安杂F124.71±6.24 kg。黑安格斯与外来品种间的杂交效果很好,但初生重差异不显著(P>0.05);而文安杂F1初生重明显低于引进肉牛品种的杂交后代(P<0.05),独安杂F1初生重极显著低于引进品种的杂交后代(P<0.01),显著低于文安杂F1(P<0.05)。本研究中初步揭示了安格斯牛不同杂交组合的效果,为将来育种提供了积极的科学参考。
In order to explore the crossbreeding combination of beef cattle breeds in the hot areas,Six bull combinations of Angus,Wagyu cattle,Short-horn cattle,Yunling cattle,Wenshan cattle and Dulong cattle were crossbred with the Black Angus cows introduced from Australia,of which the mating ratio was 1:30(1 male:30 female).The results showed that Angus cattle had high reproductive performance,and 314 calves yielded mating with 337 cows,with a calving rate of 93.17%.The survival rate of calves in the herd was 99.91%,and the reproductive survival rate was 97.64%.Among them,the average birth weight of Angus cattle was 34.16±4.01 kg,while the birth weights of F1 hybrids of Short-horn×Angus,Yunling×Angus,Wagyu cattle×Angus,Wenshan cattle×Angus,Dulong cattle×Angus were 34.61±5.87 kg,33.57±5.80 kg,32.48±4.06 kg,28.10±1.79 kg,and 24.71±6.24 kg,respectively.The hybridization effect of Black Angus crossbreed introduced breeds represented better,of which the birth weights among the crossbreeding combinations was not significant(P>0.05).But the F1 birth weight of Wenshan cattle×Angus was significantly lower than those of the introduced hy-brids(P<0.05),and the F1 birth weight of Dulong cattle×Angus was extremely significantly lower than those of the introduced breed(P<0.01),and significantly lower than that of Wenshan cattle×Angus F1(P<0.05).This study preliminarily revealed the crossbreeding effects of different combinations for Angus cattle,providing positive scientific references for future breeding.
