Evaluation of Hybrid Combination Effect between Different Breeds of Meat Sheep and Local Han Hybrid Sheep
摘要
Abstract
In order to explore the evaluation of the hybrid combination effect of different breeds of meat sheep and Jinta local Han hybrid sheep.In this experiment,excellent meat sheep breeds,White Dorper sheep,Australian White,White Suffolk sheep,East Frisson and small tail cold sheep were selected as sires,and Jinta local Han hybrid sheep were selected as dams to conduct hybrid experimental research,and the reproductive performance,hybrid advantages and F1 generation production performance of different hybrid combinations were observed and determined.The results showed that in terms of breeding performance,the av-erage lambing rate of small-tailed cold sheep×local Han hybrid sheep was the highest at 207.69%,followed by White Dorper sheep×local Han hybrid sheep(173.33%),and the average lambing rate of Australian White×local Han hybrid sheep was the lowest at 157.14%.Except for the small-tailed cold sheep×local Han hybrid sheep group,the survival rate of lambs in the oth-er hybrid combinations is above 90%.In terms of hybrid advantage,the weight,body height and body length of different combi-nations at birth,3 months and 6 months of age showed obvious hybrid advantage,especially with weight,among which the 3-month-old weight hybrid advantage rate of White Dorper sheep×local Han hybrid sheep reached 14.66%,and the 6-month-old weight hybrid advantage rate reached 12.70%.In terms of growth performance,the average daily gain of the hybrid group imported from abroad was significantly higher than that of the small tail Han sheep hybrid group(P<0.05).It can be seen that introducing different breeds of meat sheep and Jinta local earth-cold sheep for hybridization can improve the reproduc-tive and growth performance of meat sheep,and the F1 gen-eration has obvious hybrid advantages.关键词
