不同杂交组合对哈萨克羊后代屠宰性能影响的研究
Study on the Effect of Different Crossbreeding Combinations on Slaughter Performance of Kazakh Sheep Progeny
摘要
Abstract
To investigate the differences in slaughter performance among different crossbred progenies of Kazakh sheep and Texel sheep,this study selected Kazakh sheep from the Zhaosu Horse Farm in Xinjiang,including Texel×Kazakh F1,Texel× Kazakh progressive backcross F2,and Texel× Kazakh backcross F2,with 10 males and 10 females in each group.After slaugh-ter,their slaughter performance was measured.The results showed that in terms of pre-slaughter live weight,Texel × Kazakh F1>Texel × Kazakh progressive backcross F2>Texel× Kazakh backcross F2>Kazakh sheep,with both male and female Texel × Kazakh F1 being significantly higher than Kazakh sheep.The loin eye area of Texel× Kazakh F1 rams was higher by 47.56%and 17.19%compared to Texel× Kazakh progressive backcross F2 and Kazakh sheep,respectively.Significant differences were observed in tail fat weight among all crossbreeding combina-tions,with both male and female Texel× Kazakh progressive backcross F2 having zero tail fat weight.There were signifi-cant differences among different crossbred Kazakh sheep combinations in terms of ewe loin eye width,backfat thick-ness,tail fat weight,and loin eye area.The loin eye area of Texel × Kazakh progressive backcross F2 ewes was signifi-cantly larger than that of Kazakh sheep,exceeding the latter by 22.98%,while the backfat thickness of Texel × Kazakh backcross F2 was 71.61%higher than that of Texel × Ka-zakh progressive backcross F2.In summary,crossbreeding Texel sheep with Kazakh sheep can significantly improve muscle development and reduce fat deposition in the proge-ny.However,due to the weakening of traits such as muscle development and fat deposition during backcrossing,it is rec-ommended to appropriately increase the proportion of Texel bloodline in the breeding process to achieve better improve-ment results.关键词
