摘要
不同品种杂交配套是地方猪资源开发的重要途径。为获得兼顾生产性能和风味品质的商品代,我国围绕地方猪品种开展不同组合杂交研究。目前杂交组合众多,且尚无针对地方猪杂交利用性能数据统计的报道。本文统计研究较多的18个地方猪及培育品种共119种杂交组合,分析对比后代屠宰率、瘦肉率、眼肌面积、背膘厚、肌内脂肪含量等屠宰性能。结果发现,二元杂交中,各杂交系的屠宰率差异不显著,但其他屠宰性能存在差异(P<0.05);三元杂交中,两广小花猪杂交系的屠宰性能与其他杂交系存在显著差异(P<0.05)本文对高品质猪肉生产、地方猪品种选择和杂交方式组合具有重要参考意义。
The utilization of different breeds is an important way to develop local pig resources.In order to obtain a commercial generation with both production performance and flavor quality,different hybrid studies were carried out around local pig breeds in China.At present,there are many hybrid combinations,and there is no statistical report on the utilization performance of local pig hybridization.In this paper,a total of 119 hybrid combinations of 18 local pigs and bred breeds were statistically studied,and the slaughter performance of offspring was analyzed and compared,such as slaughter rate,lean meat rate,eye muscle area,back fat thickness and intramuscular fat content.The results showed that there was no significant difference in slaughtering rate among the hybrid lines,but there were differences with other slaughtering performance(P<0.05).In threeway hybridization,the slaughter performance of Liangguang Xiaohua pig hybrid line was significantly different from other hybridization lines(P<0.05).This paper has important reference significance for high quality pork production,selection of local pig breeds and combination of hybridization methods.
