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 three-way 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.
