Abstract:

In order to determine the slaughter performance,physicochemical indicators of meat product and processing characteristics in donkey of different breeds,we selected Guanzhong donkey,Dezhou donkey,Guangling donkey,Qingyang donkey,Biyang donkey,Jiangyue donkey,Yunnan donkey on 7-month-old and tested their slaughter performance,moisture content,protein content,intermuscular fat content,shear force,rate of cooked meat of longissimus and rump.The results showed that Dezhou donkey on 7-month-old in live weight,carcass weight and net meat weight were significantly higher than other breeds(P<0.05),as well as higher net meat percentage than Guanzhong donkey,Qingyang donkey and Yunnan donkey(P<0.05).Jiangyue donkey had higher slaughter rate than Guanzhong donkey,Qingyang donkey,Biyang donkey and Yunnan donkey(P<0.05).Guangling donkey and Guanzhong donkey had more than 2% intermuscular fat content,intermuscular fat content of longissimus were higher than Biyang donkey and Yunnan donkey(P<0.05),while intermuscular fat contents of rump were higher than other breeds(P<0.05).The shear force of longissimus of Guangling donkey,Guanzhong donkey and Dezhou donkey were lower than Biyang donkey and Yunnan donkey(P<0.05).Dezhou donkey was significantly different(P<0.05) from Guangling donkey,Guanzhong donkey and Qingyang donkey,showing a higher rate of cooked meat of longissimus,and was significantly different(P<0.05) from Guangling donkey,Guanzhong donkey,Biyang donkey,Qingyang donkey and Jiangyue donkey,showing a higher rate of cooked meat of rump.Thus,Dezhou donkey have the excellent potential of meat production.Jiangyue donkey,Guangling donkey and Guanzhong donkey also have potential for meat development.Guangling donkey and Guanzhong donkey have good ability to store fat,which have the potential to become high-grade raw meat.
