野公猪与鄂西黑母猪杂交一代猪与2种家猪生长性能比较

Study on the Growth Performance among the Crossed Wild Swine(Wild Swine(♂) × E-xi Dark Swine(♀))and Two Domestic Swines

对相同饲养管理条件下的17头杂交野猪(野公猪×鄂西黑母猪)、21头长白猪和22头大约克猪的初生重、30日龄重及平均日增重以及杂交野猪从出生到6月龄各阶段的体重及平均日增重进行了测定。结果表明:杂交野猪的公猪和母猪的初生重、30日龄重及平均日增重均分别低于长白猪的公猪和母猪,也低于大约克猪的公猪和母猪,且差异极显著(P<0.01);杂交野公猪的初生重、30日龄重和60日龄重均与杂交野母猪差异不显著(P>0.05),但6月龄重低于杂交野母猪,且差异极显著(P<0.01)。

The birth weight,the weight at 30 days and average daily gain of 17 crossed wild swines(wild swine(♂)× E-xi dark swine(♀)),21 Landrance and 22 Yorkshine in the same management condition,and the weight,average daily gain of the crossed wild swine from born to 6 months were measured.The results showed : the birth weight,the weight at 30 days and average daily gain of the male swine and the female swine of the crossed wild swine was lower than those of the male swine and the female swine of Landrance and the male swine and the female swine of Yorkshine.The difference was very significant(P<0.01);the difference of the birth weight,the weight at 30 days,the weight at 60 days between the crossed wild male swine and the crossed wild male swine was not significant(P>0.05),but the weight at 6 months of the crossed wild male swine was lower than that of the crossed wild female swine,the difference was very significant(P<0.01).
