摘要
在相同环境条件下,对东北野猪与PIC猪杂交子一代和PIC猪在繁育性能、生长性能和产出效益进行比较分析。结果表明,杂交子一代产仔数低于PIC猪,差异显著(P<0.01),弱仔率上差异不显著(P>0.05);在育成率上两者相近,差异不显著(P>0.05);出生窝重、断奶窝重及平均日增重方面低于PIC猪,且差异显著(P<0.01);胴体重差异不显著(P>0.05),杂交猪的瘦肉率高于PIC猪,差异显著(P<0.01),防疫成本和饲喂成本低于PIC猪,差异显著(P<0.01)。
Performances of reproduction and growth and output benefit of F1 hybrid ( Northeast wild boar x PIC pig) and PIC pig bred in same conditions were compared.Results showed that differences in litter size were signitlcanly ( P 〈0.01 ) lower in hybrid F1 and differences of percentage of weak piglets not significant ( P 〉 0.05) ; in litter size at weaning, difference was not significant ( P 〉 0.05) ; the birth weight and weaning weight of liners and average daily gains were lower in F1 hybrid than in PIC pigs, differences were significant ( P 〈 0. 01 ), differences in body weight were not significant ( P 〉 0. 05), lean meat percentages were higher in FI hybrid than in PIC pigs, differences were significant ( P 〈 0.01 ), epidemic prevention costs and feed costs were lower in F1 hybrid than in PIC pigs difference were significant (P 〈 0.01) .
