杜洛克与赣南藏香猪杂交组合性能测定
Performance testing of a hybridized combination between Duroc and Gannan Tibetan pig
摘要
Abstract
[Objective]This study aimed to evaluate growth performance,slaughter characteristics,and meat quality traits in hybrid offspring from Duroc and Gannan Tibetan pig crossbreeding,while analyzing changes in production efficiency.[Method]Three Duroc boars were crossbred with three Gannan Tibetan sows,with their offspring divided into groups for rearing.Upon reaching physical maturity,two pigs from each group were randomly selected and slaughtered to determine the various production parameters.[Result]The results showed that compared with Gannan Tibetan pigs,the body weight of Dugan hybrid offspring was significantly increased(P<0.05),the slaughter rate and lean meat rate were significantly increased(P<0.05).There was no significant change in crude protein content in longissimus dorsi muscle(P>0.05),but the meat color score was significantly reduced(P<0.05),and the muscle fiber diameter was significantly thicker(P<0.05).The muscle fiber density decreased significantly(P<0.05),but the flavor amino acid content decreased significantly(P<0.05).[Conclusion]The findings indicate that using Duroc as the sire effectively enhances growth performance in hybrids,yet leads to a noticeable decline in pork quality.关键词
