Study and Analysis on Slaughter Performance of Queshan Black Pig and its Hybrid
摘要
Abstract
To improve the slaughter performance of Queshan Black pig,Queshan Black pig was taken as the female parent,Duroc,Landrace,Yorkshire and Hampshire as the male parent to conduct binary hybrid experiment;Landrace× Queshan was taken as the female parent,Duroc and Yorkshire as male parent to conduct three-way cross experiment.The data were collected to analyze the slaughter performance and carcass traits of offspring of different hybrid combination.Results show the offspring of Landrace× Queshan binary hybrid has higher daily weight gain,dressing percentage,lean meat rate and loin eye area,namely,440.53 g/d,75.05 ％,53.19 ％,and 34.51m2,than Que× Que and other hybrid combination (P＜0.05);the offspring of Yorkshire× Landrace× Que has a significantly higher daily weight gain of 663.76g/d than Duroc× Landrace× Que(P＜0.05),other indices are insignificantly different (P＞0.05);the threeway hybrid combination has significantly higher daily weight gain (629.60 g/d),lean meat rate (57.46％),loin eye area (33.89 m2) than binary hybrid combination(P＜0.05).The experiment reveals Landrace × Que binary hybrid and Yorkshire× Landrace× Que three-way cross combination are superior to other hybrid combinations to some extent,which are better hybrid methods for Queshan Black pig.关键词
