Analysis on Fattening Performance and Carcass Traits of Yorkshire, Duroc and Berkshire Pigs
摘要
Abstract
To determine and analyze the fattening and carcass traits of Yorkshire,Duroc and Berkshire pigs that were selected after four generations' breeding,14 healthy Yorkshire,Duroc and Berkshire pigs with body weight of about 30.00kg were chosen and divided into three groups by species.During the test,all of the pigs were fed diet with the same nutritional level (early stage:DE 13.58 MJ/kg,CP16.07%;late stage:DE 13.40 MJ/kg,CP14.66%),and four pigs (two sow and two boars) were selected for slaughter test at the end of the fattening test.The results showed during full test period,the average daily gain of Yorkshire (852.17 g) was significantly higher than that of Berkshire(741.08g)(P<0.05);for feed to gain ratio,Yorkshire was the lowest,being 2.57,Berkshire was the highest,which was 2.98.Lean meat percentage of Berkshire (60.61%) was significantly lower than that of Yorkshire (65.65%)(P<0.05).In conclusion,under the experimental conditions,fattening performance and carcass traits of Yorkshire were the best,Duroc better,Berkshire the worst.关键词
