绿嘉黑猪的不同杂交组合生长性能、胴体品质、产肉性能和收益比较研究
Comparative study on growth performance,carcass quality,meat performance and profit-ability of different crossbreed combinations of Lvjiahei pigs
摘要
Abstract
To investigate the crossbreeding utilization pattern of Lvjiahei pig as the maternal parent,this experiment was carried out to produce crossbreed combinations of Landrace pig ♂ × Lvjiahei ♀(LL),Yorkshire pig ♂ × Lvjia-hei ♀(YL)and Duroc pig ♂ × LvJiaHei ♀(DL).The growth performance of the offspring from the three cross-breed combinations at 180 days of age was measured,and the carcass quality,meat production performance and prof-itability of the Duroc × Landrace × Yorkshire(DLY)and the three crossbreed combinations were compared.The re-sults showed that in the aspect of growth performance;the body length of LL and YL was significantly higher than that of DL(P<0.05);the body height of DL was significantly higher than that of YL and LL(P<0.05);the live backfat thickness of LL and YL was significantly lower than that of DL(P<0.05).In the aspect of carcass quality,the carcass length of LL and YL were significantly higher than that of DL(P<0.05);35.71%of the DL's carcass weight was graded as Class Ⅱ and 64.29%was graded as Class Ⅲ,showed the best performance.In the aspect of meat production performance and profitability,DLY had a significant higher proportion of loin in the carcass com-pared than that of LL(P<0.05);DL had a significant higher proportion of loin,belly fat and pork shank in the car-cass compared with that of YL and LL(P<0.05).The sales revenue from the half carcasses of DL,YL,LL and DLY were 1 402.83,1 385.21,1 309.05 and 1 108.65 yuan,respectively.The refined segmentation sales revenue of DL was the highest.Crossbreeding Lvjiahei with Landrace,Yorkshire and Duroc pigs,the offspring of the cross-breed combinations showed that LL had the fastest growth rate,and DL had good carcass quality and high profitability in fine segmentation.关键词
