品种和营养水平对猪生长性能、胴体性状和肉质的影响
Effects of Breed and Nutrient Level on Growth Performance, Carcass Traits and Meat Quality of Pigs
摘要
Abstract
The experiment was conducted to investigate the effects of breed and nutrient level on growth per-formance, carcass traits and meat quality of pigs.Twelve pairs of Gaopo pigs and “Duroc ×Landrace ×Taihu”crossbred pigs (DLT) with an initial body weight of (61.16±4.13) kg were randomly assigned to receive Na-tional Research Council ( 2012) diet or Chinese Feeding Standard of Swine ( 2004) diet and slaughtered at an average weight of 90 kg.The results showed as follows:the loin-eye area of DLT was significantly higher than that of Gaopo pigs ( P<0.05) , while the intramuscular fat content, average back fat thickness and meat color L*24 h and b*24 h of DLT were significantly lower than that of Gaopo pigs ( P<0.05) .The feed to gain of pigs was significantly decreased when fed with high nutrient level diet ( P<0.05) .Intake of high nutrient level diet not only increased average daily gain, average daily feed intake, carcass length and meat color a*24 h( P<0.05) , but also decreased meat color L*24 h , drip loss and the relative mRNA expression of sterol-regulatory element binding protein-1c and hormone-sensitive triglayceride lipase of Gaopo pigs ( P<0.05) .Intake of high nutrient level di-et significantly decreased meat color a*45 min and a*24 h of DLT ( P<0.05) .The results indicate that growth per-formance, carcass traits and meat quality of pigs are influenced by breed and nutrient level; carcass traits of DLT is better than Gaopo pigs, while meat quality of DLT is poorer than Gaopo pigs.Intake of high nutrient level diet can improve carcass traits of DLT, meat quality of Gaopo pigs and the growth performances of pigs.关键词
