日粮添加琥珀酸对清远麻鸡屠宰性能和肉品质的影响
Effects of dietary succinic acid on carcass performance and meat quality of Qingyuan partridge chicken
摘要
Abstract
In this study,we investigated the effects of dietary succinic acid on the carcass traits and meat quality of Qingyuan partridge chickens.A total of 210 75-day-old female Qingyuan partridge chickens were selected and randomly divided into 3 groups,with 5 replicates in each group and 14 chickens per replicate.The control group was fed with basal diet,while the other two groups were fed with diets contai-ning 0.1％and 0.2％succinic acid,respectively,for 40 days after 3 days' pre-feeding.At the end of the experiment,two chickens were eu-thanized from each replicate and tissue samples for carcass performance determination were collected according to agricultural industry stand-ards.Then,serum samples were collected for determination of serum biochemical indexes.Next,thigh and breast muscle samples were col-lected for determination of meat quality and nutritional component by reagent kits and related instruments.Finally,the expression of genes re-lated to protein metabolism and lipid metabolism in the thigh muscle,breast muscle,abdominal fat,and liver were tested by real-time fluo-rescence quantitative PCR.The results showed that the chickens fed with 0.2％succinic acid improved their breast muscle yield(P＜0.05)and crude fat(P＜0.05),compared with the control group.The chickens fed with 0.1％succinic acid had reduced the shear force in them(P＜0.05),compared with the control group,and the tenderness of their breast muscle was increased.The chickens fed with 0.2％succinic acid had reduced the mRNA expression of A-FABP in their abdominal fat(P＜0.05),and the chickens fed with 0.1％succinic acid had re-duced the mRNA expression of SREBP-1c in their liver(P＜0.05),but had no significant effect on their abdominal fat rate.These findings indicated that a diet supplemented with succinic acid could increase their carcass performance and meat quality with no negative effects on their growth performance.关键词
