[目的]选用320只1日龄AA肉公鸡,研究谷胺酰胺和天冬胺酰胺对肉鸡部分脂肪性状、血脂指标及相关生脂基因mRNA表达水平的影响,研究2种氨基酸对肉鸡脂代谢的影响机制.[方法]采用双因子完全随机设计,将试验鸡按体重随机分为4个处理组,分别在玉米-豆粕型基础饲粮中添加1%的谷氨酰胺和天冬胺酰胺,试验期为42 d.屠宰后测腹脂率,游标卡尺测皮下脂肪和肌间脂肪厚度,比色法测定血清甘油三酯(TG)、胆固醇(TC)、高密度脂蛋白固醇(HDL-C),RT-PCR技术检测肝脏、腹脂组织中乙酰辅酶A羧化酶(ACC)、脂肪酸合成酶(FAS)、肉毒碱棕榈酰基转移酶Ⅰ(CPT-1).脂蛋白酯酶(LPL)、肉毒碱棕榈酰基转移酶α(PPAR α)mRNA水平的...

[ Objective ] An experiment was conducted using a total of 320 one day old AA male broiler chickens to investigate the effect of dietary supplemented with glutamine and aspartic on fatty traits, blood fat levels, adipogenesis genes mRNA level in liver and coelo-grease and the possible mechanism of their function to lipid metabolism of broiler. [Method] The broilers were randomly tested by one of four treatments in a completely randomized design of treatments. They were fed by basic corn-soybean diet and basic diet supplemented with 1% glutamine...
