为进一步探明复合功能性氨基酸的应用效果与机理,在前期研究的基础上,本试验研究了日粮中添加复合氨基酸对断奶仔猪肝脏能量状态、游离氨基酸及相关基因表达的影响.将16头体重相近的(21±3)日龄断奶仔猪随机分为对照组和复合氨基酸组,每组8个重复.分别饲喂添加0.99％丙氨酸(与试验组等氮)和1.00％复合氨基酸(谷氨酸∶谷氨酰胺∶精氨酸∶甘氨酸∶N-乙酰半胱氨酸=5∶2∶2∶1∶0.5)的基础日粮.于试验第21天前腔静脉采血,屠宰取肝脏样品,待测.结果 表明,与对照组相比,复合氨基酸显著降低了仔猪血浆ALT和AST活性(P＜0.05);显著提高了仔猪肝脏总蛋白含量、RNA/DNA和总蛋白/DNA(P＜0.05),显著降低了仔猪...

In order to further explore the application effects and mechanism of an amino acid blend(AAB),this study investigated the effects of dietary supplementation with AAB on liver energy state,free amino acids and relative expression of related genes in weaned piglets following our previous studies.Sixteen(21±3)days old weaned piglets with similar body weight were randomly assigned to control group and AAB group,with 8 replicates per group.The diet of the control group was basal diet supplemented with 0.99%alanine(isonitrogenous control),the diet o...
