黄芪药渣对放牧肉鸡肉品质的影响

选用7日龄的岭南黄鸡80只,随机分为4组,每组20只,研究黄芪药渣对放牧条件下岭南黄鸡肉品质及屠宰率的影响。试验组饲粮中分别添加3%、4%、5%的黄芪药渣进行为期54d的饲养试验,观测岭南黄鸡肉品质指标的变化。结果表明,添加黄芪药渣的试验组鸡肉的系水力均高于对照组,差异极显著(P0.01);试验组鸡肉的水分含量均低于对照组,差异极显著(P0.01);试验组鸡肉的pH值、脂肪和蛋白质的含量与对照组相比差异均不显著(P0.05)。

Effects of Feed Additive of Astragalus Residue on Meat Quality of Grazing Broilers

The study was undertake to assess the effects of astragalus residue on meat quality and dressing percentage of Lignan yellow chicken under pastruing condition. 807 - day - old kubgbab yellow chicken were randomly divided into 4groups （20 birds in each group）, experimental diets added with 3% .4% .and 5% astragalus ,respectively ,residue were fed to brids during a 54 -d peri - od, meat quality parameters were measured. The results showel that the capable of binding water in test group was significantly higher than control group（ P 〈 0.01 ）, whereas moisture content in test group was remarkably lower than control group （P 〈 0.01 ）. There was no significant difference in pH, fat content and protein content between test and control group（ P 〉 0.05 ）
