摘要
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(P<0.01);试验组鸡肉的水分含量均低于对照组,差异极显著(P<0.01);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(P>0.05)。
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 ）
