摘要
研究壳聚糖对夏季奶牛血液生化指标的影响.选择30头中国荷斯坦奶牛,随机分为处理组和对照组(每组各15头),进行添加剂饲喂对比试验.结果表明:添加壳聚糖后,奶牛血液的皮质醇、磷、葡萄糖显著提高(P<0.01),甲状腺素、钾、氯、钙显著提高(P<0.05),谷草转氨酶、肌酸激酶显著下降(P<0.01)、pH值显著下降(P<0.05).说明壳聚糖对夏季奶牛的内分泌和体液平衡的调节有明显效果.
To study the effects of chitosan on biochemical indicators in cows′ blood during summer.30 Chinese-Holstein dairy cows were randomly divided into treatment group and control group,each group had 15 cows.Took additives feeding contrast experiment.The result showed that：after adding chitosan,cortisol,P,glucose in cows′ blood were very significantly improved（P0.01）,thyroxine,potassium,chlorine,calcium were significantly improved（P0.05）,aspertate aminotransferase,creatine kinase were very significantly descended（P0.01）,pH were significantly descended（P0.05）.The research suggests that the utilization of chitosan has obvious effect in regulating of cows′ endocrine and fluid balance during summer.
