摘要/Abstract

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.

Abstract: 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(P＜0.01), thyroxine, potassium, chlorine, calcium were significantly improved(P＜0.05), aspertate aminotransferase, creatine kinase were very significantly descended(P＜0.01),pH were significantly descended(P＜0.05). The research suggests that the utilization of chitosan has obvious effect in regulating of cows′ endocrine and fluid balance during summer.

Key words: dairy cattle, summer, chitosan, biochemical indicators, heat stress
