断奶应激对奶水牛犊牛血液生理生化指标和免疫功能的影响
Effect of Weaning Stress on Blood Physiology and Biochemistry Indexes and Immune Function in Dairy Buffalo Calves
摘要
Abstract
To study the effect of weaning stress on dairy buffalo calves,5 healthy calves were cho-sen and weaned,and the blood samples were collected at 1 day before weaning,and 1,14 and 21 days after weaning to analysis blood physiology and biochemistry indexes and immune function. The results showed that the count of white blood cell,lymphocyte,erythrocyte,monocytes and hematocrit,aspartate aminotransferase activity,blood glucose,cortisol and immunoglobulin G con-tents of dairy buffalo calves were no significant difference between before and after weaning treat-ments (P>0.05).The count of neutrophils at 21 d after weaning were significantly lower than that of 1 d before weaning of dairy buffalo calves (P<0.05).However,lactate dehydrogenase and alanine aminotransferase activity in weaned treatments were significantly higher than those of ani-mals in the treatment before weaning (P<0.05).The serum urea nitrogen of dairy buffalo calves at 21 d after weaning was significantly higher than that of 1 d before weaning (P<0.05)and he-moglobin content at 2 1 d after weaning was significantly lower than that at 1 day before weaning (P<0.05).It indicated that the physiological and immunity function of dairy buffalo calves were challenged under weaning stress.关键词
