【摘要】 选取西宁地区某三个奶牛场荷斯坦奶牛２３６头进行３项试验。１．检测奶牛产后血酮血糖含量变化；２．产后奶牛降酮升糖试验；３．正常泌乳牛降酮升糖试验。结果表明：奶牛产后４８～５２ｈ血酮含量较产后４ｈ内极显著升高（Ｐ＜０．００１），而血糖含量在产后５２ｈ内，每隔２４ｈ呈极显著降低（Ｐ＜０．００１）；采取降酮升糖措施后，产后奶牛及正常泌乳牛血酮含量极显著降低而血糖含量极显著升高更多还原

【Abstract】 For this study,236 Holstein cows were selected from three dairy farms in Xining area.The changes of blood ketone body and glucose collcentrations in postpartum cows were determined in experiment 1,the test about decreasing ketone body and increasing glucose levels in postpartum cows was carried out in experiment 2,and the same test as experiment 2 was corducted in the normal lactating cows(between lactation period of 2～8months)in experiment 3.The results showed as follows:the blood ketone body concentration at 50±2 h postpartum was significantly higher than that within 4 h after calving(P<0.001).The blood glucose concentrations between 2±2 h and 50±2 h after calving decreased significantly at intervals of 24 h (P<0.001).After adopting the measure to decrease the blood ketone body and to increase blood glucose levels,the blood ketone body levels decreased significantly and the blood glucose levels increased significantly in those experimental cows both in experiment 2 and 3.更多还原
