Abstract: In order to compare the difference of blood biochemical indexes between ketosis dairy cows and healthy dairy cows in a period of postpartum,and provide theoretical basis for prevention and control of ketosis dairy cows and veterinary clinical diagnosis and treatment.In this study,30 cows in an intensive dairy farm in Wuzhong city were selected for blood biochemical monitoring for 3 weeks.Dairy cows were divided into ketosis group and control group according to the concentration of β-hydroxybutyric acid (BHBA) which be used to compare significance.The results showed that there was no significant difference between the ketosis group and the control group on the day of calving (0 d);The concentration of BHBA in the ketosis group was extremely significantly higher than that in the control group on the 7th postnatal day (P<0.01);The concentrations of AST and T-bil were significantly higher on the 7th and 14th postnatal day (P<0.05);The concentrations of blood glucose (Glu) decreased significantly at 7th postpartum (P<0.05),and it decreased extremely significantly on the 14th postpartum (P<0.01);The concentrations of calcium (Ca) and phosphorus (P) did not show significant differences,but both were lower than the normal reference range which resulted in hypocalcemia and hypophosphatemia.It was found that the ketosis of dairy cows in this field was type Ⅱ ketosis after analysis and the high parity of ketosis cattle was 3-6 parities and the postpartum hypocalcemia,hypophosphatemia,and hypoglycemia were serious.At the same time,cow ketosis could cause hepatic dysfunction and affect cow performance.

Key words: cow ketosis; β-hydroxybutyrate; liver function; hypocalcemia; hypoglycemia
