This experiment will be aimed to analyze the inlfuences of ketosis on the data of DHI, and have been screen out warning project and its warning concentration. When the cows were ketosis, the production drawdown, lactose content decline, butter-fat percentage, protein percentage, somatic cell count were rise. By the statistical analysis, lactose was the largest affected factor. Other items would have different reaction as the different feeding. Though selected, the warning concentration of group is 4.86%, the individual is 4.68%.
