Method for predicting cow subclinical hypocalcemia by using urine bilirubin, urine creatinine, blood TC and blood LDL-C

The invention provides a method for predicting cow subclinical hypocalcemia by using urine bilirubin, urine creatinine, blood TC and blood LDL-C. The urine bilirubin, the urine creatinine, the blood TC and the blood LDL-C are sensitive to the cow subclinical hypocalcemia, and the cow subclinical hypocalcemia is predicted by detecting the contents of the urine bilirubin, the urine creatinine, the blood TC and the blood LDL-C. It is clear that the contents of urine bilirubin, urine creatinine, blood TC and blood LDL-C are all significantly related to the subclinical hypocalcemia. Determining urine bilirubin gt; 4.3 [mu] mol/L, urine creatinine gt; 22.0 mmol/L, and blood TClt; 1.50 mmol/L or blood LDL-Clt (Low Density When the concentration is 0.61 mmol/L, it can be predicted that the dairy cow suffers from the subclinical hypocalcemia, the method can conduct non-invasive group monitoring on the incidence condition of the subclinical hypocalcemia of the dairy cow group, effective technical support is provided fo
