Studied was the bilirubin equilibrium in 62 normal cows, 52 cows with clinical ketosis, 31 cows with diffuse liver injury, and 14 cows that went off food for five days. A moderate rise of the total bilirubin of mixed type was found in ketosis-affected cows. Statistically significant proved the changes in the free fraction, however, there were no persuasive data that they were due to superproduction of bilirubin. Changes in the total bilirubin similar to those in cows with ketosis were established also in cows subjected to starvation, substantiated by the adequate rise of the free and the bound fraction. The hyperbilirubinemia in cows with diffuse liver injuries was found to be of a mixed type, with a very clear transposition in the bilirubin fractions. The direct: indirect ratio of bilirubin in this case was higher than unit, and the percent participation of the indirect fraction was brought down to 42.5. Apparently, the symptoms of liver affections were beyond the frames of what was found in the cows with ketosis. With the use of tests for the demonstration of urobilin and urobilinogen in the urine no dependable idea could be found of the status of the pigment fraction in the liver of ketosis-affected cows or the fact that this fraction was involved to a considerable extent. Discussed is the possibility of linking the state of hyperbilirubinemia in cows with ketosis with some energy deficiency with regard to the plasma glucosis and the liver glycogen.

A rapid method for quantitative determination of concentration of urobilinoids of fresh urine was developed. The method is based upon extraction of urinary urobilinoids using a mixture of acetic acid and ether and followed by the extraction of the ethereal phase with Ehrlich reagent and a solution of sodium acetate. Readings of absorbance from the absorption band of reaction products from urobilinoids and Ehrlich reagent are done. Performance of the rapid method: 2 ml urine + 10 ml ether + 2 ml acetic acid were thoroughly mixed for about 15 seconds. The ethereal extract was shaken after addition of 12 ml Ehrlich-reagent for 1 minute and 15 ml half-saturated sodium acetate solution were added. 0-3 minutes afterwards reading of absorption at 560 nm respectively filter Hg 578 nm. Photometer:mg/dl=29 X A578 nm, 1 cm -0,4. Spectrophotometer:mg/dl urobilinoids=13,7 X A560 nm X 1/d -0,22 (d=optical pathway). Photometrical determination of concentration of urobilinoid can also be done using table 1. Accuracy, reproducibility and specificity are fully satisfying for clinical use of the method.
