Description
Protein and urea concentrations were measured weekly in bulk milk samples on a large Slovenian farm of 385 Holstein-Friesian dairy cows throughout 1993. The relationship between protein and urea concentration in bulk milk samples was presented as a coefficient which was related to changes in the diet from season to season. The protein/urea coefficient was afterwards connected with the number of inseminations and incidence of urovagina and aseptic pododermatitis (sole haemorrhages). It is concluded that a coefficient below 0.6, indicating a surplus of protein and nitrogenous substances in the diet, is unfavourable for the health status of dairy cows. Coefficient values above 0.8 indicate that the feed intake is well balanced
