For detection of most frequent bovine diseases that adversely affect production, bulk milk samples offer several advantages over blood analysis, including ease of use and cost-effectivness. The results oJ the analysis of collective milk sample enable the nutritional and health status determination of the herd. Discussions with producers, further analyses of husbandry measures, clinical examination of animals, blood and milk samples ensure an effective health and productive management of the herd. Our findings are based on the evaluation of 1547 weekly bulk milk samples. Milk samples from four districts in Slovenia were collected weekly on 30 farms through 1993 (n= 12) I 1994 (n= 18) and analyzed for fat, protein, lactose, urea, sodium, potassium. acetone concentrations and somatic cell count. A coefficient between fat/protein and protein/urea was also  calculated. The model of multiple analyses of variance revealed that the results of milk analyses were statistically significantly (P<0,05) influenced particularly by the year of the investigation, farm, season (winter/summer ration) and to a lesser extent (P>0,05) by the health status of the udder (SCC x I 000/ml) and ketolactia. The results of the milk profile test are useful for producers as well as all specialists involved in dairy industry, with emphasis on economics and cost reduction of production.
