Abstract

Detection of subclinical mastitis by using the California mastitis test, at the level of the udder’s quarter. In total 10 animals were tested 56.02% of cases had positive reactions to the California mastitis test. Most common positive reaction we found in the milk was in one or two quarters with the intensity of the reaction of one and two plus. The most common causes of mastitis were staphylococci, streptococci and mixed infections. Continuing use of these methods it is possible to timely detect the presence of subclinical mastitis and get satisfactory results in the prevention and treatment of mastitis as well as increasing the quantity and improving the quality of milk.
