Use of California mastitis test, somatic cells count and bacteriological findings in diagnostics of subclinical mastitis

Abstract

We have performed diagnostics of sub clinical mastitis in three different cow breeds with comparison of California mastitis test results, somatic cells count at quarter level and with bacteriological findings confirmation in order to justify their appliance in mastitis diagnostics. In total, 90 cows or 360 quarters of mammary gland have been examined. In 63.3 % of the examined cows, with different racial origin, positive reaction to California mastitis test have been established. Usually, positive reaction have been found in milk of one and two quarters, with reaction intensity of one and two plus. SSC higher than 200.000 in 1 ml is established in 60 % of cases and the most often causes of mastitis were staphylococcae, streptococcae and mixed infections. With continuous use of this methods it is possible to timely detect presence of sub clinical mastitis and so to obtain satisfactory results in prevention and therapy of mastitis, as well as improvement in amount and quality of milk.Dijagnostiku supklinickih mastitisa kod tri razlicite pasmine krava vrsili smo uporedjivanjem rezultata Kalifornija mastitis testa. broja somatskih celija na nivou cetvrti uz potvrdu bakterioloskim nalazom u cilju opravdanosti njihove primene u dijagnostici mastitisa. Ukupno je pregledano 90 krava ili 360 cetvrti mlecne zlezde. U 63.3% slucajeva pregledanih krava razlicitog pasminskog porekla utvrdjena je pozitivna reakcija na Kalifornija mastitis test. Najcesce smo pozitivnu reakciju ustanovili u mleku jedne i dve cetvrti sa intenzitetom reakcije od jednog i dva plusa. BSS veci od 200.000 u 1 ml je ustanovljen u 60% slucajeva. a najzastupljeniji uzrocnici mastitisa su bili stafilokoke. streptokoke i mesane infekcije. Kotinuiranom upotrebom ovih metoda moguce je blagovremeno otkriti prisutnost supklinickih mastitisa i tako dobiti zadovoljavajuce rezultate u prevenciji i terapiji mastitisa kao i povecanju kolicine i poboljsanju kvaliteta mleka.
