Abstract

The physiological study was carried out to determine the relation between of risk factors and occurrence of infectious mastitis disease that associated in 453 indigenous dairy cattle in farms nearby the Tehran. Milk samples were collected for mastitis detection by California Mastitis test (CMT) .The analysis of results revealed significant association between body weight, udders depth, teats length and diameter P<0.001, and teats distance to the floor were decreased in affected cattle at Pstage, teat end distance to floor, udder shape and parity, teat shape, live body weight, teat and /or udder pathology, use of toxytocyin , feeding system and milk secretion with mastitis (P<0.0001). The results of logistic regression analysis revealed significant negative association between teat length, frequency of culling and number of attendant ,while there is a positive association between mastitis involved teat , teat diameter (apex ,mid, and base), milk secretion ,udder shape, pendulous udder, feeding system, udder depth, teat shape, sucking, milk yield, udder pathology and live body weight. According the results it is concluded that some risk factors are strongly associated with mastitis in cattle.
