چکیده

The current study was planned to investigate the potential risk factors and their association with mastitis in Cholistani cattle. For this purpose milk samples were collected and examined for mastitis using California Mastitis Test. The results showed an overall 21.96% prevalence of subclinical mastitis. The analysis of variance did not show significant association of tail size, live body weight, mid and base teat diameter with mastitis. The analysis of variance showed significantly higher involvement of right rear quarters. Results showed that teat length, teat end to floor distance and milk yield (P<0.001) were significantly lower in mastitic animals while teat apex diameter, parity and udder depth was significantly higher (P<0.001). The frequency analysis revealed significant association of mastitis between different groups such as age, udder depth, lactation stage, parity, teat shape, udder shape, teat lesions and live body weight (P<0.001). Bivariate logistic regression analysis indicated significant association of age, parity, lactation stage, teat shape, udder depth, teat and udder lesions, teat end to floor distance, milking technique, milk leakage and type of floor with mastitis.

Association of toll-like receptors 2 and 6 polymorphism with clinical mastitis and production traits in Holstein cattle

Mastitis is a costly disease of dairy cattle as it causes a loss in milk yield and milk quality in affected cows. Toll-like receptor (TLR) genes play a role in the host response to a variety of organisms including those inducing mastitis. In the present study, we investigated the polymorphism of TLR2, 4, 6 and 9 genes in Holstein cattle and ...
