Abstract
The present study was
conducted on 453 lactating cattle of various breed present at 21 farms. The milk
samples from these animals were collected to diagnose mastitis using California Mastitis Test (CMT). The epidemiological data related to animals and
management was collected and analysed to draw meaningful conclusions. The
results of t-test
revealed significant association between body
weight, udder depth, teat length, teat diameter (P<0.001) and lower teat end to
floor distance (P<0.01) with mastitis. The bivariate frequency analysis revealed
significant association for lactation stage (P<0.0001), teat end to floor
distance, parity, udder shape, teat shape, live body weight, teat and/or udder
pathology, use of oxytocin, feeding system and milk leakage with mastitis. The
results of logistic regression analysis revealed significant negative
association between teat length, frequency of culling and number of attendants,
while positive association between mastitis teat involved, teat diameter (apex,
mid and base), milk leakage, udder shape, pendulous udder, feeding system, udder
depth, teat shape, calf suckling, milk yield, teat and/or udder pathology and
live body weight. From the results of present it can be concluded that some risk
factors were strongly associated with mastitis in cattle.
