Abstract
Buffaloes play an important role in the dairy industry as the second largest source of milk supply in the world. However, their health and productivity can be significantly affected by diseases such as subclinical mastitis (SCM). SCM contributes to financial losses among farmers due to problems such as reduced milk quality and quantity, discarded milk, and treatment costs. This cross-sectional study was carried out to estimate the buffalo-level and quarter-level prevalence of SCM in dairy buffaloes and to determine the associated risk factors. The study was performed at six semi-intensively managed dairy buffalo farms located in Selangor over a period of two weeks. Lactating buffaloes that showed no systemic signs and no abnormalities of the udder and milk were selected to participate in the study. A total of 46 buffaloes from six farms were sampled. Milk samples from 184 quarters from 46 buffaloes were subjected to California Mastitis Test (CMT) for the detection of SCM. Buffalo and quarter-level risk factors were measured using questionnaires and through on-farm observations. The study recorded 39.13% and 26.09% SCM prevalence at buffalo-level and quarter-level respectively. The Chi-square analysis of buffalo-level risk factors revealed statistically significant differences (p < 0.05) in the prevalence of SCM and lactation stage. Buffaloes in the later lactation stage (more than 3 months to 6 months) had a higher risk of being tested positive for SCM compared to buffaloes in the early lactation stage (less than 3 months). Meanwhile, other factors such as age, breed, udder symmetry and average daily milk yield showed no significant association with SCM. In binary logistic regression, the quarter-level risk factors which were quarter position and teat shape, both had no significant association with SCM. In conclusion, the findings of this study can be useful in recommending and developing future control and intervention strategies to reduce the occurrence of SCM in buffaloes in Malaysia.
