Özet
In every year, Subclinical mastitis (SCM) frequently occurs and results huge economiclosses in livestock industry of Bangladesh. This study was redacted to estimate thepresent status of SCM in cow in selective area of Barisal district. For determining subclinicalmastitis, a total of 152 milk samples of clinically suspected cows were subjectedto White Side Test (WST) and Surf Field Mastitis Test (SFMT). Specifically, the milksamples of each individual cows which were positive to both WST and SFMT consideredas SCM indicating 35.52% prevalence. Other than the local breed cows, the cross bredcows showed significantly higher prevalence, is 47.06%. In consideration to agevariation, highest prevalence was observed at 5 to 7 years of age in both types wherecross breed was 54.71% and 36.67% for local breed cows. Though highest prevalencewas recorded as 34.78% in 2nd parity of local breed cows but the cross breed cowsshowed highest prevalence 54.55% in their 3rd parity. Afterward, non-pregnant cowsshowed the insignificantly higher prevalence (41.06%) than pregnant cows were 26.32%.Additionally, this study reported that the cross breed cows yielding more than 10 liters ofmilk (prevalence was 61.54%) were more prone to SCM than the others and also >5 to 10liters milk producing local breed cows (prevalence was 31.03%) were more susceptible toSCM than others. In a short, this study revealed that high milk yielding cross breed cowsare more likely to SCM after their $3rd$ calving.
