Meta-analysis and meta-regression of subclinical mastitis prevalences in dairy cattle in Türkiye

Abstract

In this study, it was aimed to determine the prevalence of subclinical mastitis obtained from 38 studies conducted in Türkiye between 1988 and 2019 by meta-analysis method and to calculate common prevalence. The estimated prevalence of subclinical mastitis in the studies were evaluated separately as cow-based (11182 cows in 37 studies) and udder quarter-based (48990 udder quarters in 33 studies). According to the results, the common prevalence of subclinical mastitis was calculated as 0.48 (95% CI: 0.41-0.56) in cow-based studies and 0.32 (95% CI: 0.26-0.37) in quarter based-based studies. As a result of this study, the results of individual studies on the prevalence of subclinical mastitis in dairy cows in Türkiye were combined with the meta-analysis method and a more precise estimate of the prevalence was obtained.
