In the present study, pooled prevalence of subclinical mastitis [SCM], clinical mastitis [CM] and major bacterial pathogens viz., Staphylococcus species, Streptococcus species and Escherichia coli in dairy animals was studied by using meta-analysis. Based on systematic review of studies on mastitis from 2005-2016 using online and offline databases, meta-analysis was done. Meta-analysis of 43 and 22 studies on SCM and CM, respectively was carried out with random effects model using Metaprop package in R-Software. The pooled prevalence of SCM and CM were 41% [33-49%] and 27% [19-37%], obtained by using 25,455 and 6,978 dairy animals. Pooled prevalence estimate of Staphylococcus sp., Streptococcus sp. and Escherichia coli were 45%, 13% and 14%, respectively. Period-wise analysis revealed prevalence of SCM, Staphylococcus sp., increased and CM, E. coli prevalence decreased indicating the importance of SCM and Staphylococcus species in mastitis. Zone-wise estimates for SCM and CM were high in South and North zone, respectively. The prevalence of subclinical and Staphylococcus species mastitis was high, which may cause low productivity in dairy cattle and economic loss to dairy farmers. Hence, there is a need to reduce the prevalence of subclinical and clinical mastitis by adopting scientific management, feeding and therapeutic measures for better economy of the dairy farmers.
