Systemic Meta-analysis of Mastitis Prevalence in Dairy Cattle and Goat of Bangladesh

Abstract

Bovine and caprine mastitis is a dreadful bacterial disease that drastically lowers milk production, and presently it is spreading as an endemic pathogen throughout the world, including Bangladesh. Moreover, mastitis is the main impediment to Bangladesh‘s tremendously rising milk-related industry and general livestock economy. Therefore, the aim of this study is to demonstrate the overall prevalence of clinical and sub-clinical mastitis in both dairy cows and goats. It is the foremost meta-analysis study regarding mastitis prevalence in Bangladesh and the study gathered the articles from the electronic database on the topic bovine and caprine mastitis published between January 2005 and November 2020. Finally, 33 articles were selected for estimating the overall prevalence rate of mastitis in ruminant (cow and goat) via random effect model estimation. Analyzing the result, the study found 43.0% (95% Cl: 37.0 - 50.0%) and 31.0% (95% Cl: 15.0 - 47.0%) prevalence rate in dairy cattle and goat. Statistically, the occurrence rate in Bangladesh is significantly higher than other countries. Although many studies showed the seroprevalence across different districts, this study demonstrates the aggregate incidence rates across Bangladesh as a whole. This paper may also serve as a reference point for the implementation of any control strategy of mastitis in Bangladesh.
