ABSTRACT
Mastitis is a major cause of economic losses in the dairy industry. The aim of the present study was to examine the overall prevalence of mastitis in Algeria using a systematic review and meta-analysis. The search strategy was performed for relevant literature published from 2002 to 2023 in English and French language. The databases included were PubMed, ScienceDirect, GoogleScholar, Scopus, Springer, Algerian national database i.e., the Scientific Information Database (pnst.cerist.). A total of 4,698 dairy cows were included in the 20 eligible studies for this meta-analysis. The prevalence of mastitis was estimated at 41% [95% CI 32-49%, PI 10-81%]. Cochran’s Q statistic was 405.5 (df = 19, p < 0.001), with I² = 95% and τ² = 0.0385, indicating substantial heterogeneity. The results indicated that there is high heterogeneity among studies for overall analysis. In conclusion, estimating prevalence of mastitis among cattle in Algeria, through meta-analysis (MAs) can provide adequate measures to control mastitis infection, Moreover, effective early diagnosis and proper medication may help our country to reduce incidence of mastitis and economic losses in dairy industry.
