Identification of possible causes of repeat breeding in dairy cows at Baghabari milk shed areas, Sirajgonj, Bangladesh

Abstract

The present study was conducted at milk pocket areas Sahjadpur Upazila under Sirajgonj district and Shathia and Bera Upazila under the Pabna district, respectively. A total number of one hundred ninety (190) dairy farmers were surveyed randomly selecting twenty farmers from each village. All data collected were statistically analyzed using Univariate General Linear Model (GLM) procedure of SPSS computer program. Lack of balanced feed was the highest cause of repeat breeding claimed by about sixty (60%) percent farmers in this study. The highest incidence of RB was obtained in Local´Holstein Friesian crosses (69%) and lowest in Local´Sahiwal crosses (8%). From the study of present findings; it can be concluded that genotype, nutrient of feed, quality of semen, frequency of insemination and reproductive problems are the main possible causes for RB in the studied areas.Asian J.
