This study was carried out to determine the prevalence of anestrus problems in dairy cows associated with managemental factors such as housing system, feed quality, deworming and health management of dairy cows. Data were collected by interviewing the owner of the cows using questionnaires from selected private dairy farms and Rajshahi Dairy and Cattle Improvement Farm (RDCIF) at Rajshahi district during the period from January 2016 to December 2016. A total of 500 dairy cows were surveyed to find out the prevalence of anestrus problems in relation to housing system,feed quality,deworming and health management of cows. The raw data were then sorted, computed, coded and statistically analyzed with the help of latest version of SPSS statistics software package. Our findings revealed that, the overall prevalence of anestrus in cows was 40.2%. The housing system, feed quality, deworming and health management of cows influenced the prevalence of anestrus in cows. The prevalence of anestrus was the highest in poor housing system (45.16%) and the lowest in good housing system (36.17%). The prevalence of anestrus was not significantly (P>0.05) influenced by the housing systems. Good quality of feed showed the lowest occurrence of anestrus problems (28.82%) and poor quality of feed showed the highest occurrence of anestrus problems (78.72%). The prevalence of anestrus in dairy cows was significantly (P<0.05) influenced by the feed quality of cows. It was observed that the incidence of anestrus was higher in no deworming measure of farm (56.96%) and lower was in regular deworming measure of farm (29.64%). The prevalence of anestrus was higher in no preventive measure of dairy cows (50.95%) and lower was in regular preventive measure of dairy cows (29.92%). Deworming and preventive measures had also significant (P<0.05) effect on anestrus problems in dairy cows.
