| Popis: | The aim of this study was to evaluate the presumptive factors might be responsible for repeat breeding syndrome of cows in Bangladesh. The study was conducted in different villages around the Faculty of Animal Science and Veterinary Medicine, Patuakhali Science and Technology University, Outer campus, Barisal during the period from July to September 2017. A total of 100 repeat breeder cows were evaluated considering different presumptive influencing factors such as breed, age, parity, body condition score (BCS), fetal death, retention of placenta, post-partum endometritis, abortion, dystocia and managemental practices of cows. It was found that there was no significance (p>0.05) effect of parity and age of cows on the occurrence of repeat breeding syndrome in local and crossbred cows. Repeat breeding syndrome was significantly higher in BCS 2.0 to 2.5 in local breed and 3.0 to 3.5 in crossbred cows than that of other groups. In the study animals, dystocia was 4.0%, fetal death was 58.2%, retention of placenta was 57.1%, post-partum endometritis was 4.1% in crossbred cows. Cows in semi-intensive system raring had significantly (P |
