- Abstract
Background The purpose of the study to find out the productivity, existing management system and pregnancy rate of anestrous buffalo cows following hormonal treatment protocol at the Coastal areas of Bangladesh. Methods The study was conducted during the period from August 2017 to May 2018 at Charfashion and Golachipa upazila of Bhola and Patuakhali district, respectively. A total of 101 buffalo cows' data were collected randomly by using an interview schedule as well as examination of genital system by rectal palpation. Among them, 60 anoestrus buffalo cows were selected for four treatment protocol: treatment-A (anthelmintics+vitamin), treatment-B (injection of PGF2a), treatment-C (injection of GnRH) and treatment-D (Injection of GnRH+PGF2a). Results Out of 101 buffalo cows, the calving interval, number of service required per conception, gestation length, milk yield per day, lactation length, post-partum anoestrous period, number of days of peak milk yield, total milk yield of 305 days were 379.21±7.87 days, 1.13±0.03 times, 318±0.05 days, 2.42±0.05 liters, 156.53±3.06 days, 101.98±1.06 days, 98.07±207 days and 745.89±15.46 liters, respectively. We found that the buffalo cows were reared significantly (p<0.05) in extensive system (82.18%) and 100% farmers used to feed the calf directly from its mother. The deworming, vaccination and showering of cows were not practiced properly. In case of treatment response, the estrus and pregnancy rate of treatment A, B, C and D were 20 and 13.3%, 33.3 and 20%, 40 and 26.7%, and 66.7 and 46.7%, respectively. Conclusions It may be concluded that the rearing system of buffaloes at the coastal areas of Bangladesh is not followed the scientific method, which provides bad impact on the productive and reproductive performances of buffaloes. The treatment of anoestrus buffalo cows with GnRH and PGF2a is recommended to have better oestrus and pregnancy rate.
