A Review on Cattle Reproduction in Bangladesh

M.M. Kamal
Cattle among other livestock species available are the most versatile component in relation to existing integrated agricultural farming system in Bangladesh. About 90% of total 24.5 million cattle are of non-descript indigenous in origin along with 10% crossbred constitute national herd. Among indigenous cattle (Zebu) in different region non-descript Deshi, Pabna, Red Chittagong and North Bengal Grey are predominant. The reproductive performance of these cattle and other crossbred are poor. Indigenous Pabna cattle attain puberty relatively earlier than other types. It is found that about two services are required for conception. Average calving interval ranged from 365-536 days and average postpartum service period is ranged from 103-161 days among the indigenous and crossbred cattle. Anestrus and repeated conception failure are major causes of the reproductive inefficiencies. Higher prevalence of Brucellosis is reported although its impact in cattle reproduction and human health yet to determine.
