“…827 There are some differences on daily milk yield, lactation length, birth weight of calves, post-partum anestrus period and gestation length but no differences on the calving interval and number of services per conception have been reported in native cows. 827 Genotype (breeds) has a significant effect on biological efficiencies of dairy cows. 475,828 Performance of the Holstein Friesian breed and its crosses with local cows especially PV and 266 MV has been reported highest productive performance among all the investigated genetic groups in Bangladesh.…”

Background: Historical changes in the demand of animal protein sources (milk & meat) for human consumption have been largely increased due to increased growth of human population, income and urbanization in Bangladesh. Research on cattle production and management especially cattle breeding, feeds and fodders, milk production and products have contributed to increase potential production and genetic gains of cattle. A comprehensive review on the published inland research reports on cattle production, management and dairy products are lacking in literature which is required for further research for the cattle development and production. Objectives: An attempt to review on the published inland research reports on the advances in science and technology on cattle production, management and dairy products in Bangladesh Materials and Methods: A systematic literature review of research articles on cattle production, management and dairy products published between 1962 and 2020 from Bangladesh has been reviewed. A total of 1185 research articles on cattle production, management and dairy products supported with some international related articles have been reviewed and analyzed. Results: Research data on cattle production, management and dairy products are compiled from 1185 different research reports supported with some international reports. This review covers the status of cattle breeds and varieties with tabulated summary of 21 reports on draught cattle, 83 on fodder production, 97 on nutrition, feeds and feeding, 88 on trials of different feed formulations in non-dairy cattle and 68 on dairy cattle, 5 on the effects of heat stress on health and production, 39 on fattening of cattle, 27 on genetics and breeding, 75 on semen and AI, 20 on factors associated with conception rate (CR), 8 on oocyte and embryo collection, 9 on genotypes of dairy cows, 7 on management of smallholder dairy farms, 48 on milk production status of dairy cattle, 32 on economics of rearing cattle, 99 on productive and reproductive performances of cattle, 7 on estrus and pregnancy diagnosis, 7 problems of dairy farmers, 23 on preservative and adulteration of milk, 20 on constituents and methods of sweet preparation, 11 on cheese preparation, 9 on ice-cream, 56 on yoghurt, 4 on beef cattle production, 34 on birth weight, and 15 on calf rearing including calf milk replacer and calf starter. Conclusions: Data based reports are important for priority setting and targeting with mandate for cattle development and increase production. Currently, one of the biggest gaps in the inland datasets on cattle research and this review addresses this gap by bringing together in a review and highlighting some of the major findings. Cross-breeding remains an attractive option for cattle improvement because of the quick results that can be obtained by its use and the potential benefits it has farmers. This review would serve as an archive of research reports on cattle production, management and dairy products for the concerned academicians, research scientists, organizations and government for future planning for education, research and extension on cattle production.
