Samad Rajuk Uttara Apartment Project (RUAP), Kameni Building, 14D 305, Diyabari, Uttara-18, Dhaka, Bangladesh e-mail: [email protected] ABSTRACT 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.

The health and quality of animal is influenced by genetics, management practices, nutrition and environment. The main target of animal production includes good quality healthy animals that reach full production potential and a quality nutritious and safe food supply. Animal production is the science and art of rearing domestic animals with the subjects as animal behavior and management, genetics and breeding, reproduction, nutrition, meat science, dairy science and technology1 The production of cattle for various purposes especially dairy, beef, hides and other products which can be primarily categorized into dairy industry and beef industry. Cattle domestication and production have a long history and recognized as a most important livestock species because of their production and role in human culture. Many breeds and varieties of cattle that differ in appearance, performance and environmental adaptation are kept on all inhabited continents but the historic origin of the diverse phenotypes is not always clear. Cattle production systems integrate responsible management strategies, environmental principles and stewardship of property and economic awareness and viability whereas management strategies are uniquely linked with forage production and nutritive value, herd size, housing systems and opportunities to match forages with animal requirements for production.2 Cattle are the most common type of large domesticated ruminant livestock of the genus Bos under family Bovidae. Bos indicus and Bos taurus are the two distinct species of cattle. The B. indicus is the Indian sub- continent zebu (humped) cattle characterized by lower growth rate, smaller size, late sexual maturity, low
