International Perspectives on Impacts of Reproductive Technologies for World Food Production in Asia Associated with Poultry Production

Abstract

Poultry meat and eggs are valuable sources of dietary protein in almost every country in the world. A number of breeding techniques, methods, and technology have been applied to obtain maximum production under different environmental and economic conditions. Indigenous and local breeds share 90 % of the total population of poultry in many developing countries in Asia. However, indigenous chickens are low in productivity. Many studies have found that crossbreeding of exotic with indigenous chickens resulted in birds that performed better, even superior to pure exotic chickens, with respect to body weight, egg production, survivability, fertility, hatchability, and egg quality. There are some other technologies for efficient use of male genetic resource and conservation of rare genetic make-up, namely artificial insemination and chimeric chicken, respectively. It was reported that 25 % of the world’s meat supply is derived from poultry, and the proportion is increasing rapidly. The continent of Asia produces almost one third of the world’s eggs. However, there are still many scopes to improve the production of poultry in many developing countries in Asia. Therefore, continuous research works would be essential to determine the suitable technologies for more poultry production to feed the increasing habitants on earth.
