It is expected that the human population in sub Saharan Africa will experience a growth of 1.2 % per year over the next 30 years. There is therefore pressure to incr

In exploring the best ways to formulate sustainable society, it is essential to make the most of livestock products by applying appropriate reproductive technologies. There is no doubt that reproductive technologies such as AI an

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 t

Current and Future Reproductive Technologies for Avian Species, the future would require significant improvements in genetics, nutrition, and managerial practices including reproduction. This chapter summarizes some of the recent developments in ameliorating reproductive dysfunction in broiler breeder chickens, cryopreservation of avian spermatozoa, sex selection, and avian transgenesis.
