This research was carried out at Chương Mỹ and Phú Xuyên Districts for two years of 2009 – 2010 by production record keeping system according to a production cycle of 270 poultry flocks at 210 farms and smallholders to aim at better understanding the diversification, technical productivity in this region through an approach of animal production systems and the supply chains with their various constraints. Agricultural by-products are taken full advantage maximum but the daily diet is not balanced in smallholders or commercial farms. Production productivity is good with industrial broilers of ISA Brown, Ai Cập hens and Mix 1. Rate of mortality occupied about 2% with ISA Brown hens, 3% with broiler Mix 1 compared with 15% - 27% of Lương Phượng chickens, CV Super Meat, French Muscovy ducks and backyard production. Poultry production in these zones is really diversified, complex about the races, feed sources and preventive sanitation. But this poultry production is facing grave difficulties such as good quality of DOCs, large fluctuation risk of prices of inputs/outputs and the high risks with epidemic diseases from this year to another.
