reproductive performance in the period of 20-52 weeks of age. Experimental ducks were reared by intensive fanning. The ducks are stocked in tbe pond during the day and locked up at night with a density of 5 heads/m- of duckhouse and 3 heads/m^ of pond. During the experiment, ducks were fed industrial food with ME level of 2,800 kcal and CP of 19%. Ducks are raised for according to the semi-intensive farming issued by the Ministry of Agriculture and Rural Development. The study results show that although the Asia mallard are wild duck breeds, but they adapt well to intensive farming conditions on ponds, lakes. The survival rate on the reproductive stage (20-52 week of age) reaches 100%, age at 1"' egg (160.66 days), maximum production peak (86.87%) at 35.67 weeks; egg production after 52 weeks of age reached 130.12 egg /female duck with egg weight (55.69g), feed consumption ratio/lO eggs was 1.35kg. The egg quality of Asia mallard is quite good, the yolk rate (38.51%) and the shell rate (17.76%) is higher than that of other domestic duck breeds. The rate of eggs incubated (89.67), the hatching rate/eggs incubated (97.36%) the rate of first class duckling/
eggs incubated reached 85.12%.
