Nam Mong, a duck breeder farm owner in Long An province in South Vietnam, has kept his breeding business for over three decades. He sells Peking broiler ducklings while developing his own dual-purpose layer breeder stock. He has continuously improved the genetics of his Peking drake by obtaining the parent stock from the Vigova -Southern Livestock Research and Advanced Technology Transfer Centre.Long An, located 50 kilometres south of Ho Chi Minh city, is a vast rice basin with an abundant water resource, making it an ideal site for free grazing. As a result, small hatcheries are almost everywhere in Long An. Some hatcheries are running their own breeder farms while some opt to buy hatching eggs.Dual-purpose breeder
There is a segment in South Vietnam that prefers dual-purpose duck because of sizable egg weight and acceptable bodyweight at depletion, while customers in the north and central areas prefer single purpose, either layer or meat-type duck.Nam has developed his medium-frame dual-propose duck, which yields a good egg number while the bodyweight at depletion is 3 kg close to the broiler duck. He uses the Khaki Campbell female to cross with the white feather Peking drake. Currently he is working on the 3rd generation and the selection is still ongoing. The selection is based on feather colour and body frame, which should not be too heavy like the Peking duck. The bodyweight of the female at the beginning of lay is capped at 3 kg, larger female ducks will not be selected for the breeding programme. If the progeny is too close to the Peking, the egg number will be fewer and also the egg laying period will be shorter. The Khaki Campbell is chosen because it yields over 300 eggs/duck/year with egg size varying between 65-75 grams.
