Appearance characteristics and production ability of nuclear Bau Ben duck flock
The nuclear Bau Ben duck flock has been used for 4 generations at Dai Xuyen Duck Breeding and Research Center from 2012 to 2015, the aim: to estimated Appearance characteristics and production ability of nuclear Bau Ben duck flock. The results showed that: These ducks have uniform color of feather and beak at 1 day old, 8 weeks of age and adults. The survival rate of Bau Ben ducks was high and gained of 96.08 - 97.50%. The body weight at 8 weeks of age gained 1282.3 - 1352.3 g/bird, the body weight at 21 weeks of age was 1842.5 - 1876.3 g/bird. The age of laying was 150 - 153 days old, the laying rate was 44.16 - 46.50% and the egg yield was 164.65 - 169.26 eggs/female/ 52 weeks of laying, the feed consumption was about 3.83 - 4.76 kg/10 eggs. The egg weight was about 70.34 g and Haugh unit was 90.90. The fertility rate reached to 92.06 - 95.06%, the hatching rate / fertility eggs was from 85.14 - 87.13%; the hatching rate /total incubated eggs was about 80.35 - 82.78%. The nuclear Bau Ben duck has an appearance and stable production ability for 4 generations.
