Abstract

The study was conducted on TsC1 and TsC2 ducks raised in Thanh Hoa province to evaluate reproductive performance of these ducks. A total of 500TsC1 and TsC2 ducks at one day of age were divided into 2 lots, each lot had 250 ducks with male/female ratio of 1/5. The results showed that: TsC1 and TsC2 ducks had high survival rate. The first laying eggs from 114 to 120 day, body weight of female at 16 weeks of age was from 1196.27 to 11214.6g/head. The average laying rate was from 64.36 to 73.00%. Egg reproductivity was from 4.51 to 5.16 egg/head/week, and feed conversion ratio was from 2.31 to 2.70 kg feed/10 eggs. The percentage of embryos egg was from 93.16 to 96.04%, hatchingrate/embryo egg was from 87.85 to 88.78%, hatching rate/ egg incubation number was from 83.18 to 85.03%; ducks type I/ hatching ducks was from 95.53 to 98.50%. In summary, TsC1 and TsC2 ducks adapt well to farming conditions in Thanh Hoa province and TsC1 ducks showed better reproductivity than TsC2 ducks.
