The production ability of Star 53 duck

Abstract

In February 2016, Thuy Phuong Poultry Research Center imported Star 53 duck’s grandparents from France’s Grimaud Freres. The results of adaptation and breeding have exhibited that the survival rate of ducks at 1-24 weeks of age reached 91.96-94.01%. Body weight at 24 weeks of age: males A reached 4006 g; females B reached 3596 g; males C reached 3473 g; females D reached 3106 g. The yield of eggs/48 weeks of laying females B reached 200.57, and that of the females D reached 249.58 eggs; the rate of having embryos (males A x femals B) reached 83.85%, and that of (males C x femals D) reached 85.94%; and the hatching rate/total embryo eggs were 88.38% and 86.12%, respectively. Star 53 duck’s parents had a survival rate at 95.0-96.5% of living up to 24 weeks of age. Body weight at 24 weeks: male AB reached 3861 g; female CD reached 3003 g. The yield of eggs/female/40 weeks of laying reached 215.97 eggs. The rate of embryos reached 89.92%, and the hatching rate/total embryo eggs reached 86.22% respectively. The commercial ABCD duck had a survival rate of the age up to 7 weeks reached 97.67%. Body weight at 7 weeks of age reached 3542 g. The percentage of carcasses and breast meat were 74.47% and 22.60%, respectively.
