The reproductive ability and heterosis of broodstock ducks (CT12xCT34)

Abstract

This study aims to evaluate the growth, reproduction, and heterosis advantage of broodstock ducks (CT12xCT34) from four newly selected CT1, CT2, CT3, and CT4 duck lines at Cam Binh Poultry Research Station in Thuy Phuong Poultry Research Center by commercial crossing method and random plots allocation of complete factor. The results exhibited that the body weight at 24 weeks of drake CT12 was 4288.67 g, of duck CT34 was 3323.00 g, egg productivity/duck/42 weeks of calving was 225.36 eggs, heterosis for egg productivity was 8.19%, feed consumption/10 eggs was 3.98 kg, heterosis for feed consumption/10 eggs was -5.61%, embryo rate reached 93.91%, heterosis of embryo rate was 1.24%, and the number of ducklings type 1/duck was155.84.
