In February 2016, Thuy Phuong Poultry Research Center imported Star 53 grandparents from Grimaud Freres (France). The results of acclimated and propagated rearing showed that: the rate of one day raising to 24 weeks of age reached 91.96-94.01%. Body weight at 24 TT: drum (A) reached 4006 g, roof (B) reached 3596 g, drum (C) reached 3473 g and roof (D) reached 3106 g. Egg production / 48 weeks of laying (B) reached 200.57 eggs, roof (D) reached 249.58 eggs, embryo ratio (♂A x ♀B) reached 83.85%, (♂C x ♀D ) reached 85.94%, the rate of hatching / total eggs with embryos reached 88.38 and 86.12% respectively. Star ducks have parental survival rate up to 24TT reaching 95.0-96.5%, 24 TT TT body weight of the drum (AB) reaches 3861 g and the roof (CD) reaches 3003g, egg / roof yield / 40 week to reach 215.97 results. The rate of embryos reached 89.92% of the hatching / total eggs ratio reached 86.22%. The commercial ducks (ABCD) have the survival rate up to 7 TT reaching 97.67%, the body weight in 7 TT reaches 3542g, the carcass and breast meat ratio are 74.47 and 22.60%, respectively.Tháng 2/2016, Trung tâm Nghiên cứu gia cầm Thụy Phương đã nhập vịt Star 53 ông bà từ hãng Grimaud Freres (Cộng hòa Pháp).
