Results of selecting stability filters 3 line color chicken TN1, TN2 and TN3
Stable yield selection over 3 generations from 2018 to September 2020 at Pho Yen Chicken Research Station-Thuy Phuong Poultry Research Center based on the estimated seed value using BLUP method: for The TN1 drum line was selected for body weight at 8 weeks of age, for the two hen lines TN2 and TN3 selected egg yield at 38 weeks of age with the TN1 drum line target: body weight at 8 weeks of age, chickens cocks reach 2600-2650g, hens reach 2200-2250g; the hen lines TN2: egg yield ≥178 eggs/hen/64 weeks of age; the hen line TN3: egg yield was ≥ 183 eggs/hen/64 weeks old. Results through 3 selective generations: The TN1 chicken line had a body weight of 8 weeks, roosters reached 2621.35g, hens reached 2203.86g, genetic coefficient was 0.32, genetic progress achieved in Cock is 15.40 g/generation, in hens 9.91 g/generation, egg yield/hen/64 weeks of age is 152.74, the embryo rate is 96.35-96.84%. The TN2 chicken line had 68.97 eggs/hen/38 weeks of age, the genetic coefficient was 0.12, the egg yield/64 weeks of age was 180.46, the embryo rate was 96.87-97.52%. The TN3 chicken line yielded eggs/hen/38 weeks of age reached 70.28 eggs, the genetic coefficient was 0.12, the yield of eggs/hen/64 weeks of age reached 185.12, the embryo rate was 96.72- 97.34%.
