Assessment of production capacity of three combinations of hybrid chickens.

Abstract

The research was conducted at the Pho Yen Chicken Research Station, Thuy Phuong Poultry Research Center, from January 2019 to August 2020 to evaluate the productive ability of the combinations of hybrid parent hens (♂TN1 x ♀TN2, ♂TN1 x ♀TN3, ♂TN1 x ♀TN32) and commercial chicken TN12, TN13, TN132. The results achieved: 3 parent hen hybrid combinations (♂TN1 x ♀TN2, ♂TN1 x ♀TN3, ♂TN1 x ♀TN32) have the egg yield/hen/68 weeks of age and feed consumption/10 eggs are 191.74 eggs and 2.30 kg; 196.32 eggs and 2.27 kg; 198.78 eggs and 2.25 kg respectively. The rate of embryo reaches 97.43, 97.07, and 97.67%. The commercial chickens TN12, TN13, TN132 have the body weight at 8 weeks of age and feed consumption/kg body weight gain are 2440.07 and 2.29 kg; 2360.12 and 2.26 kg; and 2407.15 g and 2.22 kg respectively.
