Genetic parameters of growth curve in chickens



Genetic parameters of growth curve in chickens



Proceedings of the 7th World Congress on Genetics Applied to Livestock Production, Montpellier, France, August, 2002 Session 11: 0-4



Genetic parameters of the Gompertz function were estimated on 464 slow growing chickens, regularly weighed between 4 and 16 weeks. It was shown that mean values of the initial specific growth rate (L), the maturation rate (K), the age at inflection (TI) and asymptotic body weight (A) were 0.132/day, 0.028/day, 55.1 days, and 3951 g, respectively. Males had a 3.3 % lower L, 10.1% lower K, 17 % higher TI and 55.5% higher A than females.
