SUMMARY The aim of this investigation was to study the genetic parameters of sexual dimorphism for body weight at 4 , 6 and 8 weeks of age for two strains : Dokki 4 and White Plyn:outh Rock. The estimates of heritabilities of sex differences in body weight from sire component of variance at different ages ranged from-0.20 to 0. 0 6. These estimates suggest… (More)
SUMMARY The interactions « sex X Sire families » and a sex x dam within Sire families » in two strains of chickens, Dokki-4 and White Plymouth Rock, were studied for body weight at 6 and 8 weeks of age. The results showed that Sire x sex interactions were not significant (P > 0. 05) in all cases, but dam families within Sire x sex interactions were… (More)
