Studies on estimation of genetic parameters and selection index for hatching time body weights and body measurements in maternal lines of broiler breeders iii. effect of hatching time and body measurements on the body weight



Studies on estimation of genetic parameters and selection index for hatching time body weights and body measurements in maternal lines of broiler breeders iii. effect of hatching time and body measurements on the body weight



Korean Journal of Animal Science 31(8): 486-490



This study was conducted to study the effect of hatching time, and body measurements on the body weight by age. The shank length has major effect on the body weight at 4 weeks of age and the keel length had for the body weight at 6 and 8 weeks of age. Since the R2 values of the models were highest when the shank length, keel length and the hatching time were considered to the body weight at 6 weeks of age or when the shank length and keel length were considered, broiler breeders could be selected as early as 6 weeks of age.
