Abstract/Description: | Data from 698 pigs were used to examine the potential applications of growth curve parameters as selection criteria for altering the relationship between body weight and age. A logistic growth function was found to be best fitted for modelling the growth. Estimates of asymptotic body weight (K), maximum growth rate (R) and age at point of inflection (t* ) have been obtained by nonlinear least squares. Phenotypic and genetic parameters were estimated for the estimated growth curve parameters and for body weights through 24 weeks of age. Half-sib model was used for computing genetic parameters. Estimated genetic correlations suggest that t* may be useful in selecting pigs for increased body weights at 24th week of age which is very close to slaughtering age and simultaneously for decreased mature body weight |
