| Abstract/Description: | ABSTRACT Data from 698 pigs were used to examine the potential usefulness 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 to model growth through 24 weeks of age. Estimates of asymptotic body weight (K), maximum growth rate (R) and age at point of inflection (t*) have been obtained by non-linear 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 were 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 closure to slaughtering age and simultaneously for decreased mature body weight. |
