Abstract excerpt
Genetic variances and covariances were estimated by multiple-trait, derivative-free restricted maximum likelihood (DFREML) using an animal model for tibial dyschondroplasia (TD) expression and body weight at 4 and 7 wk of age. Data were collected from 7,483 broiler progeny obtained from 421 sires and 977 dams as part of a seven-generation selection experiment for high, and low TD expression, along with a randomly...
