Genetic parameter estimates and expected progeny differences for mature size in Angus cattle.

Abstract excerpt

Mature size records collected on Angus cows of 5 to 12 yr of age were used to estimate heritabilities, genetic correlations, and EPD for mature weight and mature height. A total of 256 sires were evaluated using mature size data collected on 2,732 daughters. Data were analyzed using REML procedures with a two-trait sire model to estimate sire and error variances for mature weight and height. Models with and...
