Genetic parameters estimated with multitrait and linear spline-random regression models using Gelbvieh early growth data.

Journal of animal science - 1 Apr 2005

Abstract excerpt

Estimates of direct and maternal genetic parameters in beef cattle were obtained with a random regression model with a linear spline function (SFM) and were compared with those obtained by a multitrait model (MTM). Weight data of 18,900 Gelbvieh calves were used, of which 100, 75, and 17% had birth (BWT), weaning (WWT), and yearling (YWT) weights, respectively. The MTM analysis was conducted with a three-trait...
