Derivation of improvement lags in a livestock industry
Published online by Cambridge University Press: 02 September 2010
Abstract
A simple and general procedure for calculating the equilibrium improvement lag in a livestock dissemination system is presented. The lag is conveniently measured in terms of the number of years of genetic change that it represents, and depends on the age and on the genetic superiority of the parents used in each step of the dissemination system. The total lag is the sum of the lags in all steps, weighting each step by the proportion of genes going through it.
