Extract

The method for establishing a selection criterion for a given selection objective is referred to as selection index methodology. Usually in the flock sheep, The first selection for lambs that substitution ewes and rams, is at three month of age. Genetic and phenotypic correlations for weight traits at different ages are high and range of those were from 0.42 to 0.94 and from 0.06 to 0.56 respectively. Thus, the aim of this study was to predict the coefficient of selection index.
