Genetic and Economic Implications of Selecting for Milk Protein

Genetic and phenotypic parameters from Holsteins were used to estimate genetic and economic implications of including milk protein in the pricing system. Postulated variable market values were used to construct selection indexes with and without selection for protein content by the dairyman. Nine combinations of three fat values and three protein values along with a tenth case, where all market value was assigned to protein and fat content, were investigated.
