    Beaudry, Thomas Fernand (Virginia Tech, 1986-07-14)
    Sire evaluations from first, all, and later lactations for Predicted Difference milk, fat, and dollars on 226 sires were used to predict deviated relative net income. Eleven different relative net incomes were calculated on 176,902 individual cows. Low, medium and high values were used for lifetime product value and feed price. Lifetime product value was actual milk and fat production. Individual relative net income was deviated from contemporaries in the same herd and calving in the same year of first freshening.
