Comparison of relative net income with and without the application of opportunity cost
… and registry status on measures of profit. Relative Net Income (RNIJ) and RNI including opportunity cost (RNIOC), the revenue forfeited that could have been generated by a replacement heifer, were calculated for 48 month, 60 month, 72 month, and all lactations herdlife period. Application of …

Evaluation of optimum and near optimum pair selection methods for increasing predicted relative net income in Jersey cattle
… importance of non-linear relationships between Relative net income per day of productive life (RNI/DPL) and individual traits, 921,915 potential offspring were simulated from all possible matings of 20,487 Jersey cows and 45 active AI sires. Predicted milk yield, fat yield, and 13 linear type …

Use of sire evaluations for first, all, and later lactations to predict lifetime profit functions of individual daughters
… 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. …

The Effect of Inbreeding on Lifetime Performance of Dairy Cattle
… cows and their herdmates was used to calculate Relative Net Income adjusted for opportunity cost (RNIOC) for the 2,249,835 cows with an 84 month herdlife opportunity. The effect of inbreeding was analyzed using both a fixed and animal model, with little difference in results. Inbreeding …

Relationships among estimated net income, herdlife and linear type traits in dairy cattle
… cost of postponed replacement (OC) is the income forfeited by keeping a cow for an extra day and is estimated by the income produced by an average replacement. The effect of adjusting a measure of net income, relative net income (RNI), for OC (RNIOC) by lactation was studied. After edits, …

Estimation of the Economic Impact of a Unit Change in Predicted Transmitting Ability for Daughter Pregnancy Rate and Other Predicted Transmitting Ability in the Merit Indexes
… estimates to determine the economic value of genetic changes in traits for which genetic evaluations (predicted transmitting ability, PTA) are currently available. Data were collected from six states processed by Dairy Records Management Systems (DRMS) from herds on continuous test for at least …
