Primary Considerations What are your objectives? Environment Weather Feed Resources Labor Resources Basic Selection Criteria Breed Age Sex (feeder dairy cattle) Weight and Condition

Slide 4

Phenotypic Priorities Muscle Condition (largeness versus trimness) Capacity and Frame Size Structural Correctness Performance Traits Weight every Day of Age Feed Efficiency Feeder Cattle Selection

Slide 5

Breeding Heifers Structural Correctness Volume and Capacity Balance and Femininity Condition and Udder Development Muscle EPDs

Expected Progeny Differences "the distinctions in execution anticipated from the posterity of one individual contrasted with the posterity of another person, inside a similar breed" Ensminger and Perry, 1997 Prediction of how the posterity will perform, NOT the individual Largest qualities are not generally best Accuracy is imperative Not tantamount between breeds, use breed midpoints
