Revenue Traits

                  Calving ease = more calves means more revenue.

                  200 Day Weight & 400 Day Weight EBV = more weight equals more revue.

                  Fertility (days to conception) = more weight and more calves


                  Carcass weight = worth more up to 477 kg.

                  Marbling = valued based on grid premiums

                  Eye muscle area = value as impacts yield grade


                  % Retail Product = more yield is more saleable meat

           Cost Traits

                  Cow mature size = bigger eats & costs more


                  Cow intake = more intake eats & costs more

                  Feedlot feed efficiency = more feed per kg of gain means more cost

           Some traits are not so easily characterized for $Profit. Milk, for example, is a good thing until
           you get too much. When over +25, milk EBV has a more negative effect on fertility than it has
           a positive effect on weaning weight. There are a few traits not yet included in $Profit: longevity,
           structure, and disposition. These traits are important but difficult to express in dollars.




           Feed Efficiency Explained:


           Feed:Gain: Difference in the amount of feed a bull’s progeny will consume to produce one
           kilogram of weight gain.

           Example: A -0.50 F:G EBV means this ani¬mal’s progeny will consume 1/2 kilogram less feed per
           kilogram of weight gain than would progeny of a zero F:G EBV sire.

           Feed Intake: Difference in feed con¬sumption of each of a bull’s progeny in a 112 day finishing
           period.

           Example: A steer whose sire has a -100 In¬take EBV will eat less feed in 112 days than one
           whose sire had a zero Intake EBV.
