Management in the calves they sire. As an example, it helps users see whether a bull costing $30 more per calf is returning at least that much more in value. On the cost side of the equation, the CVC considers such things as purchase price, feed cost, salvage value and ultimate replacement cost. In terms of calf value, users estimate the added average dollar difference they expect from calves sired by the bull. Yes, that’s subjective, but necessarily so. What’s valuable in one herd and to what degree is unlike another. Plus, Stockton notes, “Every producer manages differently. As a result, they’ll get a different response from the same genetics.” Likewise, McGrann developed the Herd Bull Investment and Cost Analysis several years ago. It’s a decision aid that addresses comprehensive cost on one side of the ledger. On the other, expected calf revenue is based on weaning weight and price. Both of these aids serve up results such as the annual service cost per cow and per calf weaned, as well as other metrics to gauge the economic differences between bulls. “Calculated cost per calf and per hundredweight of calf weaned per cow exposed are good indicators to compare bull investments,” McGrann says. “The number of calves required to pay for the bull is a good indicator to monitor the investment.” “I think producers need to pay attention to what it costs to get a cow bred; not just bred, but the cost of getting a calf sired by that bull.” Stockton says. “With bulls representing 50% of the genetics of the program (single year, no replacements), you cannot afford to give up genetic progress in your herd at the expense of cheap bulls that don’t match or advance your production goals,” Gunn says.
