What happens when we change the assumptions? That was really the point of last week's Cow Math.
We built two hypothetical 200-cow herds with different feed requirements, calving assistance, calf survival and cow longevity, and then asked one question:
How much additional weaning weight would the higher-input herd need to pay for those differences?
Under the assumptions we used, the answer was about 73 lb per calf. That doesn't mean every higher-performing herd needs 73 extra pounds. And it certainly doesn't mean smaller cows are automatically more profitable.
Your cattle may eat differently. Your assistance rate may be lower. Your bigger cows may last longer. Your calves may bring more per pound. Change any of those numbers and the answer changes.
That's the point of Cow Math.
Take the assumptions. Question them. Replace them with the numbers from your own herd.
Because I'm a lot less interested in telling people what kind of cattle they should raise than I am in getting us to ask whether our own numbers support why we're raising them that way.
