Cattle Baron Master Business Plan — Herd Performance

Calving percentage, weaning rate, mortality and replacement heifer retention — the parameters that drive every projection in the plan.

The gap between calving and weaning percentage is calf mortality, and it narrows from 6.0 percentage points in Year 1 to 4.2 by Year 5. That narrowing is worth roughly a third of the total weaning improvement and it is entirely a function of supervision during the calving window — which the controlled breeding season makes practical by concentrating it into ninety days rather than spreading it across the year.
