Calving distribution is the percentage of calves born in each 21-day cycle throughout the calving season.
As the calving season ends and producers switch gears toward breeding season, there is an opportunity for producers to evaluate their calving distribution and the impact it has on their bottom line. Now is the time for farmers and ranchers to incorporate any changes they want during breeding season, such as when to pull their bulls from pasture, that will affect next year’s calf crop.
Each time a cow is not bred during a 21-day heat cycle, it can cost up to 39 lbs of weaning weight (assuming an average daily gain on calves of 1.85 lbs/day). Having more calves born in the first 21 days of the calving season allows producers to market larger, more uniform groups of calves and increase their profit potential.
The standard industry target is to have at least 60% of females calving within the first cycle, followed by 25% calving between 21-42 days, 10% between 42-63 days and the remaining 5% calving in the fourth and final cycle. An ideal distribution could be 70-20-10 with a condensed breeding season of three cycles (63 days). Continue reading
