Ginger Rowsey Experts say cattle producers can see profits increase when a larger percentage of cows calve in the first 30 days of the calving season. Report from University of Tennessee shows managing this reproductive benchmark can add profitability to the herd. The calving distribution of a beef cattle herd can have a significant impact on producers’ profits. A new publication from the University of Tennessee Institute of Agriculture illustrates this impact. The report, titled “Reproduction’s Impact on Beef Cattle Herd Profitability,” demonstrates how increasing the percentage of calves born in the first 30 days of a calving season can lead to increased returns for producers. Likewise, as the percentage of early season calves dropped, so did profit potential.
