Cattle Stocking Rate Calculator

Estimate carrying capacity from grazable acres, forage production, utilization, grazing period, and animal-unit equivalent.

How Many Cows Per Acre Can Texas Land Support?

There is no defensible statewide cows-per-acre number. Texas A&M AgriLife notes that every property is unique and that soils, topography, vegetation, usable acreage, and management all affect carrying capacity.

This calculator uses a forage budget instead: grazable acres multiplied by annual forage production and a conservative utilization rate, divided by the selected animal-unit demand and grazing period. Verify the inputs with a local Texas A&M AgriLife Extension or USDA NRCS professional before setting a stocking plan, and reduce livestock promptly when forage or rainfall declines.

Management Check

Conservative native-range planning commonly starts near 25% consumed forage.

1. Forage Supply

Grazable acres multiplied by annual dry-matter forage production.

2. Usable Forage

Supply adjusted by the utilization target and extra drought reserve.

3. Animal Demand

One animal unit is modeled as 26 lb of dry matter per day, or 780 lb per AUM.

Why the Estimate Changed

County averages are too blunt for a stocking decision. Two ranches in the same county can have different forage production because of soil depth, rainfall, brush, water distribution, grazing history, fertility, and wildlife pressure.

This calculator uses the standard forage supply and animal-unit demand approach:(acres x lb DM/ac x utilization% x drought reserve factor) / 780 lb AUM / (animal unit equivalent x grazing months)

Treat the result as a starting point. Before buying or adding cattle, verify forage production and stocking pressure with local Extension, NRCS, and on-ranch monitoring.
