The Ranch StackHow Many Cows Per Acre in Texas? Stocking Rates Explained
Updated Oct 21, 2026 · Independent guide · Not sponsored
Short answer: there is no single number for Texas. Published regional ranges run from roughly 1 cow per 1–3 acres on well-managed improved pasture in East Texas to 1 cow per 35–150 acres on native range in West Texas. Texas A&M AgriLife Extension warns against using a blanket county or regional rate, and says the right number has to be worked out for your own pasture from how much forage it grows.
Start with the animal unit
Stocking rates are stated in animal units (AU). AgriLife defines one AU as a 1,000 lb cow with or without a calf. It eats about 26 lb of forage a day, or 9,490 lb a year (26 × 365). Bigger cows count as more than one AU, so a 1,300 lb cow is about 1.3 AU, and a 1,800 lb bull is about 1.7 AU.
"Take half, leave half" really means about 25%
AgriLife explains that the old rule does not mean cattle get half the grass. Half is left standing to protect the plants and soil, and about 25% disappears to trampling, decay and insects, which leaves about 25% of yearly forage production for the cattle. Their example: at 20 acres per AU per year, each acre has to supply 475 lb of forage to the cow (9,490 ÷ 20), so it has to grow about 1,900 lb a year (475 ÷ 0.25).
The formula
Acres per cow per year = (26 lb × 365 × AU per cow) ÷ (forage lb per acre per year × 0.25)
Example: a 1,200 lb cow (1.2 AU) on pasture that grows 3,000 lb per acre needs 11,388 ÷ 750 ≈ 15 acres for a full year. On native range growing 1,000 lb per acre, the same cow needs about 46 acres. Our free stocking rate calculator does this math for you.
Only count grazeable acres
AgriLife notes cattle make limited use of slopes over 10% and of areas more than 2 miles from water, so heavy brush, steep ground and far-from-water areas should be left out before you divide. Small-acreage owners, they add, usually overestimate what their land can carry.
Typical ranges by region (rough guide only)
The Texas Landowners Association publishes these ranges. They are a starting point, not an AgriLife or NRCS recommendation:
| Region | Improved pasture | Native pasture |
|---|---|---|
| East Texas | 1 AU / 1–3 ac | 1 AU / 3–6 ac |
| Post Oak Savannah | 1 AU / 3–6 ac | 1 AU / 8–15 ac |
| South Texas Plains | 1 AU / 2.5–8 ac | 1 AU / 15–30 ac |
| Edwards Plateau | 1 AU / 2–6 ac | 1 AU / 10–60 ac |
| Panhandle | 1 AU / 2–6 ac | 1 AU / 20–50 ac |
| West Texas | n/a | 1 AU / 35–150 ac |

- Look up your soils and their expected forage production on the USDA NRCS Web Soil Survey.
- Call your county AgriLife Extension agent or local NRCS office. AgriLife says these offices have forage production guides for every county in Texas and can help you set a rate.
- Check forage in late June or early July, October and March, as AgriLife suggests, and adjust numbers in dry years instead of buying hay all summer.
