Understanding Stocking Rate
Stocking rate is the number of animals grazing a given area for a specific time. It's the most important management decision a livestock producer makes — overstock and you degrade pasture, understock and you leave money on the table.
The standard unit is the Animal Unit (AU): one 1,000-lb cow with calf consuming about 780 lbs of dry forage per month. Other livestock are expressed as fractions: sheep ≈ 0.2 AU, goats ≈ 0.17 AU, horses ≈ 1.25 AU.
Carrying Capacity by Region
| Region | Forage (lbs/acre) | ~Acres per Cow |
|---|---|---|
| Southeast US | 5,000 | 2–3 |
| Midwest (tall-grass) | 4,000 | 2–4 |
| Great Plains (mixed) | 2,500 | 4–8 |
| Arid West | 1,200 | 8–15 |
| Pacific NW | 4,500 | 2–4 |
Rotational Grazing Basics
Dividing pasture into paddocks and rotating livestock through them allows each paddock rest time for regrowth. The “take half, leave half” rule (50% utilization) is the gold standard. With 8 paddocks grazed 3–4 days each, rest periods reach 21–28 days — enough for full recovery in most climates.
Frequently Asked Questions
How many cows can I run per acre?
It varies by region. In productive Southeast pasture (5,000 lbs forage/acre), about 1 cow per 2 acres. In the arid West (1,200 lbs/acre), you may need 8–10 acres per cow.
What is an Animal Unit Month (AUM)?
An AUM is the forage needed for one 1,000-lb cow with calf for one month — about 780 lbs of dry matter. Sheep are ~0.2 AU, horses ~1.25 AU.
What utilization rate should I use?
50% is the standard (“take half, leave half”). This maintains pasture health and root reserves. Going above 65% risks overgrazing.
How does rotational grazing improve capacity?
Rotational grazing can increase carrying capacity 25–50% vs. continuous grazing by allowing paddocks adequate rest for regrowth.
How many paddocks do I need?
Minimum 4, ideally 8–12. More paddocks = longer rest periods. With 8 paddocks grazed 3–4 days each, rest periods reach 21–28 days.
