Match animal numbers to your land
Overstocking causes mud, parasites, erosion and water pollution. Size your herd or flock to what your pasture can actually feed.
How
- Map grazeable area from your site survey, excluding steep, wet and wooded land.
- Use animal units (AU, 1 AU is about 450 kg or 1,000 lb live weight) as a planning tool. One extension example treats 1 horse or beef cow, 5 to 10 sheep or goats, or 250 laying hens as about 1 AU.
- That same source (north-east USA) suggests 1 to 2 acres (0.4 to 0.8 ha) per AU per year. Drier climates need far more land: get a local figure from your extension or agriculture office.
- Social species need company: welfare frameworks list company of their own kind as a basic need, so plan at least two of any herd or flock species.
- Keep a margin. Start below your calculated capacity and grow only if pasture stays covered.
