Horse Pasture Management for Welfare and Health

Good pasture management is fundamental to horse welfare and health. Overgrazed, poached, or weed-dominated pasture contributes to nutritional deficiency, parasite burden, and laminitis risk.

Key Facts

Horses graze selectively, returning repeatedly to preferred areas and defecating in latrine areas — this creates overgrazing and undergrazing zones
Overgrazing short-crops grass below 5cm, reducing nutritional value and exposing soil to weed invasion
Worm larvae concentrate in the bottom 5cm of grass around fecal material — overgrazed pasture has disproportionately high larval contamination
Resting pasture paddocks for minimum 6-8 weeks breaks the development cycle of most equine gut parasites
Harrowing pasture in dry, sunny conditions kills larvae by UV exposure and desiccation
Track systems (sacrifice paddocks plus perimeter paths) allow continuous outdoor access while protecting pasture during wet weather

Welfare Considerations

Pasture condition directly affects horse welfare through several pathways: nutritional value, parasite exposure, lameness from poached surfaces, and laminitis risk from sugar-rich stressed grass. Many horse owners do not have access to adequate grazing for their horses, making the management of what is available critical. Rotational grazing, harrowing, manure removal, and sacrifice areas during wet months all contribute to pasture quality that supports horse health and welfare. Good pasture management also reduces reliance on worming treatments by interrupting the parasite lifecycle at the environmental level.

What You Can Do

Remove droppings from grazing areas at least twice weekly to reduce pasture larval contamination
Implement rotational grazing with minimum 6-week paddock rests to recover sward density
Use a sacrifice area or track system during wet weather to prevent permanent pasture destruction
Have your pasture assessed for weed content — ragwort (poisonous to horses) requires prompt removal
Consider an agronomist consultation if persistent pasture problems are affecting your horses' grazing quality
