To best understand a horse's needs, we must look at how they live in their natural habitat. Horses in the wild may travel up to 28.3km/day (17.5miles/day) in search of food (1). Their digestive systems are designed to be constantly grazing, with wild and feral herds spending roughly half of the 24hr day grazing, while stalled horses may spend significantly less time eating due to feeding large amounts at meal times (2, 3, 4). Horses are social animals that travel in units and make up a larger herd, forming complex family-like structures (5). Any horse in a herd can initiate movement, and others will likely follow, suggesting a shared responsibility of movement (6). Stall-housed animals may acquire more injuries compared to group housed, have increased rates of colic, increased respiratory issues, and increased lameness (7). Individual housing can also increase aggression when social contact is limited (8, 9). Housing with limited access to forage can create an imbalance in the gut bacteria, which causes various abnormal behaviors (10).
That seems like a lot, so how do we help them?
