Managing horses on spring pastures

EmailManaging horses on spring pastures can prevent health problems.
Early spring pastures are lush in nutrients. A horse that has been stalled through the long Michigan winter may be at risk to laminitis if their forage source is abruptly switched from hay to lush spring pasture. There are management practices that can prevent or minimize problems when introducing horses to pasture in the spring.
1. Restrict the grazing time. Allow horses on the pasture for 20 minutes the first day and increase the grazing time by five minutes per day over a two-week period until they have adapted to the new feed source.
2. Feed hay immediately before horses are turned out on pasture during the adjustment period. They fill their stomachs somewhat, thus helping to prevent overeating. This practice curbs their appetite and allows them to discriminate between appropriate pasture foliage and weeds. There can be potentially toxic weeds in some pastures and, if horses are very hungry, they may not be selective about what they eat.
3. Supplement grazing with hay. If pasture foliage is sparse, supplementing with hay might be necessary to provide sufficient energy and other nutrients. This practice also helps prevent consuming weeds because under some pasture conditions the weeds outgrow other foliage.
4. Avoid grazing early spring pasture. If a horse has a history of founder, avoid grazing in the first four weeks of spring growth; then follow Rules 1 and 2 when introducing a horse to the pasture.
5. Use a grazing muzzle. If a horse that is susceptible to founder must be turned out on pasture, use a grazing muzzle to limit pasture consumption.
