Inactive pleasure horses have a maintenance nutritional need, which can be met with good-quality pasture. Some pleasure horses on summer pasture can be nutritionally neglected. Even grasses are not created equal and may not always meet the horse's nutritional needs. In late spring and early summer, most pastures are probably adequate for the non-performing pleasure horse. Even if the horse ridden once a week, or so, average-quality pasture should be adequate.
Horses drink lots of water.
High temperature and humidity can result in this increasing. Water consumption also is higher with performance. So, pleasure horses in summer need a clean, fresh supply of adequate water. If a horse is hot from performance, it may be advisable to restrict water intake. Otherwise, horses can have free-choice water.
