Good feed for a thin older horse?

Hello! Even with ad-lib forage, the nutritional value of the hay may not be enough to maintain condition.

Lucerne (chaff or pellets, and soak the pellets first) makes a good addition.

Keep in mind that a horse we read as underweight (a body condition score below 5), where the ribs show for example, is not necessarily unwell. Few people react to a horse carrying the equivalent excess weight (a body condition score of 6 or more), even though that does carry a real risk of disease and overload injuries.

If the horse has suddenly lost a lot of weight with no obvious explanation, always consult a vet, as the cause may be the teeth or an underlying illness.
