At what age should I consider a senior feed?By NS KNG Admin / March 25, 2024 In general, I would consider a senior feed when you notice changes in body condition, trouble chewing, poor teeth or needing to increase grain amounts to maintain weight. A general rule of thumb is to consider changing to a senior feed when a horse is in their late teens. But if your horse is maintaining its weight, in good body condition and eating well, don’t make a change just to make a change. (Kristyn Sturken)
