Hoof Nutrition Intelligence Hoof Nutrition Intelligence is a twice-a-month web segment that is designed to add to the education of footcare professionals when it comes to effectively feeding the hoof. The goal of this web-exclusive feature is to zero in on specific areas of hoof nutrition and avoid broad-based articles that simply look at the overall equine feeding situation.

Below you will find the latest question and answer installment that you can share with your footcare clients.

Q: What impact can salt and trace-mineralized salt blocks have on the health of my horses?

By J. Frank Gravlee, DVM, MS, CNS, and Scott Gravlee, DVM, CNS, Life Data Labs

A: Salt and trace minerals should not be fed in combined form, as a horse’s need for each is different. Salt requirements beyond metabolic needs are based almost entirely on the amount a horse sweats, while trace minerals are a metabolic need and are relatively steady regardless of exercise and ambient temperature.

When salt and trace minerals are fed together in block or loose form, horses are force-fed trace minerals according to their salt needs. This can become dangerous since trace minerals aren't easily shed and can rise to toxic levels in a horse’s system.

Feed a high-quality hay, a single balanced supplement and grain as needed, as most horses receive more than enough trace minerals. However, it’s generally a good idea to provide free-choice loose salt to ensure a horse’s salt needs are being met.

Salt blocks are intended for rough cattle tongues and the tongues of horses are too smooth to achieve much gain from licking. Salt-depleted salt-addicted horses may bite off a chunk and swallow it, creating an abundance of hoof-destructive urine due to excess salt-excess thirst.
