How Much Salt Does a Horse Need Per Day?

By Horse Salt Supply editorial team · Updated 25 October 2026

Daily salt needs vary with body weight, diet, weather and work. Penn State Extension gives approximately 1 ounce per day as an added loose-salt example for a roughly 1,100 lb horse. That is about 28.35 g, commonly rounded to 28–30 g. It is a starting point for discussion, not a universal prescription.

What should you count before adding salt?

Record the horse’s approximate weight, feeds, supplements, turnout and exercise. List every product that already contains salt or other minerals, including a lick shared in a field. A bag label’s serving information is more useful than an assumed scoop size. Take that record to your veterinarian or qualified equine nutritionist when deciding how the overall ration should be managed.

Do not use a shop listing or block size to calculate a daily dose. A 7.7 lb per-block label describes each block; multiply it by 2, 4, 8 or 12 to calculate the selected pack’s total weight. It does not describe what one horse eats in a day.

How can I track block use?

Weigh the block at the start and after a recorded interval. Note rain exposure, broken pieces and whether other animals use it. Divide the weight loss by the number of days as a practical record of disappearance. Keep the original observations: the arithmetic cannot distinguish licking from weather loss.

If several horses share a block, a group average cannot show which horse consumed how much. Track each animal’s feeding plan separately with professional advice.

When should I review the plan?

Review the ration when work, sweating, weather or feed changes, and ask your veterinarian about an individual horse’s health or drinking concerns. Keep fresh drinking water available. Salt intake and balanced electrolyte replacement are related questions, but the same product is not automatically suited to every situation.

Which product information helps with ordering?

After choosing the feeding approach, compare net weight, physical format and the complete delivered cost. A hanging lick needs a safe fixing. A refill needs the specified holder. Loose salt is weighed and offered differently from a solid block. Choose the format for the actual setup.
