I am worried about my mare's salt consumption. She never seemed to use the fifty pound mineral block provided by the boarding stable (they are in the stalls and not out in the pasture since the amount of rain we get in the Pacific Northwest washes them away pretty fast) so I bought a Himalayan Rock and she doesn't seem to bother with that much either. I always assumed they would use it when they need it but should I add loose salt to her beet pulp each night? If so, how much should I add per day? I am just starting her on the Magnesium chloride, I am adding that to her feed and hoping she will find it palatable and not turn it down.
