Mineral block. My horses always have one in their pasture...The salt block only encourages drinking, while the mineral block not only encourages drinking but also gives the horse nutrients he may be missing in his diet.
I like the new ones that look like actual rocks-they are a bit pricey though, but my horses sure like them.
Really? I saw those but I was afraid to try one out. Hickory likes to scrape his teeth across the block and I don't want him to hurt his teeth or mouth on a pointy edge..I might try one if you've had good results with it though.
