At Redmond Agriculture, we understand that when your animals feel good, you feel good. That's why we offer Redmond Natural Block. Our block is made from premium natural sea salt with multiple trace minerals. We don't add any extra minerals to this block--Redmond's sea salt already naturally provides trace amounts of selenium, manganese, copper, iodine, zinc and more. This block works well for all classes of beef/dairy cattle, sheep, goats, pigs and horses.
