This supplement is made from brewers dried yeast, ground into a fine powder for simple mixing into daily rations. It supplies B-complex vitamins, crude protein, lysine, methionine, calcium, and iron as part of a balanced feeding program for horses, ponies, and dogs. The powder is packaged in a resealable tub with a built-in scoop, with the larger side of the scoop measuring approximately one tablespoon. It is intended to be top-dressed on feed or mixed directly into a daily ration, and feed can be lightly moistened to help the powder adhere. No assembly or preparation beyond measuring and mixing is required.
