Each animal has its individual salt requirements. Some want more than others… they need more for proper animal metabolism. A steer on a winter ration of roughage will require much more than a steer on a fattening ration of roughage and grain. Similarly, sheep will require more salt than other animals. A milk cow, giving off salt in every pound of milk will require more than a beef cow. To be sure, it is a good thing to mix salt with the grain ration. But additional salt should also be fed Free Choice so that each animal can help itself to the salt it needs, when and where it wants it.
