Weather-resistant mineral and protein supplement feeds, and methods of making same

摘要

A weather resistant mineral feed in the form of free-flowing granules is produced in a series of steps comprising (1) mixing a liquid binder with a relatively coarse granular feed ingredient to form damp binder coated granules, (2) while damp, the binder-coated granules are mixed with a trace mineral base mix, (3) the granules with their outer layers of trace minerals are mixed with substances which impart water-resistant sheaths thereto, and (4) dusting powder is applied to complete the formation of the trace mineral premix granules. The premix granules are mixed with coarse granular macromineral feed ingredients, iron oxide and a water-resistant coating solution to form weather-resistant mineral feed granules. The water-resistant sheathes are formed by mixing the product of step (2) with a fatty acid and depositing thereon a metal oxide with which it reacts.
