Abstract
Disclosed is the feed or feed additive granular agent containing a phisiologically active substance and a coating layer having a laminar structure in which the tabular crystals are arranged in a laminated state. The coating layer comprises (a) one or more substances selected from the group consisting of a specific fatty acid or ester thereof, a specific animal or vegetable fat and fatty oil which may be hardened by hydrogenation, and a specific wax, and (b) tabular crystals of a substance which is sparingly water-soluble under a neutral condition but is readily water-soluble under an acidic condition and which has an average particle size of 5 to 30 .mu.m, wherein said coating layer is present in a coating ratio of 5% by weight or more and 50% by weight or less, wherein said first coating material and said second coating material are in a proportion of 3:2 to 1:3 by weight, and process for producing the same. The granular agent has a high mechanical strength, increased durability in the rumen and superiority in solubility and absorption of the physiologically active substance of said agent in the abomasum or downstream thereof resulting in efficient breeding, growth, or lactation o…
