ABSTRACT:
A composition for coating a biologically active substance which is stable in a medium in which the pH is greater than or equal to 5 and which permits the release of the active substance in a medium in which the pH is less than or equal to 3.5, comprises a film-forming, water-insoluble binder which possesses controlled hydrophilicity and is optionally slightly sensitive to pH variations, and a substance which is sensitive to pH variations (e.g. an inorganic filler, simple aminated substance, basic polymer or copolymer, chitosan). Pellets for feeding to ruminants consist of a core containing the biologically active substance, e.g. methionine or lysine, coated with this substance.
