Abstract
A hydrous aluminosilicate adsorbent composition in which the active adsorbent is a mixture of non-fibrous clay with non-fibrous zeolite. The composition is useful as a feed supplement in animal husbandry, and as a topical adsorbent for veterinary use. The mixture has a high capacity for adsorption of ammonium cations, and a synergistically high selectivity for their adsorption. Beneficial effects as feed supplement may arise from lowering the amount of ammonia passed to the liver from the alimentary canal.
Claims20
In a method for supplementing the diet of animals, the improvement which comprises:
- adding an effective amount of a hydrous aluminosilicate sorbent composition to animal feed, wherein said hydrous aluminosilicate sorbent composition comprises a non-fibrous, naturally-occurring clay and a non-fibrous, crystalline zeolite having a silica to alumina ratio of at least 10 and a Constraint Index of 1 to 12, and wherein said clay constitutes 5 to 95 parts by weight per 100 total parts of clay plus zeolite.
In a method of topically applying absorbent clay to animals to alleviate or cure a skin disorder, the improvement which comprises:
- substituting for said clay a hydrous aluminosilicate sorbent composition, wherein said hydrous aluminosilicate sorbent composition comprises a non-fibrous, naturally-occurring clay and a non-fibrous, crystalline zeolite having a silica to alumina ratio of at least 10 and a Constrain Index of 1 to 12, and wherein said clay constitutes 5 to 95 parts by weight per 100 total parts of clay plus zeolite.
