Rumen-stable pellet coatings
US T100404 I4
Abstract
Pellets are disclosed which are adapted for oral administration to a ruminant, the pellets having a core material beneficial to ruminants postruminally, and a coating surrounding the core material which protects the core material in the rumen and releases it in the abomasum, said coating having an outer layer consisting essentially of a blend of about 55-75 parts by weight of a film-forming polymeric material containing at least one basic amino grouping and in which the nitrogen content is from 3 to 14% by weight of the total molecular weight of the polymeric material, e.g., cellulose propionate morpholinobutyrate, and about 45-25 parts by weight of a hydrophobic material such as aluminum oleate, and an inner layer consisting essentially of a blend of about 45-55 parts by weight of a film-forming polymeric material containing at least one basic amino grouping and in which the nitrogen content is from 3 to 14% by weight of the total molecular weight of the polymeric material, e.g., cellulose propionate morpholinobutyrate, and about 55-45 parts by weight of a hydrophobic material, said coating making up about 5 to about 50% of the weight of said pellet.
