Patent claims

Composition for feeding a ruminant comprising

a) a core comprising or consisting of a biologically active ingredient selected from the list consisting of i) amino acids, derivatives of amino acids, and/or salts of amino acids and/or of their derivatives, ii) proteins, iii) peptides, iv) carbohydrates, v) vitamins, and substances having similar functions, vi) probiotic microorganisms, vii) prebiotic foods, viii) choline and salts and/or derivatives thereof, and ix) polyunsaturated fatty acids (PUFAs), and salts and/or derivatives thereof, and b) a coating surrounding said core, wherein said coating comprises one or more layers of a mixture comprising a saturated fat, and a fatty acid, and said coating comprises from 60 wt.-% +/- 10% to 80 wt.-% +/- 10% of the saturated fat and from 20 wt.-% +/- 10% to 40 wt.-% +/- 10% of the fatty acid, each based on the total weight of the coating, wherein the composition comprises from 5 wt.-% +/- 10% to 30 wt.-% +/- 10% of the coating, based on the total weight of the composition.

Composition according to claim 1 , wherein the coating comprises from 70 wt.-% +/- 10% to 80 wt.-% +/- 10% of a saturated fat and from 20 wt.-% +/- 10% to 30 wt.-% +/- 10% of a fatty acid.

Composition according to claim 1 or 2, comprising from 20 wt.-% +/- 10% to 30 wt.-% +/- 10% of the coating, based on the total weight of the composition.

Composition according to any of claims 1 to 3, wherein the saturated fat comprises or consists of a hydrogenated fat.

Composition according to claim 4, wherein the hydrogenated fat is a hydrogenated vegetable oil.

Composition according to claims 4 or 5, wherein the hydrogenated fat comprises or consists of hydrogenated palm oil, hydrogenated soybean oil and/or hydrogenated rapeseed oil.

Composition according to any of claims 1 to 6, wherein the fatty acid comprises or consists of a CM to C22 carboxylic acid.

8. Composition according to any of claims 1 to 7, wherein the fatty acid comprises or consists of a C16 to C20 carboxylic acid.

Composition according to any of claims 1 to 8, wherein the fatty acid comprises or consists of a saturated fatty acid.

Composition according to any of claims 1 to 9, wherein the fatty acid comprises or consists of an optionally substituted palmitic acid, oleic acid, and/or stearic acid.

Composition according to any of claims 1 to 10, wherein the coating comprises at least two layers, wherein each of the layers has a different composition of the coating mixture.

Composition according to any of claims 1 to 1 1 , wherein the first layer surrounding the biologically active ingredient has a higher amount of the fatty acid than the second or any further layer surrounding the first or any preceding layer.

Process for the preparation of a composition according to any of claims 1 to 12, comprising the steps of

a) providing particles containing or consisting of a biologically active ingredient selected from the list consisting of i) amino acids, derivatives of amino acids, and/or salts of amino acids and/or of their derivatives, ii) proteins, iii) peptides, iv) carbohydrates, v) vitamins, and substances having similar functions, vi) probiotic microorganisms, vii) prebiotic foods, viii) choline and salts and/or derivatives thereof, and ix) polyunsaturated fatty acids (PUFAs), and salts and/or derivatives thereof in a drum coater,

b) providing a mixture comprising from 60 wt.-% +/- 10% to 80 wt.-% +/- 10% of the saturated fat and from 20 wt.-% +/- 10% to 40 wt.-% +/- 10% of the fatty acid, each based on the total weight of the mixture, in a reservoir outside the drum coater, c) heating the particles of step a) to a temperature in the range of from 20°C below the lower melting point of the mixture of step b) to the upper melting point of the mixture of step b),

d) heating the mixture of step b) to a temperature in the range of from its upper melting point to 20°C above its upper melting point,

e) applying the heated mixture of step d) onto the particles of step c) in a rotating drum coater,

f) maintaining the temperature of the bed of particles obtained in step e) at a temperature in the range of from 20°C below the lower melting point of the mixture of step b) to the lower melting point of the mixture of step b), and

g) cooling the composition obtained from step f) or allowing the composition obtained from step f) to cool down,

wherein the steps c) to f) or c) to g) are repeated with the composition obtained from step f) or g), if the composition to be prepared has two or more layers.

Feed, feed material, premix of feed additive for feeding a ruminant comprising a composition according to any of claims 1 to 12.

Method of supplementing the diet of a ruminant with a biologically active ingredient, comprising the step of providing the ruminant with a composition according to any of claims 1 to 12 and/or with a feed, feed material, premix of fed additive according to claim 14.
