Abstract

Disclosed are compositions comprising NPN compound coated with a bypass agent allowing ruminal bypass of the composition and a method for increasing fiber digestibility, a method for increasing feed intake, a method for increasing somatic growth, a method for increasing milk production, a method for reducing N excretion in a ruminant, a method for improving rumen pH stability in a ruminant, a method for preventing or reducing ammonia toxicity in the rumen. The compositions and methods of the invention are particularly suitable for ruminants that are held in harsh climates and/or at remote locations from a farm.

First claim

1 - 15 . (canceled)

16 . A ruminal by-pass composition, comprising
a non-protein nitrogen compound, and a rumen by-pass agent, for ruminally by-passing the non-protein nitrogen compound, wherein the rumen by-pass agent is a coating surrounding the non-protein nitrogen compound and the coating essentially consists of a hydrogenated vegetable oil, the non-protein nitrogen compound is one or more compounds selected from the group consisting of urea; ammonium salts; methylene urea, biuret, acetamide, butyramide, dicyanoamide, formamide, ethylene urea, isobutanol diurea, lactosyl urea, propionamide, uric acid and urea phosphate, a ratio of the non-protein nitrogen compound to the coating is from 83:17 to 75:25, and the ruminal by-pass composition is suitable for ingestion by a ruminant.

17 . The ruminal by-pass composition according to claim 16 ,
wherein the hydrogenated vegetable oil is selected from the group consisting of hydrogenated palm oil, soybean oil, cotton seed oil, rapeseed oil, canola oil, peanut oil, corn oil, olive oil, sunflower oil, safflower oil, coconut oil, lineseed oil, tung oil, and castor oil.

18 . The ruminal by-pass composition according to claim 16 ,
wherein the non-protein nitrogen compound is one or more compounds selected from the group consisting of ammonium acetate, ammonium sulfate, ammonium butyrate and an ammonium salt of an amino acid.

19 . The ruminal by-pass composition according to claim 16 ,
wherein the ruminal by-pass composition has an average particle size of about 1 mm to about 6 mm.

20 . A ruminal by-pass composition obtained by the process according to claim 21 .

21 . A process for preparing the ruminal by-pass composition according to claim 16 , the process comprising:
a) providing particles comprising a non-protein nitrogen compound in a drum coater, b) heating the particles of a) to a temperature in the range of from 10° C. below a lower limit of a melting range of the rumen by-pass agent to the lower limit of the melting range of the rumen by-pass agent, c) providing a molten rumen by-pass agent in a reservoir outside the drum coater, d) heating the molten rumen by-pass agent from c) to a temperature between an upper limit of the melting range of the rumen by-pass agent and 10° C. above the upper limit of the melting range of the rumen by-pass agent, e) applying the molten rumen by-pass agent from d) onto the particles of b) in a rotating drum coater, f) maintaining a temperature of a particle bed at the temperature in the melting range of the rumen by-pass agent, thereby obtaining a composition and g) cooling the composition or allowing the composition to cool down.

22 . The process according to claim 21 ,
wherein the rumen by-pass agent has a difference between the lower and the upper limit of the melting range of from 3° C. to 10° C.

23 . The process according to claim 21 ,
wherein the rumen by-pass agent essentially consists of a hydrogenated vegetable oil.

24 . The process according to claim 21 ,
wherein the rumen by-pass agent is a composition comprising hydrogenated vegetable oils and fatty acids.

25 . The process according to claim 24 ,
wherein the hydrogenated vegetable oil is selected from the group consisting of hydrogenated palm oil, soybean oil, cotton seed oil, rapeseed oil, canola oil, peanut oil, corn oil, olive oil, sunflower oil, safflower oil, coconut oil, lineseed oil, tung oil, and castor oil.

26 . The process according to claim 21 ,
wherein the non-protein nitrogen compound is one or more compounds selected from the group consisting of urea; ammonium salts; methylene urea, biuret, acetamide, butyramide, dicyanoamide, formamide, ethylene urea, isobutanol diurea, lactosyl urea, propionamide, uric acid and urea phosphate.

27 . The process according to claim 21 ,
wherein a temperature of the molten rumen by-pass agent is between ca. 50° C. and ca. 85° C.

28 . The process according to claim 21 ,
wherein a temperature of the heated particles is between 40° C. and ca. 75° C.
