Rumen and other stomach chamber bypass nutrients and methods of fabrication

Abstract

A stomach chamber bypass nutrient comprises a beadlet fabricated in two steps having two regions, a first region having the desired nutrient and a second region including fats and calcium based compounds. The nutrient includes lysine, methionine, .[.tryptothane.]. .Iadd.tryptophane.Iaddend., protein .[.harmones.]. .Iadd.hormones.Iaddend., vitamins and other nutrients in amounts of from 36% to 59%. The nutrient is fabricated by forming in a first step the nutrient in a beadlet form, and in a second step coating the nutrient beadlet with the second region.

I claim: 
     
       1. A stomach chamber by-pass beadlet comprising: a. first core portion being in an amount of .[.from 36% to 59%.]. .Iadd.more than 40% .Iaddend.by weight of the total weight of said by-pass beadlet comprising at least one active ingredient digestible in a stomach chamber and selected from the group consisting of animo acids, fats, peptides, hormones, medicaments, vitamins, microorganisms, minerals, enzymes and combinations thereof; and,   b. a second coating portion substantially surrounding and coating said first core portion and which is substantially indigestible in a first ruminant stomach chamber but substantially digestible in a stomach chamber and intestines after said first stomach chamber comprising at least one fatty acid selected from the group consisting of stearic acid, palmitic acid and combinations thereof.   
     
     
       2. The beadlet of claim 1 wherein said nutrient is in the form of a beadlet having the size of from approximately one-half millimeter diameter to approximately two millimeters diameter. 
     
     
       3. The beadlet of claim 1 wherein said second portion further comprises at least one calcium phosphate. 
     
     
       4. The beadlet of claim 3 wherein said calcium phosphate is present in an amount of from 0.1% to 5% by weight of the total weight of the by-pass nutrient. 
     
     
       5. The beadlet of claim 1 wherein said fatty acid of said second portion comprises at least 20% by weight palmitic acid. 
     
     
       6. The beadlet of claim 5 wherein said fatty acid further comprises approximately from 10% to 80% by weight stearic acid. 
     
     
       7. The beadlet of claim 5 wherein said fatty acid further comprises approximately from 10% to 60% by weight oleic acid and linoleic acid. 
     
     
       8. The beadlet of claim 1 wherein said first portion comprises from 40% to .Badd..[.60% 173 .Baddend. .Iadd.59% .Iaddend.by weight of said by-pass nutrient. 
     
     
       9. The beadlet of claim 8 further comprising in said first core portion an inert starter, and wherein the said at least one active ingredient digestible in a stomach chamber comprises from 60% to 98% by weight of said first core portion. 
     
     
       10. The beadlet of claim 1 wherein said animo acids are selected from the group consisting of lysine, methionine, tryptophane and combinations thereof. 
     
     
       11. The beadlet of claim 1 wherein said hormones are selected from the group selected from the group consisting of .[.bovine-somatotrophin.]. .Iadd.bovine-somatotropin.Iaddend., progesterone and growth hormones. 
     
     
       12. A stomach chamber by-pass beadlet having a coated core, the core of said beadlet having an approximately beadlet shape and comprising at least one material digestible in a stomach chamber and selected from the group consisting of animo acids, fats, peptides, hormones, medicaments, vitamins, micro-organisms, minerals, enzymes and combinations thereof in an amount .[.from 36% to 59%.]. .Iadd.from 40% to 59% .Iaddend.by weight of the by-pass beadlet, said core having a coating substantially surrounding said core, said coating being substantially indigestible .Iadd.in .Iaddend.in a first ruminant stomach chamber but substantially digestible in a later stomach chamber and intestines, said coating comprising at least one fatty acid selected from the group consisting of stearic acid and palmitic .Iadd.acid .Iaddend.and combinations thereof, said beadlet having a specific gravity of approximately from 0.8 to 1.2. 
     
     
       13. A stomach chamber by-pass beadlet having a coated core comprising: a. the core of said beadlet having an approximately beadlet shape and comprising at least one material digestible in a stomach chamber and selected from the group consisting of animo acids, fats, peptides, hormones, medicaments, vitamins, micro-organisms, minerals, enzymes and combinations thereof in an amount of from .Badd.36% to 59%.]..Baddend. .Iadd.more than 40% .Iaddend.by weight of the by-pass beadlet; and,   b. said core having a coating substantially surrounding said core, said coating being substantially indigestible in a first stomach chamber but substantially digestible in a later stomach chamber and intestines, said coating comprising at least one fatty acid selected from the group consisting of stearic acid and palmitic acid and combinations thereof, said beadlet having a diameter of approximately from one-half to two millimeters.   
     
     
       14. The beadlet of claim 12 wherein said beadlet has a specific gravity of approximately one.
