Abstract
Abstract Materials such as medicaments and nutrients that decompose when they are fed orally to ruminants because of their instability in the in vivo rumen environment can be protected from the ruminant environment by effectively coating such materials with special nitrogen-containing cellulosic materials having the ability to resist being degraded in the rumen, but also having the additional ability to dissolve in the in vivo abomasal fluid.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
30 words
A rumen-stable composition as in claim 1, wherein said composition also contains an amount of antioxidant; said amount being effective to inhibit the spontaneous degradation of said cellulose propionate 3-morpholinobutyrate.
Claim 2
Dependent Claim
41 words
A rumen-stable composition as in claim 2, wherein said composition contains at least about 10 weight percent of said cellulose propionate 3-morpholinobutyrate, based on the combined weight of (a) and (b), and (a) and (b) are uniformly admixed in said composition.
Claim 3
Dependent Claim
25 words
A rumen-stable composition as in claim 3, wherein said cellulose propionate 3-morpholinobutyrate has a composition that falls within the area designated A in the drawing.
Claim 4
Dependent Claim
41 words
A rumen-stable composition as in claim 2, wherein said cellulose propionate 3-morpholinobutyrate contains from about 13 to about 30 weight percent propionyl, from about 22 to about 50 weight percent morpholinobutyryl, and from about 0 to about 4 weight percent hydroxyl.
Claim 5
Dependent Claim
15 words
A rumen-stable medicament composition as in claim 5, wherein said other medicament is an antibiotic.
Claim 6
Dependent Claim
13 words
A rumen-stable medicament composition as in claim 6, wherein said antibiotic is chloramphenicol.
Claim 7
Dependent Claim
13 words
A rumen-stable medicament composition as in claim 6, wherein said antibiotic is chlortetracycline.
Claim 8
Dependent Claim
13 words
A rumen-stable medicament composition as in claim 6, wherein said antibiotic is oxytetracycline.
Claim 9
Dependent Claim
13 words
A rumen-stable medicament composition as in claim 6, wherein said antibiotic is erythromycin.
Claim 10
Dependent Claim
14 words
A rumen-stable medicament composition as in claim 6, wherein said antibiotic is bacitracin zinc.
Claim 11
Dependent Claim
28 words
A rumen-stable nutrient composition as in claim 3, wherein said other nutrient is selected from the group consisting of carbohydrates, proteins, amino acids, vitamins, minerals, and mixtures thereof.
Claim 12
Dependent Claim
15 words
A rumen-stable nutrient composition as in claim 12, wherein said other nutrient is vitamin A.
Claim 13
Dependent Claim
33 words
A rumen-stable composition as in claim 2, wherein said cellulose propionate 3-morpholinobutyrate is present as an external coating over said material and in an amount equal to at least about 0.5 weight percent.
Claim 14
Dependent Claim
64 words
An improved feed composition comprising a blend of (a) common animal food material coated with (b) a solid particulated, rumen-stable composition that is soluble in an aqueous solution having a pH below about 5; said rumen-stable composition comprising: i. a material selected from the group consisting of methionine and mixtures thereof with other medicaments and nutrients, and coated with ii. a cellulose propionate 3-morpholinobutyrate.
Claim 15
Dependent Claim
25 words
An improved feed composition as in claim 15, wherein said material to be protected from direct contact with rumen fluids includes methionine and a medicament.
Claim 16
Dependent Claim
25 words
An improved feed composition as in claim 15 wherein said material to be protected from direct contact with rumen fluids includes methionine and a nutrient.
Claim 17
Dependent Claim
39 words
A coated composition comprising: a. a core material selected from the group consisting of methionine and mixtures thereof with oral ruminant medicaments and nutrients, and coated with b. a coating material; said coating material comprising a cellulose propionate 3-morpholinobutyrate.
Claim 18
Dependent Claim
54 words
A coated composition as in claim 18, wherein said cellulose propionate 3-morpholinobutyrate is stabilized to inhibit spontaneous degradation by the presence in said coating material of an effective amount of an antioxidant, and said nitrogen-containing cellulosic derivative is present in said coated composition in an amount equal to at least about 1 weight percent.
Claim 19
Dependent Claim
25 words
A coated composition as in claim 19, wherein said cellulose propionate 3-morpholinobutyrate has a composition that falls within the area designated A in the drawing.
