Abstract
Abstract A method of improving the metabolic stability of neonatal pigs and increasing their survival rate by administering to the pregnant sow during its latter stages of gestation up to about 80 days prior to parturition an effective amount of a material selected from the group consisting of a dihydroxy alkanol having 3 to 10 carbon atoms; a triglyceride of glycerol and fatty acids wherein at least one of the fatty acid moieties containing 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; the mono and diol esters of said alkanols and said fatty acids wherein at least one of the fatty acid moieties contains 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; and the ester of said dihydroxy alkanol and fatty acids containing 13 to 20 carbon atoms.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A method of improving the metabolic stability of neonatal pigs and increasing their survival rate which comprises administering to a pregnant sow during its latter stages of gestation, up to about 80 days prior to parturition, an effective amount of a material selected from the group consisting of (1) a dihydroxy alkanol having 3 to 10 carbon atoms; (2) a triglyceride of glycerol and fatty acids wherein at least one of the fatty acid moieties contains 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; (3) the mono and diol esters of said dihydroxy and said fatty acids wherein at least one of the fatty acid moieties contains 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; and (4) the ester of said dihydroxy alkanol and said fatty acids containing 13 to 20 carbon atoms.
Claim 2
Independent Claim
149 words
A method of improving the metabolic stability of neonatal pigs and increasing their survival rate which comprises administering to a pregnant sow during its latter stages of gestation, up to about 80 days prior to parturition, an effective amount of a material selected from the group consisting of (1) a dihydroxy alkanol having 3 to 10 carbon atoms; (2) a triglyceride of glycerol and fatty acids wherein at least one of the fatty acid moieties contains 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; (3) the mono and diol esters of said dihydroxy and said fatty acids wherein at least one of the fatty acid moieties contains 8 to 12 carbon atoms with the remaining acid moieties containing 13 to 20 carbon atoms; and (4) the ester of said dihydroxy alkanol and said fatty acids containing 13 to 20 carbon atoms.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein the dihydroxy alkanol is 1,3-Butanediol.
Claim 4
Dependent Claim
32 words
The method of claim 1 wherein the alkanol, the triglyceride or the mono and diol ester of said alkanols and fatty acids are added as a food supplement to the sow's diet.
Claim 5
Dependent Claim
42 words
The method of claim 3 wherein the alkanol, the triglyceride or the mono and diol ester of said alkanols and fatty acids are added in an amount sufficient to provide about 2 to 20% of the dietary energy in the sow's diet.
Claim 6
Dependent Claim
35 words
The method of claim 1 wherein the alkanol, the triglyceride and the mono and diol esters of said alkanols and fatty acids are administered about 12 to 40 days before parturition and continued until parturition.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein the monoester is 1,3-Butanediol monooctanoate.
Claim 8
Dependent Claim
42 words
The method of claim 1 wherein the alkanol, the triglyceride or the mono and diol ester of said alkanols and fatty acids are added in an amount sufficient to provide about 4 to 8% by the dietary energy in the sow's diet.
Claim 9
Dependent Claim
21 words
The method of claim 1 wherein the OH groups of the dihydroxy alkanol are on the first and third carbon atoms.
