Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
48 words
A method for increasing fertility in a food producing animal selected from the bovine, porcine or ovine species, comprising: administering a fertility increasing amount of somatotropin to said animal in the finishing stage of growth thereby increasing embryonic survival and litter size during the reproductive stage of growth.
Claim 2
Independent Claim
48 words
A method for increasing fertility in a food producing animal selected from the bovine, porcine or ovine species, comprising: administering a fertility increasing amount of somatotropin to said animal in the finishing stage of growth thereby increasing embryonic survival and litter size during the reproductive stage of growth.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein said somatotropin is administered in amounts of from about 0.1-20 mg/animal/day.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein said animal is from the porcine species.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein said somatotropin is administered parenterally.
Claim 6
Dependent Claim
31 words
The method of claim 4 wherein said somatotropin is administered using an implant, said implant comprising: a biocompatible and somatotropin compatible implant material; and a fertility increasing amount of said somatotropin.
Claim 7
Dependent Claim
32 words
The method of claim 4 wherein said somatotropin is administered in an injectable formulation, said injectable formulation comprising: a biocompatible and somatotropin compatible carrier; and a fertility increasing amount of said somatotropin.
Claim 8
Dependent Claim
22 words
The method of claim 5 wherein said carrier is a buffer containing about 300 mg/ml arginine hydrochloride and about 0.9% benzyl alcohol.
Claim 9
Dependent Claim
12 words
The method of claim 1 wherein said somatotropin is a recombinant somatotropin.
Claim 10
Dependent Claim
18 words

Claim 12
Independent Claim
39 words
A method for increasing fertility in a swine, comprising: administering a fertility increasing amount of porcine somatotropin to said swine in the finishing stage of growth thereby increasing embryonic survival and litter size during the reproductive stage of growth.
Claim 13
Independent Claim
39 words
A method for increasing fertility in a swine, comprising: administering a fertility increasing amount of porcine somatotropin to said swine in the finishing stage of growth thereby increasing embryonic survival and litter size during the reproductive stage of growth.
Claim 14
Dependent Claim
17 words
The method of claim 11 wherein said somatotropin is administered in amounts of from about 0.1-20 mg/swine/day.
Claim 15
Dependent Claim
11 words

Claim 16
Dependent Claim
31 words
The method of claim 13 wherein said somatotropin is administered using an implant, said implant comprising: a biocompatible and somatotropin compatible implant material; and a fertility increasing amount of said somatotropin.
Claim 17
Dependent Claim
32 words
The method of claim 13 wherein said somatotropin is administered in an injectable formulation, said injectable formulation comprising: a biocompatible and somatotropin compatible carrier; and a fertility increasing amount of said somatotropin.
Claim 18
Dependent Claim
22 words
The method of claim 15 wherein said carrier is a buffer containing about 300 mg/ml arginine hydrochloride and about 0.9% benzyl alcohol.
Claim 19
Dependent Claim
12 words
The method of claim 11 wherein said somatotropin is a recombinant somatotropin.
Claim 20
Dependent Claim
13 words

Claim 21
Dependent Claim
17 words

Claim 22
Independent Claim
41 words

Claim 23
Independent Claim
41 words
