Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
47 words
A method of increasing the quantity of mammary parenchyma in a ruminant which comprises administering a mammary parenchyma growth stimulating amount of a ruminant growth hormone to said ruminant between about the onset of puberty and about the first parturition, thereby increasing milk production during subsequent lactations.
Claim 2
Independent Claim
47 words
A method of increasing the quantity of mammary parenchyma in a ruminant which comprises administering a mammary parenchyma growth stimulating amount of a ruminant growth hormone to said ruminant between about the onset of puberty and about the first parturition, thereby increasing milk production during subsequent lactations.
Claim 3
Dependent Claim
21 words
A method as in claim 1 where the growth hormone is administered between about the onset of puberty and first conception.
Claim 4
Dependent Claim
11 words
The method of claim 1 where the ruminant is a cow.
Claim 5
Dependent Claim
21 words
The method of claim 1 where the growth hormone is exogenous hormone equivalent to the hormone naturally produced by the ruminant.
Claim 6
Dependent Claim
14 words
The method of claim 4 where the growth hormone is isolated from pituitary gland.
Claim 7
Dependent Claim
21 words
The method of claim 4 where the rumnant is a cow and the growth hormone is recombinantly derived bovine growth hormone.
