Abstract
Abstract A method of promoting growth and enhancing feed efficiency in meat producing animals. The 6' esters of zearalanol are effective growth promoting agents in meat producing animals, particularly ruminants, when implanted subcutaneously in said animals to obtain a controlled release of the compositions. Included in this group of compositions are: zearalanol 6'-butyrate; zearalanol 6'-decanoate; zearalanol 6'-hexanoate; zearalanol 6'-laurate; zearalanol 6'-trichloroacetate; and zearalanol 6'-trifluoroacetate.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
73 words
A method of promoting growth in a food-producing animal, the steps comprising administering to said animal a growth promoting amount of a compound represented by the following structural formula ##STR10## in which R is hydrogen; and wherein R 1 is --C 5 H 11 , --C 9 H 19 , --C 3 H 7 , and C 11 H 23 , trifluoromethyl, trichloromethyl, tribromomethyl, nitrophenyl, aminophenyl or a group of the formula ##STR11##
Claim 2
Independent Claim
73 words
A method of promoting growth in a food-producing animal, the steps comprising administering to said animal a growth promoting amount of a compound represented by the following structural formula ##STR10## in which R is hydrogen; and wherein R 1 is --C 5 H 11 , --C 9 H 19 , --C 3 H 7 , and C 11 H 23 , trifluoromethyl, trichloromethyl, tribromomethyl, nitrophenyl, aminophenyl or a group of the formula ##STR11##
Claim 3
Dependent Claim
31 words
The method of claim 1, in which R 1 is --C 5 H 11 ; --C 9 H 19 ; --C 3 H 7 ; or --C 11 H 23 .
Claim 4
Dependent Claim
25 words
The method of claim 2, in which the compound is administered to the animal by controlled release into the animal over a period of time.
Claim 5
Dependent Claim
15 words
The method of claim 3, in which the compound is administered subcutaneously to said animal.
Claim 6
Dependent Claim
30 words
The method of claim 1, in which the compound is in the form of a solid pellet in combination with excipients and diluents, and is subcutaneously implanted in the animal.
Claim 7
Dependent Claim
12 words

Claim 10
Independent Claim
41 words
A method of promoting growth in a ruminant comprising subcutaneously implanting said ruminant with a growth promoting amount of an anabolic agent selected from the group consisting of: zearalanol 6'-butyrate; zearalanol 6'-hexanoate; zearalanol 6'-decanoate; zearalanol 6'-laurate; zearalanol 6'-trichloroacetate; and zearalanol 6'-trifluoroacetate.
Claim 11
Independent Claim
41 words
