Abstract

A method of enhancing weight gain and feed efficiency in an animal which comprises administering to the animal a safe and effective amount of a conjugated linoleic acid.

Claims

1. A method of increasing the efficiency of feed conversion to body weight in an animal which comprises administering orally or parenterally to said animal a safe amount of a member selected from the group consisting of 9,11 octadecadienoic acid, 10,12-octadecadienoic acid and non-toxic salts thereof which is effective to increase the efficiency of feed conversion to body weight in the animal.

2. A method of claim 1 in which the animal is a bird.

3. A method of claim 1 in which the animal is a mammal.

4. A method of modifying an animal food to increase the ability of the animal food to increase the efficiency of the conversion of the food to body weight in an animal, said method comprising adding to said animal food a safe amount of a conjugated linoleic acid selected from the group consisting of 9,11-octadecadienoic acid, 10,12-octadecadienoic acid, and mixtures thereof, said amount being effective to increase the efficiency of food conversion in the animal.
