| PATENT CLAIMS |
We claim: 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 |
| PATENT DESCRIPTION |
FIELD OF THE INVENTION The present invention generally relates to animal nutrition. More particularly, it relates to a method of increasing the efficiency of feed conversion in an animal into body weight. BACKGROUND OF THE INVENTION The efficiency of feed conversion into body weight varies significantly among different species of animals. Because feed is a relatively expensive cost factor in the production of food producing animals (50 to 70% of the cost of production), any improvement in the ability of the animal to convert feed into food products can directly improve the profitability of a food producer. For example, an increase in the efficiency of feed conversion in broilers that results in a 1% increase in body weight for the same amount of feed could alone result in savings of over 85 million dollars for the U.S. broiler industry. In addition, there would be millions of dollars of savings because of reduced mortality and a reduction in the days required before marketing the broilers. There is a need for a method of improving the ability of healthy meat animals to more efficiently convert their feed to body weight or other edible products. There also is a need for a safe and effective method for increasing the body weight of animals, including humans, who for medical or other reasons can only consume a limited amount of food. BRIEF SUMMARY OF THE INVENTION It is an object of the present invention to disclose a method of enhancing weight gain and feed efficiency in an animal. We have discovered a method of enhancing weight gain and feed efficiency in an animal which comprises administering to said animal a weight gain enhancing and feed efficiency enhancing amount of a conjugated linoleic acid (CLA) selected from 9,11-octadecadienoic acid; 10,12-octadecadienoic acid; and mixtures thereof. It will be apparent to those skilled in the art that the forementioned objects and other advantages may be achieved by the practice of the present invention. DESCRIPTION OF THE PREFERRED EMBODIMENT In a preferred embodiment of the method of the present invention the safe and effective amount of the conjugated linoleic acid, which is selected from 9,11-octadecadienoic acid; 10,12-octadecadienoic acid and mixtures thereof, is added to the feed of an animal in which it is desired to enhance the efficiency of feed conversion and enhance body weight. The amount of the conjugated linoleic acid to be added to the animal's feed will vary with the species and size of the animal. However, since the conjugated linoleic acids are natural food ingredients and relatively non-toxic, the amount which can be administered is not critical as long as it is enough to be effective. |
