Abstract: A method of suppressing appetite and reducing weight gain in animals and human beings includes the step of administering to the animal a high dose of an antibody to a gut peptide.

Abstract: A method for reducing gastrointestinal inflammation in an animal is disclosed. The method involves administering to the animal an agent that reduces the bioavailability in the animal of a prostaglandin or leukotriene lipid precursor wherein the agent comprises an antibody.

Abstract: A method for enhancing bodily growth or improving feed efficiency in animals reduces the availability of a prostaglandin or leukotriene precursor.

Abstract: An egg enriched for conjugated linoleic acid and having a normal appearance is produced by feeding poultry a diet enriched in conjugated linoleic acid (CLA) and a selected monounsaturated fatty acid. A poultry feed supplemented having conjugated linoleic acid and a selected monounsaturated fatty acid.

Abstract: Disclosed is a method for selectively inhibiting cyclooxygenase-2 in an animal having a cyclooxygenase-2 activity by delivering into the animal an amount of a conjugated linoleic acid effective to reduce cyclooxygenase-2 activity in the animal.

Abstract: A method of treating meat animals to increase fat firmness, shelf life and meat quality indices consisting of administering to the meat animals a safe and effective amount of conjugated linoleic acid or CLA.

Abstract: A method for treating an animal to reduce body fat while the animal exhibits improved feed efficiency and either continued weight gain or an increase in lean body mass includes the steps of administering to the animal a combination of CLA isomers in a ratio selected to retain a desirable benefit attributable to one isomer while counteracting an undesirable effect of the same isomer.

Abstract: A method of increasing food efficiency in both avians and mammals by using antibodies to gut peptides such as choleocystokinin to elicit a biological response which decreases gastrointestinal motility, reduces satiety or improves feed efficiency.

Abstract: A method of improving the efficiency of an animal to convert feed into desirable body tissue involves feeding the animal feed particles having an inner core of nutrients and an outer layer containing a conjugated fatty acid or an antibody that can protect the animal from contacting diseases that can adversely affect the animal's ability to grow or efficiently convert its feed into body tissue.

Abstract: A method of enhancing the activity of natural killer lymphocytes and a method for increasing the basal level of natural killer activity in an animal include the step of administering orally or parenterally to said animal a safe amount of CLA, said amount being effective to enhance the activity of killer lymphocytes or to enhance the basal activity of killer lymphocytes in the animal.

Abstract: Methods and apparatus are disclosed for determining the presence of a catabolic state in an organism (or collection of organisms) by measuring changes in isotopic ratios in biological materials obtained from them. Preferably, .sup.13 C/.sup.12 C ratios are monitored for isotopically unenriched animals, such as by testing changes in the ratio in blood or breath.

Abstract: Methods of inhibiting lipoprotein lipase and controlling the body fat and the body weight of an animal employ an effective amount of at least one 20 carbon, conjugated, unsaturated, fatty acid. Pharmaceutical compositions for use in the method are also disclosed. The 20-carbon conjugated fatty acids are selected from an eicosadienoic acid, an eicosatrienoic acid, and an eicosatetraenoic acid. Preferably, the fatty acids are 11,13-eicosadienoic acid; 12,14-eicosadienoic acid; 8,11,13-eicosatrienoic acid; 5,8,11,13-eicosatetraenoic acid; 5,8,12,14-eicosatetraenoic acid, or an ester, salt, or mixture thereof.

Abstract: A method of treating meat animals to increase fat firmness and meat quality indices which increases meat processability consists of administering to the meat animals a safe and effective amount of conjugated linoleic acid or CLA.

Abstract: Methods of treating animals to maintain or elevate CD-4 and CD-8 cell levels and to prevent or alleviate the adverse effects on the animal caused by the production or exogenous administration of tumor necrosis factor (TNF) or by a virus consist of administering to the animal a safe and effective amount of a conjugated linoleic acid (CLA) or a substance which is converted in the animal into CLA. A method of preparing CLA employing a bacteria isolated from a rat colon also is disclosed.

Abstract: A method of increasing food efficiency in both avians and mammals by using antibodies to gut peptides such as choleocystokinin to elicit a biological response which decreases gastrointestinal motility, reduces satiety or improves feed efficiency.

Abstract: A method of maintaining an existing level of body fat or body weight in a human which comprises administering to a human desiring to maintain that existing level a safe and effective amount of conjugated linoleic acid (CLA) to maintain that level.

Abstract: The novel compound which is the reverse amino acid sequence of a naturally occurring peptide will elicit an immune response when introduced into an organism. Antibodies raised to this reverse compound act as antagonist to the naturally occurring peptide thereby mimicking the natural peptide's physiological effect on the organism's system. Precisely, antibodies specific to reverse choleocystokinin elicit the same response in avians and mammals as naturally occurring choleocystokinin, that being an increase in satiety and a decrease in food consumption.

Abstract: A method of treating an animal to maintain or enhance the mineral content of the bones of the animal consists of administering to the animal a safe and effective amount of CLA. Compositions for use in the method are also disclosed.

Abstract: Methods of treating a bird to prevent skeletal problems consist of administering to the bird a safe and effective amount of CLA (conjugated linoleic acid).
