The present invention provides a method of use, and a composition, of a carbohydrase and/or a protease for the manufacture of an agent for the treatment and/or prophylaxis of coccidiosis. The agent can be in the form of a cereal-based animal feed. The carbohydrase may be a polysaccharidase such as a xylanase or a cellulase e.g., .beta.-glucanase. The agent may include conventional non-enzymic anticoccidial agents.

Method and composition for treatment and/or prophylaxis of coccidiosis

A method for preventing and treating parasitic infections in animals by administering a lysine analog, such as EACA, to the animals on a continuous basis. In the preferred embodiment, the method of the present invention is directed to preventing and treating coccidial infections in poultry by adding EACA to the daily diet of a poultry flock. EACA may also be administered in ovo before hatching. The administration of EACA enhances the natural immune response of the poultry to the invading coccidial organisms and enables the poultry to combat the parasites without the need for antibiotics. Another aspect of the present invention involves preventing parasitic diseases in humans and animals by prophylactically administering a serine protease inhibitor, such as EACA, as an adjuvant in conjunction with a conventional vaccine effective against the target parasite.

Method for preventing and treating coccidiosis

The present invention relates to the use of a combination of a protease and an inner salt of a quaternary amine carboxylic acid for the preparation of an agent for the treatment and/or prophylaxis of coccidiosis and bacterial infections such as necrotic enterities in animals. Preferred embodiments of the invention comprise the inclusion of a xylanase and/or an .alpha.-amylase in the agent. A nutritional additive comprising a combination of an inner salt of a quaternary amine carboxylic acid protease and (optionally) a xylanase and an .alpha.-amylase is also disclosed. It can be used for improving the rate of weight gain of animals.
