Abstract: Please insert the attached Abstract provided herewith on a separate sheet after the claims. The present invention pertains to a method for administering a predetermined amount of a pharmaceutical composition to an animal comprising the steps of taking a cannula suitable for insertion into a nasal cavity of the animal, slidably connecting the cannula to a delivery device which is suitable for holding the pharmaceutical composition, inserting the cannula via a nostril into the nasal cavity such that a peripheral line of the cannula is contiguous with a circumferential line of the nostril, actuating the delivery device to force the said amount of the pharmaceutical composition through the cannula into the nasal cavity, retracting the cannula from the nasal cavity and removing the cannula from the device. The invention also pertains to an apparatus for performing this method, a cannula for use with the apparatus and a kit containing the required components to perform the method.

Abstract: An improved weight and growth stimulant for domesticated animals such as cattle, pigs and sheep is comprised of an anabolic agent that is subcutaneously administered in the form of a dual release implant formulation. Increased gains are particularly improved when zeranol is administered in an immediate-release and controlled-release formulation which allows for a one-time dosage injection.
