Abstract: An improved method and apparatus is disclosed for adding fluids to, or removing fluids from, a body part or organ of an animal which minimizes animal trauma and permits rapid, easy, repeated fluid or low viscosity gel transfers. The apparatus includes a tubular fluid-conveying element adapted for fixed connection to the animal, along with a flexible fluid conduit connected between the element and a specific internal body part or organ, such as a cow's uterus. In use, a syringe is employed to introduce or remove fluids from the body part, through the tubular element and connected conduit. The invention is especially adapted for introducing and recovering cell lines producing monoclonal antibodies or other biologically active products in large mammals, and fascilitates monitoring of antibody production as well as administration of nutrients to enhance cell line growth.
