    • PURPOSE: To establish a high resistant value and lymphokinen level by inoculating an amount of antibody material smaller than that used in a conventional immunizing method by introducing the antibody material into a molding structure of a bio-compatible matrix and transplanting the structure into a mammal. CONSTITUTION: An antibody is introduced into a solid molding product of a matrix comprising a bio-compatible, biodegradable or bio-erosive polymer material, e.g. polylactic acid, polyglycolic acid, poly(lactic acid-co-glycolic acid), polycaprolactone, poly(oxalic acid), polydioxanone, polyorthoester, or a salt thereof, and transplanted into a mammal by an intramuscular injection or a hypodermic injection in the method for immunizing a mammal. The antibody is gradually released from the matrix material for a long period in a regulated rate. This method is effectively used by applying the one to an animal belonging to bovine group to produce an antibody and a lymphokinen factor in the milk.
