Abstract
A method for the continuous production of a purified immunoglobulin preparation wherein the antibodies are substantially enriched by means of a selective two-step ammonium sulfate fractionation procedure employing centrifugation and ion depletion processes. The purified immunoglobulins are subsequently commingled with condensed skim milk and spray dried. The resulting product for example is employed in the formulation of milk replacers for artificial rearing of neonatal pigs to provide the passive immunity to disease normally provided by sows' colostrum and later milk.
