    • The present invention relates to a product and process for assuring the transfer of adequate passive immunity to newborn domestic animals. Immunologically active immunoglobulins are extracted from the whey byproduct of dairy manufacturing by using ultrafiltration techniques to separate the large immuoglobulin molecules from the whey. The ultrafiltration retentate is dried to produce a filtered product having a high concentration of immunoglobulins. The dry filtered product is assayed to verify the immunological activity of the product and to measure the distribution and concentration of pathogen specific antibodies. The dry filtered product is stored. Subsequently, a dose of the product containing at least a minimum weight ratio of immunologically active Ig is fed to the newborn animal to transfer passive immunity. Ion exchange techniques can be combined with ultrafiltration techniques to significantly increase the Ig concentration in the ultimate product while simultanously reducing the net cost of producing the product. They whey-derived product may also be used on a continuous basis as a food supplement for an animal to enable the immunologically active immunoglobulin molecules in the product to attack pathogens present in the digestive system of the animal.
    • 本发明涉及一种确保向新生儿家畜转移足够的被动免疫的产品和方法。 通过使用超滤技术从乳制品的乳清副产物中提取免疫活性的免疫球蛋白以从乳清中分离出大的免疫球蛋白分子。 将超滤保留物干燥以产生具有高浓度免疫球蛋白的过滤产物。 测定干燥过滤的产物以验证产物的免疫活性并测量病原体特异性抗体的分布和浓度。 储存干燥过滤的产品。 随后,将含有至少最小重量比的免疫活性Ig的产品的剂量喂给新生动物以转移被动免疫。 离子交换技术可以与超滤技术结合,以显着提高最终产品中的Ig浓度,同时降低生产产品的净成本。 它们的乳清衍生产品也可以连续使用作为动物的食物补充物,以使产品中免疫活性的免疫球蛋白分子能够攻击存在于动物消化系统中的病原体。
