To increase, in the milk of bovids, the quantity of antibody specific screw - to - screw of an antigen, the products obtained by this process and their application in veterinary medicine

摘要

An enhanced yield of antibodies specific to an antigen, which neither propagates in the mammary gland of a lactating bovine nor produces in the milk of a bovine any significant quantity of antibodies specific to the antigen, is obtained in the milk of a lactating bovine by inoculating the antigen into the mammary gland of a lactating bovine on at least two consecutive days at intervals during the lactation period of the bovine; the bovine having first been inoculated with the antigen either during its dry prepartum period or during the 24 hour period after parturition. By using such a process a bovine milk product can be produced containing anti-transmissible gastroenteritis antibodies that can be used to protect baby pigs against transmissible gastroenteritis.
