Title: Method and apparatus for inducing immunological and resistant response in mammary glands
IPC: A61D7/00
Filed: 1979-05-04
Abstract: Process and apparatus (see figure 2) are provided for stimulating immune resistance by the introduction of at least one relatively small solid non-toxic substantially non-biodegradable body (22), having nonspecific antigenic action, into each gland cistern of the udder. The body is sufficiently flexible or elastic and of a shape so as to be capable of being shaped into a form small enough to be inserted into the gland cistern through the lactiferous duct and then reformed to its original shape which inhibits its passage from the gland cistern into the teat cistern. The continued presence of the non-specific antigenic body induces immune resistance including an increase in the number and activity of phagocytic cells, particularly leukocyte cells, in the udder.The continued presence of these increased numbers of activated phagocytic cells provides protection against bacterial invasion through the streak canal without degrading milk quality
