ENDOVAC-Dairy® is an Re-17 mutant Salmonella typhimurium bacterin-toxoid. This vaccine utilizes an antigen which is devoid of the outer O-side chains resulting in an exposed cell wall. Since the cell walls of gram negative bacteria are virtually analogous, this “core antigen” vaccine provides cross-protection from many gram-negative endotoxemic diseases.
Independent research has clearly shown the association of endotoxins and the clinical signs of E. coli mastitis. Core-antigen vaccines focus on endotoxins by providing anti-LPS antibodies in response to active immunization. In the largest and most comprehensive efficacy study performed in 1292 dairy cattle, ENDOVAC-Dairy® significantly reduced both the incidence and severity of E. coli mastitis due to E. coli, “The first USDA licensed product with this approval”.
It is recommended that ENDOVAC-Dairy® be used in the dry period to most effectively immunize cattle prior to the time of the highest incidence of E. coli mastitis during early lactation. However, the vaccine is safe in all trimesters.
Inject 2ml into the musculature of healthy cattle. Repeat in 2 or 3 weeks. Administer a 2ml booster dose annually. Not recommended for administration to mastitic cows or to septicemic cattle.
