Bovilis Cavalry 9 from Merck Animal Health is a
convenient, low-dose clostridial vaccine that offers protection against nine
clostridial diseases including red water and tetanus.. It is recommended for the active immunization of healthy
cattle 3 months of age or older as an aid in the prevention of disease caused
by Clostridium tetani, C. chauvoei, C.
septicum, C. novyi Type
B, C. haemolyticum, C. sordellii, and C.
perfringens Types C
& D.
Immunity is also provided as an
aid in the prevention of diseases caused by the beta and epsilon toxins of an
additional organism, C. perfringens Type B. Although C. perfringens Type B is not a significant problem in
North America (US), immunity is derived from a combination of Type C (beta) and
Type D (epsilon) C. perfringens fractions.
Administration & Dosage
Shake well. Inject 2 mL subcutaneously followed by a 2 mL dose in 3 weeks. Calves vaccinated at 3-6 months of age should be given a 3rd vaccination with either this vaccine, or another vaccine containing C. perfringens Type D epsilon toxoid, to aid in the prevention of disease caused by C. perfringens Type D. Revaccinate annually with 2 mL prior to periods of extreme risk or parturition.
