Vaccinate for the clostridial complex. The Clostridial complex is a genus of bacteria responsible for several diseases including but not limited to Blackleg,E nterotoxemia, Malignant edema, Red Water and others. These spore-forming bacteria can reside in the soil for long periods of time and are widespread. Sometime during their life, every calf will be challenged by the Clostridial complex.
An annual “Blackleg’ booster administered to the cow herd within 45 days of calving will boost the clostridial antibodies included in colostrums and bolster protection of young calves given to young (2 months of age or less) calves.
However, vaccination of young calves ‘primes’ the immune system and facilitates an effective immune response when the second vaccination is received in colostrums and bolster protection of young calves. Those same maternal given to young (2 months of age or less) calves. However, vaccination of young calves ‘primes’ the immune system and facilitates an effective immune response when the second vaccination is received.
Beef Quality Assurance best management practices require that all injections be given in the neck. If afforded a choice, choose a subcutaneous (under the skin) route of administration over intramuscular. Beef producers should consult with their veterinarian in the design and implementation of a preventative herd health program that may include the use of additional vaccines.
