         Vaccines, while important,
      are only as good as the man-
      agement system they are
      provided under.  The goal of
      any vaccine is not to prevent
      infection, but rather to form
      a robust immune response
      against  specific  organisms,
      should the animal become ex-
      posed. Depending on the type
      of vaccine, the immune system
      will respond in different ways.
      Vaccines work more efficiently
      when given at the appropriate
      time according to manufactur-
      er or veterinarian recommen-
      dations. When calves are born
      later in the calving season, this
      becomes detrimental to their
      vaccine schedule, as well as
      the cows due to varying levels
      of immunity and responsive-
      ness to vaccines. Pre-breed-

      ing vaccines should take place                           MAKE SURE YOU ARE

      Calf Growth
         A final thought to consid-
      er is the overall potential for
      growth of the calves being pro-
      duced.  We  know  that  calves                 PHONE: 417-644-2993 - EMAIL:  CATTLEMAN@CUTTINGEDGEUS.COM
