      K-State experts discuss health considerations for herds calving in spring and fall

         While many beef produc- herds that calve in the fall  cattle  as two
      ers only calve once per year,  and spring, that is twice per  subgroups
      there are some who maintain  year,” he said.                          of the  same

      bulls, said veterinarians with
      the Beef Cattle Institute at
      Kansas State University.
         “In large operations that
      follow both a spring and fall
      calving season, the cost per
      pregnancy is reduced if they
      use the same set of bulls for
      both breeding seasons,” said
      K-State veterinarian Bob
      Larson on a recent  Cattle
      Chat podcast.
         Between breeding seasons
      is the right time to make
      sure the bulls are ready to go
      again, said the veterinarians.
         “After coming off a breed-
      ing season, he’s probably lost
      body condition,” Larson said.
         BCI director and veteri-
      narian Brad  White added:
      “The more time you have be-
      tween the breeding seasons,
      the easier it is to change the
      body condition of the bulls.”
         Nutritionally       speaking,
      BCI  beef  cattle  nutritionist
      Phillip Lancaster said it is
      important for producers to
      be aware of their grasses for
      those bulls that are being
      maintained on pastures.
         For bulls out on cool season
      grasses, those are starting to
      grow  again and can provide
      good nutrition said Lancast-
      er, but for bulls grazing on
      warm season grasses, sup-
      plementation may be needed.
         “This  time  of year,  pro-
      ducers may need to offer the
      bulls a protein supplement
      and possibly some additional
      hay depending on how much
      forage is still in the pasture,”
      Lancaster said.
         Along with body condition,
      bulls  also need  a thorough
      conformation       examination
      and semen quality test as
      part of a routine breeding
      soundness exam, according
      to Larson.
         “The breeding soundness
      exam needs to be done once
      per breeding season. So, for
