Summary
Two trials were conducted to evaluate the effect of deworming beef cows on weaning weight production and calf sickness. In Trial 1, deworming first-calf heifers with Valbazen approximately 2 weeks prior to the start of calving did not significantly affect calf weaning weight, weight per day of age or number of treatments for sickness. In Trial 2, deworming cows 3 years of age or older with Valbazen or Levasole approximately 2 weeks prior to the start of calving did not significantly affect calf weaning weight, weight per day of age or number of treatments for sickness. Under the experimental conditions of these trials in which control and dewormed cows were managed together and under an apparently low parasite load, deworming did not significantly increase weaning weights. More field research is necessary before we can accurately evaluate the economics of deworming as a management practice in the Northern Great Plains.
