Summary
We have previously demonstrated that lung lesions decrease average daily gain in lambs. We have also observed fall born lambs have a lower prevalence of lung lesions than spring born lambs. The different prevalence in lung lesions between spring and fall born lambs suggests that lung lesions can be prevented. Mannheimia (Pasteurella) haemolytica and/or Pasteurella multocida are present in lambs with moderate or severe lung lesions, but not in lambs with normal lung tissue. In serial slaughter studies, we observed lung lesions formed post-weaning. Therefore, we designed two studies to test possible intervention strategies to reduce the prevalence or severity of lung lesions. In the first study, lambs were vaccinated against Mannheimia (Pasteurella) Haemolytica and Pasteurella Multocida at 4 and 2 weeks prior to weaning, at weaning, and 2 and 6 weeks after weaning (a minimum of 21 days before slaughter).
