Tóm tắt

The results showed that the vaccine provoked neither fever (p ≥ 0.05), nor local reaction although two piglets did vomit 30 min. after vaccination. Significant differences were found when evaluating the productive parameters between groups. Group 0ne presented a significant reduction (p < 0.00001) of the pulmonary lesions attributed to M. hyopneumoniae compared with Group Two.
