- Enterotoxigenic Escherichia coli strains expressing F4 (F4-ETEC) are a significant cause of post-weaning diarrhea in pigs, and a study evaluated the effectiveness of an oral vaccine, Coliprotec® F4, to protect against this issue.
- The vaccine was administered to pigs one day after weaning, with results showing a notable decrease in diarrhea severity and F4-ETEC colonization and shedding, particularly at 7 and 21 days post-vaccination.
- The protective effects were linked to specific antibodies developed in pigs, indicating that the vaccine works well even in the presence of maternal antibodies and offers protection within just 7 days.
The efficacy of tulathromycin in the treatment (phase 1) and prevention (phase 2) of bovine respiratory disease (BRD) was evaluated on commercial farms in France, Germany, Italy, and Spain. In phase 1, commingled cattle with clinical BRD were treated with tulathromycin (n = 128) or florfenicol (n = 125) on day 0. Similar percentages of animals showed sustained clinical improvement at day 14 (tulathromycin 83.
