Evaluation of the clinical efficacy of a water soluble formulation of tylvalosin in the control of enzootic pneumonia associated with Mycoplasma hyopneumoniae and Pasteurella multocida in pigs.

Background: The efficacy of a water soluble formulation of tylvalosin (Aivlosin® 625 mg/g granules) was evaluated in the treatment and metaphylaxis of Enzootic Pneumonia (EP) in pigs. In all four trials, pigs in the tylvalosin group were administered 10 mg tylvalosin/kg bodyweight in drinking water daily for 5 consecutive days (TVN). In a single-challenge study, pigs were inoculated with lung homogenate containing Mycoplasma hyopneumoniae.

Treatment of experimentally induced bovine respiratory disease in young calves with a single administration of a combination of florfenicol and meloxicam.

This study was designed to evaluate the efficacy of a new florfenicol/meloxicam combination (FMC) in calves with bovine respiratory disease. A total of 90 young calves were challenged via intratracheal deposition of 10 colony-forming units of Data for 84 calves demonstrating a rectal temperature (RT) above 39.5°C and a combined total clinical score (TCS) greater than or equal to 3 were included.
