An antimicrobial weapon against respiratory illness in feedlot cattle can now also be used against pneumonias in hogs and non-lactating dairy cattle.

Bayer HealthCare’s Canadian animal health division announced Oct. 24 it has approvals to sell its injectable enrofloxacin solution, Baytril 100, to treat swine respiratory disease (SRD) in hogs, and to treat bovine respiratory disease (BRD) in non-lactating dairy cattle under 20 months of age.

“Left untreated, respiratory disease in pigs causes lung damage and increases mortality, impacting the bottom line,” Dr. Bruce Kilmer, director of technical services and regulatory affairs for Bayer HealthCare’s animal health arm, said in a release.

The product has been available to veterinarians since 2004 to treat recurring respiratory disease in “high-risk” feedlot cattle, the company said.

In hogs, Bayer said, Baytril’s bactericidal effects work against Actinobacillus pleuropneumoniae, Pasteurella multocida and Haemophilus parasuis, the “major culprits” in swine SRD.

In young cattle, Bayer added, Baytril 100 kills Pasteurella multocida and Mannheimia haemolytica, the chief causes of BRD.

The product is “concentration dependent, not time dependent,” and can deliver therapeutic drug concentrations to lung tissues within two hours of a subcutaneous (sub-Q) dose in young cattle as well as hogs, the company said.
