Elanco develops new avilamycin antibiotic for swine

Developed for animal use only, Kavault is first-in-class antibiotic that provides new E. coli solution for nursery pigs.

Elanco has announced the availability of Kavault (avilamycin), a new swine product that represents a first-in-class, animal use-only antibiotic for reduction in incidence and overall severity of diarrhea in the presence of pathogenic Escherichia coli in groups of weaned pigs.

Avilamycin is an orthosomycin antibiotic, which is a new class of antibiotics in the U.S. market for animal use only (not medically important). Administered under a veterinary feed directive, the product can be provided to pigs up to 14 weeks of age.

Fed continuously for 21-42 days based on clinical assessment, Kavault is administered to pigs at risk of developing, but not yet showing clinical signs of, diarrhea. Avilamycin features a zero-day withdrawal period.

A 2011 efficacy trial compared diarrhea incidence rates among newly weaned pigs that received avilamycin (73 g per ton) and a non-medicated control group. The trial found a 31.2% reduction in diarrhea incidence rate in pigs that received avilamycin compared to the non-medicated control group.

As one of the most important causes of postweaning diarrhea in pigs, E. coli can significantly impact herd health and performance.

E. coli presents a serious threat to nursery pigs when they are most vulnerable and can cause significant performance loss and even death,” said Dr. Thomas Marsteller, director of swine technical consulting for Elanco. “We’re pleased to offer producers this one-of-a-kind solution for E. coli.”
