Giving your pigs a strong start

Kavault is a first-in-class antimicrobial proven to reduce the incidence and overall severity of diarrhea in the presence of pathogenic Escherichia coli in groups of weaned pigs, during the phase when pigs are most at risk.

 E.coli prevalence and impact

Pathogenic E. coli is costly and prevalent in the swine industry. One of the most important causes of post-weaning diarrhea (PWD) in pigs, it ranks among the most common diseases overall in global swine production.1 A major source of frustration and worry, E. coli costs producers in prevention, diagnosis, treatment, mortality and reduced performance. 

 Post-weaning diarrhea

At the post-weaning stage, pigs are at risk of E. coli exposure from common conditions like transport, relocation, commingling, loss of maternal antibodies and change to a solid diet. Clinical signs of E. coli typically appear 5-15 days after weaning and can last for 21 days or more. During this time, the disease can significantly affect herd health and performance.2

 Avilamycin overview

Avilamycin, the active ingredient in Kavault, is a first-in-class orthosomycin antibiotic. Developed exclusively as an animal-use antibiotic, it has never been used in humans. Avilamycin's animal-use only profile aligns with responsible antibiotic use. Avilamycin also has established maximum residue limits with CODEX and the EU, and is only available with a veterinary feed directive (VFD).

Kavault use and safety information

The label contains complete use and safety information, including cautions and warnings. Always read, understand and follow the label and use directions. 

Directions for use

Feed at 73 grams avilamycin per ton of Type C medicated feed (80 ppm) as the sole ration for 21 consecutive days. The veterinarian may direct feeding for up to a total of 42 consecutive days, based on clinical assessment. Feed to pigs that are at risk of developing, but net yet showing sins of diarrhea in the presence of pathogenic Escherichia coli.

Important safety information

  • Caution: Federal law restricts medicated feed containing this veterinary feed directive drug to use by or on the order of a licensed veterinarian. 
  • No withdrawal period required when fed according to the label.
  • To assure responsible antimicrobial drug use in pigs, do not administer to pigs 14 weeks of age or older or for more than  a lifetime total of 42 days.
  • VFD expiration date must not exceed 90 days from the date of issuance. VFDs for avilamycin shall not be refilled.
  • Avilamycin has not been demonstrated to be effective in pigs showing clinical signs of diarrhea prior to the start of medication.
  • Avoid inhalation, oral exposure, and direct contact with skin or eyes.
