USDA approves Elanco's AviPro® Megan® Egg for turkeys
Elanco Animal Health has announced the USDA's approval of AviPro® Megan® Egg for Salmonella prevention in live turkey production.
AviPro Megan Egg for turkeys is a vaccine recommended as an aid in immunity development and the prevention of Salmonella Typhimurium (ST) colonisation of the liver and spleen.
Prior to the expanded label indications for turkeys, AviPro Megan Egg was approved for the vaccination of chickens to help mitigate the disease's colonisation of the internal organs, intestinal tract, and ceca.
As part of a comprehensive Salmonella control programme, AviPro Megan Egg - for less than two cents per bird - is safe and effective, and the first Salmonella vaccine to be labeled for turkeys. With coarse spray and drinking water applications, its two-dose application protocol easily adapts to most vaccine programmes.
"Prioritising food chain, brand and bird protection with consistent, comprehensive Salmonella control programmes mitigates risk from egg to end consumer," said Dr. Brian McComb, poultry technical consultant at Elanco. "The expansion of AviPro Megan Egg in turkeys supports a proactive approach to Salmonella control, enabling companies to reduce Salmonella risk while meeting customer, regulatory, and ultimately consumer demands."
In a controlled study, one-day old birds were vaccinated with AviPro Megan Egg, revaccinated through drinking water at three weeks of age and then challenged with wild Salmonella Typhimurium at seven weeks of age. Megan Egg-treated birds showed significantly reduced Salmonella colonisation post-challenge compared to non-vaccinated birds.
Vaccination has proven to be a valuable tool in a comprehensive Salmonella control programme. However, vaccination alone can't be relied upon to prevent Salmonella, Elanco said. A comprehensive programme requires an integrated approach, including optimising gut health, strong biosecurity measures, environmental monitoring, litter management, pest and rodent control, and water and feed management.
