The 2 most common changes livestock and poultry producers are making in response to the loss of shared use antibiotics are increased use of vaccines and better sanitation and biosecurity.
That was a key finding of a new study just completed by Brakke Consulting, Inc. The survey, “New Strategies for Health and Performance in US Livestock and Poultry Production,” was conducted among beef, dairy, swine and poultry producers in late 2016.
New antibiotic regulations and the Veterinary Feed Directive was effective Jan. 1, 2017. Although there was some variation among species groups, vaccination protocols and improved sanitation were the top 2 strategies for 70% or more of all producers. Other strategies included reduced co-mingling of animals/birds, changes in feed additives, changes in facilities, use of immune modulators and changes in genetics.
The most common change in feed additives was increased use of direct-fed microbials, also called probiotics. Other less common feed additive changes included increased use of enzymes, prebiotics, oligosaccharides, organic acids and phytogenics.
More than 90% of poultry producers indicated that they were changing one or more feed additives in response to the loss of antibiotics, more than any other species group. Although the study was conducted late in 2016, only half of producers said they had already made changes to their operations.
About 3/4 indicated that they were ready for the changes, however. The poultry sector was the most prepared. There was widespread concern about the potential impact of the loss of shared use antibiotics. Only 38% of producers believed that they would be able to maintain production and profit levels without them.
