proved intestinal health on the other. When you are able
to improve intestinal health, less nutrients are directed
toward an immune response and it is able to utilize those
nutrients more efficiently." 

Keep an open mind, but proceed with caution
In DeRouchey's opinion, phytogenics should and will
be looked at more closely moving forward, but they will
require more independent commercial research to support
their claims to build confidence with U.S. producers. He
also suggests company's identify the cost-benefit before
introducing any new additives.
"Just don't overreact by losing growth promotion levels and feel like you have to do something else," he says.
"There are a lot of producers that don't do anything. We
can survive without [AGPs] but we're going to have to
focus on daily management and on the farm sanitation,
biosecurity. ... We can do a lot more with those areas to
improve our production system than trying to find a magic
bullet to put in the feed. If we're relying on that, our industry is in trouble."
While not referring specifically to phytogenic feed additives, AFIA's senior vice president of legislative and regulatory affairs Richard Seller urges the U.S. feed industry to
be cautious with any product that claims to be an alternative
to antibiotics or one making growth promotion claims.
"Being a veterinarian and nutritionist myself, it's
important to be skeptical, but most of the criticisms
are assumptions that [phytogenics] will not work," says
BIOMIN's Murugesan. "While I agree nothing will even
remotely come close to [AGPs], we have to deal with the
fact that they will not be available and [producers] should
explore the other available options. With phytogenics, the
mode of action is not that simple and very much depends
on formulation as well as application. If you are looking
for a straight forward answer, then yes, it's not going to be
satisfying. It's a comfort zone [some] don't want to leave."
In the end, phytogenics show much potential, but
prospective customers should educate themselves before
adjusting their formulations. ■
