come to mind, and if the name
appears exotic, such compounds
(thousands) exist in nature in abundance: rosemary, cinnamon, olive
leaves, grape seeds, clove, wood
flavonoids and many others that
we call phytogenics or botanicals. As it happens, many diets
already include such compounds
because some possess antibacterial
properties and they contribute in
antibiotic-free nutrition programs.
Here, it should be stressed out that
not all such products are created
equally with many ineffective/
cheap products flooding the market.
The third question that needs
an answer is the substitution rate.
This is something that you
must discuss with
because it affects
the financial outcome of the whole
exercise. If you already use phytogenics, you must calculate what
part of such product(s) also offers
antioxidant properties. If it is a new
product, the final result must be
less expensive than "doing nothing"
as discussed above. Animal trials
help, and for that I only need to add
that although "rat" trials are important as a first step, I always prefer to
see trials with the same animal as
that which will consume the product/feed in question. ■
