HORMONES
IN BEEF
WHAT IS MAVERICK
RANCH’S POSITION ON BOVINE GROWTH HORMONE IMPLANTS IN CATTLE?
First, you need to know that 14 drug companies produce FDA
approved implants. These are all estrogenic or androgenic
compounds. In general, these are small pellets, slightly larger
than a pin head, and are implanted in the middle back of the
animal’s ear. These implants are gradually released over a
60 to 200 day period and in effect, stimulate the animal’s
metabolism.
All scientific
studies prove there is zero risk to humans, and laboratory
tests consistently support this finding. Although safe to
humans, Maverick Ranch’s policy is that we are opposed to
some of the implants and provide an economic incentive to
discourage use. In 1995, several strong androgen implants
became popular. If used, they tend to make steers a little
more like bulls, and some of the beef becomes too lean to
qualify for USDA Select or Choice grade which are the USDA
grades that Maverick Ranch uses. Colorado State University
has recently completed a study that shows that several implant
strategies not only reduce USDA grade, but they make the beef
so lean that it decreases tenderness and palatability.
Since it is important
for a branded beef program to have the best possible eating
qualities, we respond by simply not buying cattle that have
been managed in a way that creates poor eating quality. Genetic
improvement throught genetic breeding for leanness in cattle
has been so great that implants have lost their economic
edge by creating more cattle that “won’t grade” USDA Choice
and Select.
Our Maverick Ranch
system is blessed with the fact that we have an abundance
of producers, so we can buy based on rigid requirements,
which continue to get more stringent in order to ensure that
our beef remains tasty and tender.
Since we permit
certain natural implants and analyze each management system
individually, we are often asked “Why do you still test
for hormones in the laboratory?”
We test because
we realize that each animal responds differently and we want
to make sure that there are no unintentional human mistakes
which would result in a detectable residue. Producers must
follow FDA rules and Maverick Ranch’s rules as well. We feel
that if any man-made steroid can be detected, we can’t represent
the beef as natural. Also, all natural levels have
to be within a safe range; it doesn’t appear that the animals
own endocrine system was functioning abnormally. (Exceeds
levels taken from the Code of Federal Regulations 21 CFR Sec.
556.240) Therefore,
if we detect an antibiotic, man-made steroid, any unusual
bovine growth hormone, or any chemical in our test for over 50 substances,
THOSE CATTLE ARE REJECTED.
There is no way
we can test for every possible chemical influence, as there
are over 80,000 chemicals used in the world today. However,
we can and do test for the substances that we believe are
likely to occur. Sometimes, over 30% of the cattle are rejected.
When that happens, we have to eliminate some producer’s cattle
and allow new producers to enter the program. Our producer
requirements and restrictions are listed in the section for
producers.
