Minerals were created in 1925 and named GROSTRONG in
1926.* With the exception of a few recent changes, such as the
addition of natural-source vitamin E and apple flavoring, they
have remained basically unchanged for over 80 years. The formulas
were ahead of their time, due to the inclusion of salt for
palatability, increased zinc, no added potassium and substantial
amounts of vitamins and trace minerals. They were first available
in granular form.
Later, pasture blocks and the unique patented QuadBLOCK®,
that divides into four-sections for stall feeding, was developed.
With GROSTRONG Minerals products, we have this unprecedented
tradition of excellence plus the latest innovations in
ago MoorMan's and several other feed companies were purchased by
Archer Daniels Midland Company (ADM). The new feed division of
ADM was named ADM Animal Nutrition.
The history of Moorman Manufacturing Company (known as MoorMan's) is best described in this article from the former
MoorMan's Web site:
"At MoorMan's we believe the grain and forage grown by American
farmers and ranchers is the finest livestock and poultry feed
produced in the world.
But in these wonderful feeds there is more meat, milk and eggs
than livestock and poultry can extract without special nutritional
The MoorMan way of serving farmers, ranchers and livestock feeders
is to supply research-proved products made with carefully selected
and processed ingredients. We can help stockmen fit these products
into carefully planned programs which will best fulfill individual
feeding goals. We further provide the services of a conscientious
and well-informed counselor for on-the-spot guidance to help
ensure the most profitable use of products and programs.
It has always been the basic MoorMan philosophy to supply our
customers with products and services for greatest economy of
production and maximum profits. This is MoorMan's contribution to
America's producers of meat, milk and eggs."
name has stood for quality livestock nutrition for more than a
hundred years, since T. R. Moorman founded the company in 1885, in
Big Springs, Kentucky. Part of Tom Moorman's livestock was hogs,
which were not doing well. His concern over his ailing stock
prompted him to send a postcard to the newly-formed United States
Department of Agriculture in Washington D.C., requesting help.
received a formula, mixed it in the family coffee mill, and fed it
to his hogs. After consuming the mixture, his hogs showed marked
improvement. After seeing the results, Tom's neighbors and friends
urged him to mix the formula and sell it throughout the community.
Tom and his family mixed the product in their barn and sold it
from a horse-drawn wagon. A business was born!
MoorMan's saw a need to establish its own Research facilities.
Since then, our Research Team has pioneered so many new products,
it is considered to be the industry pacesetter. Today, our
Research Farms cover over 2,700 acres. In addition, we conduct
field-research trials where farmers and ranchers cooperate with
our researchers to challenge new products under a wide variety of
conditions. We also work with universities, state experiment
stations, federal agencies, chemical companies, and pharmaceutical
companies to conduct basic research.
Over the years, MoorMan's has pioneered many significant
advancements in animal nutrition, livestock parasite control,
quality control and feed manufacturing:
mineral-feed manufacturer to establish a research farm.
to develop practical iodine-analysis tests for feeds now used
throughout the industry.
to perfect a hog worm expeller to be used in feeds.
to produce mineral supplements in block form.
to make extensive use of pepsin-digestion tests to check
with a successful protein-vitamin-mineral block for self feeding
grazing beef cattle.
with a systemic insecticide in a complex mineral supplement for
beef cattle grub control.
feed manufacturer to market a self-fed protein block for
effective worm treatment of cattle on range or pasture.
to develop a highly palatable iron supplement for baby pigs.
feed manufacturer to market a mineral supplement containing an
insect growth regulator for grazing beef cattle to stop
development of horn flies in the harmless papal stage.
to develop a mineral block that divides into four quarters for

digestibility, and hindgut fermentation.
Provides natural-source vitamin E......
Shown to protect body tissues from oxidative damage. Vitamin
E is vital to immune system functioning and may be
especially important for working horses as they are more
prone to exercise-induced muscle damage. Natural-source
vitamin E is more bio-available than synthetic vitamin E.
