Pictured below: 0-copy beef
Meat from cattle having no copies of the inactive
myostatin gene. This meat has a lower lean-to-fat
ratio (it's fattier) and more marbling than meat
from cattle having one or two copies
of the gene.

is a USDA Research Report comparing the tenderness
levels of 0-copy, 1-copy and 2-copy beef. The
USDA confirms that all of the effects
on tenderness in the Piedmontese breed come from
Gene .... and not from any other genetic influence.

Years of research

calves, out of Angus-Hereford dams. The studies include
everything from calving, calf survival, and growth traits
through to carcass composition and meat quality.
have been truly remarkable. Production traits are good
- calving ease and survival is similar to the Hereford-Angus;
growth is again similar. But carcass composition excels
! Year after year the Piedmontese sired calves produced
lighter live weights, but equal or more amounts of retail
product per carcass than the much larger continental breeds,
such as Charolais. The efficiency in production is obvious.
All of these
calves, sired by 2-copy Piedmontese bulls, would have carried
1-copy of the myostatin allele. These 1-copy calves - year
after year - averaged the highest carcass dressing percents,
and highest retail product yield...even in comparisons
with the "other" muscle breed, Belgian Blue.

- and again, year after year, the Piedmontese sired 1-copy
calves produced the most tender beef product of all breeds
compared. The beef was also consistently the leanest of
all tested. Read more here ...
from Dr. Larry Cundiff, Research Leader, USDA MARC
“ Steaks from Piedmontese crosses contain less marbling
and chemical fat (3.8%) than those from other breeds
(eg. , 4.1% for Charolais and Gelbvieh crosses; 5.6%
for Hereford-Angus crosses) we have evaluated.
Since fat contains about 225 calories per ounce and lean
contains about 31.5 calories per ounce, beef from Piedmontese
crosses … has relatively low caloric content.
Caloric content of beef increases about 2.2 calories
per one percent change in chemical fat or about 3.3 calories
per degree of marbling.
As fat content of beef increases, percentage of protein
and water decreases. Thus, protein content is slightly
greater in low fat beef with a low fat content."
....EFFICIENT to PRODUCE
has proven that the Piedmontese beef (from 1-copy calves
sired by 2-copy bulls) is lower in the 'bad' saturated
fats and higher in the "good" poly-unsaturated
fats that today's consumer wants.
beef actually cooks faster - another fact
documented by the USDA. The unique attributes described
are all connected to the Myostatin gene this breed carries.
The Piedmontese Myostatin is unique among cattle breeds
- with research indicating that they are the ONLY breed
with this particular type of myostatin disfunction.
The simple direct
effect of heritability is this: using a 2-copy Piedmontese sire
on non-Piedmontese females ALWAYS gives you 1-copy calves. The
USDA research we quote - with the dramatic increase in carcass
composition and meat quality - is taken from 1-copy calves.
You can achieve these same results in one cross breeding season
using 2-copy Piedmontese bulls.

NOT, however, locked into specialty marketing niches.
When crossed with
the traditionally "fatter" British breeds, the Piedmontese
sired cattle will pay a serious premium in main frame markets,
due to these crossbreds ability to Grade Prime or Choice with
Yield Grades of 1 and 2. The
National Beef Quality Audit is encouraging producers to achieve
these goals in hopes of achieving 70-70-0 Beef (70% YG 1&2,
and 70% QG Choice or higher, with 0 "outs") Read the
report which shows that Piedmontese can achieve this in one

cautionary note, if you are building a web site and/or
creating sales materials for the sales of Piedmontese
beef (not cattle), you should be aware of the requirements
of the USDA.
Primarily, if you
are making any claims (i.e. natural, hormone/antibiotic
free, range feed, nutritional, Piedmontese,etc),
for the purpose of selling beef, you will need
to register your protocol with the USDA,
and obtain USDA approval.
All nutritional info that is used for sales purposes
need to be supported with documentation from the lab/testing
facility, based on your product. Feeding, myostatin
level, age, muscle type tested, etc will affect your
In addition, all labeling will need
to have USDA approval also.
You need to also consider, the processing plant needs to be federally
inspected, in order to sell out of State.
