June 7, 2002As you can see by reading this article [below] in this afternoon's Capital Times of Madison, word is slowly leaking out about what has apparently been a massive decade-long feeding of "supplements" (including meat and bone meal as mineral and protein) to wild deer in the heart of the "kill zone," the area of the WI Chronic Wasting Disease outbreak.
Apparently no one in the CWD research community has ever investigated the possibility that CWD may be spreading via rendered feed (mineral, fat and protein supplements), as happened in Britain with mad cow disease. This needs to be investigated immediately as a possible third means of infection for CWD, along with suspected animal-to-animal transmission and environmental contamination.
As you can see from the excerpts of two books below on feeding wild deer, there has been a huge push over the past 10-15 years of supplemental feeding of both game farmed elk and deer and wild deer to grow bigger animals with huge-boned antlers.
The implications for the US feed industry are staggering: a deadly TSE, a different strain than British BSE, has perhaps been spreading silently for a decade via contaminated US rendered byproducts still fed by the billions of pounds a year back to livestock in the US, and also exported globally.
The US refuses to adequately test livestock for TSEs. US feed regulations
are so abysmally lax (see the last chapter of our book Mad Cow USA available

"Deer supplementation has become a real growth industry within a relatively
short period of time. Consequently, there has been an explosion in the
different types of feed and feeders commercially available. ... There are
a few general guidelines which should be considered when supplementing with
a commercial feed. One of the most important -- and maybe THE most
important -- is the cost/benefit ratio if it can be determined, and whether
or not supplementation can be afforded at the levels necessary to enhance
reproductive success, body growth, antler growth, and longevity, and/or aid
during stress periods."
P.129
"With supplemental feeding, it becomes very easy to maitain artificialy high
deer densities and still obtain adequate results in terms of antler and body
growth."
P.130
"The planting of food plots specifically for use by deer is another growth
industry."
P.132
"Mineral supplementation to boost antler production has become another
growth industry in the past decade. To the authors' knowledge, there has
been no definite proof that mineral supplementation is an aid in producing
large antlers in white-tailed deer. Even if it does aid in antler growth,
it is not a one-item panacea for large antlers. ... In analyzing the
hardened antler itself, one finds that 40 to 50 percent of the antler is
organic material, principally protein. Calcium and phosphorus are the most
abundant minerals, in a ration of about two to one. ... All studies on
mineral supplementation to date have been on captive deer fed supplementally
and artifiically; therefore, results may or may not be applicable to a
free-ranging herd. ... The best method of supplementing minerals is to
pour the mineral into a hole or depression in the ground. In summary, the
three most common methods of increasing deer nutritional levels are growing
it from the ground (food plots); pouring it from a sack (commercial feeds
and minerals); and reducing deer densities to levels that ensure higher
consumption of preferred native browse by individual deer."

P.58
"Deer seldom use hard blocks until they melt with rainfall and the mineral
can be licked from the ground surrounding the block. providing a loose or
granular mineral is preferred. ... ...you should realize any time there is
concentrated feeding on the soil surface there is the danger of spreading
pathogens and parasites. Mineral supplied in a covered trough is the
preferred method. ... ...have it available all year long. There are times
when minerals probably are more important than others, particularly when
young deer are growing and bucks are beginning antler growth."
P.68
"...research on deer nutrition is limited. Our knowledge about deer at this
point is a combination of domestic livestock research along with practical
experience in raising deer and working closely with others who do the same.
Deer have a ruminant digestive system similar to cattle. However, they
cannot be considered 'little cows.' As free-ranging animals, deer are quite
different from cattle, with very different feeding preferences.
Unfortunately, as feeding deer has become more popular -- as well as
economically rewarding -- many feed producers simply have modified existing
cattle feeds to fit what they think deer need. In spit of published claims
to the contrary, there really are no substantive data on deer performance on
these commercial rations. ... However, some feeds developed for livestock
probably are adequate for use as a supplement."
P. 71
"Pick up any deer feed brochure and the focus always seems to be on protein
content. As with many human endeavors, more too often is considered better.
However, this is not always the case. After minimal levels are met,
incremental increases in protein levels do not equate to measurable
differences in antler score or body weight. ... Young and growing animals
have the highest need for protein. Research has suggested protein levels of
13-20 percent are necessary for optimum growth of fawns from weaning through
the age of 1.5 years. Also, milk production places increased demands for
protein on females. However, minimal levels necessary in the diet are still
unknown. Recent work suggest adult bucks can meet body and antler growth
requirements with as little as 10% crude protein. However, to meet the
requirements of all classes of animals you are supplementing, we suggest you
use a feed with a minimum of 15% crude protein."
P.72
"Unfortunately, minimum requirements of most minerals by deer remain
unknown. Varying results have been reported for those studied. However,
the major minerals we are concerned about in a supplemental feed are calcium
and phosphorus. Bot of these minerals are associated largely with skeletal
formation, including antler growth. ... As long as these minimal levels
are met, a dietary ration of calcium to phosphorus between 1:1 and 2:1 is
considered best for proper absorption and metabolism."
P.75
"Check to be sure the feed contains a minimum of 15% crude protein to meet
the needs of growing animals. Also, for deer feed, the protein level should
be made up of natural protein (sometimes designated NP). In other words,
protein derived from plant products. Non-protein nitrogen (usually
designated an NPN or urea) is not a good protein source for deer."
"Pelleted feeds are not normal deer food. As a consequence, deer often
have to be trained to accept pellets. Molasses is a common attractant and
has a high energy level."
P.84
"It costs a lot of money to feed you deer! ... The cost per deer is around
$100 per animal per year. ... Even when you have average annual rainfall
suitable for food plots, we suggest you install a feeder at each food plot."
P.96
"A free-choice mineral feeder should be located near each food plot. ...
We suggest you keep mineral available and let the animals 'decide' if it's
necessary."
None of three Ryan Road residents interviewed thinks that
a fruitful hunt can occur until fall or winter. The state Department
of Natural Resources wants to eventually kill all 15,000 white-tail
deer in a 361-square-mile area in Dane, Iowa and Sauk counties.
Andy Anderson has obtained hunting permits from the DNR
and plans to let people he knows and trusts hunt on his property. But
he does not plan to spend a lot of his own time hunting. "I am going
to shoot what I see but not just sit in the woods. I don't have
time," Anderson said. Deer will be much easier to find in winter
than during a leafy spring or summer, he said.
"Summer is a very busy time of the year," said Michael
Albert. "What little free time I have after work I like to spend with
my family. I have to consider my priorities. This is a hard time of
the year to get motivated for hunting. If I do get time I may
participate. I have permits and have communicated with people who
hunt here. It's up to them to decide. I haven't heard back."
Albert praised the DNR for being respectful to landowners
and not pressuring them to hunt or allow hunting on their properties.
David Frame plans to avoid the hunt altogether by going
fishing in Montana.
"I think the DNR people have lost their marbles. I lost
quite a bit of faith in them lately," he said. "A deer will be
standing on the trail now and hop into the woods and you can't see
them no more. There is a lot of brush. They just disappear. They shot
in the park and got eight deer."
As of 5 p.m. Thursday, 823 permits had been issued to
landowners, with more to be issued by Saturday. Each permit allows 20
additional hunters on the property. Additionally, 300 people have
requested government marksmen on their property. Of 4,600 letters
mailed by the DNR, 1,650 have been returned, indicating that
landowners want to participate in the hunt themselves, let government
marksmen do so or allow other interested hunters to do so. But not
all of them plan to eat the meat, even though the DNR will have it
tested if hunters say they want to consume it.
Anderson, who has a degree in meat and animal science
from the University of Wisconsin-Madison, was more aware of dangers
of prion diseases - the fatal brain diseases such as CWD that are
caused by abnormal proteins - than many others.
An industrial engineer who works as a project engineer at
Springs Window Fashions in Middleton, he has lived in the town of
Vermont for 27 of his 53 years.
"One thing going through my mind is, do you take the risk
and eat the meat? Traditionally, venison has been the main source of
meat for our family. But my wife Diane and I slowly came to the same
conclusion. It is not worth the risk to eat the meat," Anderson said.
Though there has been no known case of a human being
contracting a variant of CWD by eating deer, Europeans did die after
eating beef from cattle with mad cow disease.
"It was kind of a crapshoot. They ate brains and organ
meat and we generally do not. But sometimes lymph nodes get ground
into meat," he said.
Anderson noted that the town of Vermont area where
diseased deer were found is in the center of a quality deer
management area.
"A few years ago, you weren't a hero unless you shot
bucks. The premise of quality management is that you shoot mature
trophy bucks and let the young ones go. Some of my neighbors are
proponents of that. They are responsible people. The last seven or
eight years, there have been a lot of really big bucks out there,"
Anderson said.
But Albert does not think that quality deer management is
the culprit.
"We became involved with QDM around 15 years ago," he
said. "It started off as a grass-roots endeavor compromised of a few
dedicated landowners who felt we could do just a few things through
self-sacrifice to improve the quality of the white-tail herd in our
area."
Albert said the practice involves allowing smaller bucks
to grow older and harvesting more does instead, in order to balance
the herd by sex and age and control overpopulation.
Quality deer management also promotes hunter safety and
ethics, he said. They make sure that hunters see their target
clearly, so they don't leave a wounded deer to suffer or
accidentally shoot a fellow hunter.
Albert has also provided food to help deer through hard winters.
"Mineral and salt licks were indeed utilized, but now
with CWD in our area, we have discontinued this to prevent spreading
the disease through congregating deer," he said. "Perhaps
discontinuing this practice should be promoted or required by the
DNR."
Large bucks with big antlers are a byproduct of QDM, not
the goal, Albert said, adding that they do not support "trophy deer"
management.
"One of the negative things that has come out of this
disease is pointing fingers," he said. "One of the fingers pointed
was at people in quality deer management."
Albert, age 48, operates a dental lab in his home, doing
crown and bridge work for dentists. He and his wife Ann have three
children.
"For the time being I am holding off on eating deer meat.
I need to learn more before I take that risk. It is still in the
freezer. Our family eats about four deer a year. We did consume two
of them from the fall but we have stopped," he said.
David Frame, 63, who now raises timber on what was once a
dairy farm, blames the arrival of the disease on the DNR and state
agriculture department.
"I don't think deer quality management had anything to do
with it. I think one was brought in. They allowed animals to come in
out of an area that had it," Frame said.
Frame also thinks someone might have shot a deer in
Colorado, brought back the carcass, cut off the horns and skull and
thrown it in the woods, thus spreading contamination.

Reluctantly, hunt begins;
Landowners say it's bad time for
harvesting deer
June 7, 2002 Capital Times (Madison, WI) by Anita Weier
Those who live in the heart of chronic wasting disease territory --
in the town of Vermont where the first sick deer were found -- are
not excited about the weeklong kill that starts Saturday.
