Grass-Fed Beef Good for Business?

Most of the cattle raised in the Great Lakes region spend their lives in a feedlot, fattening up on
corn and other grains before becoming dinner themselves. But there’s a growing number of
organic farmers looking at putting their cows in the pasture. They say grass-fed beef is a healthy
alternative. Brad Linder has more:


(Sound of cows mooing)


Here on Natural Acres Farm in Millersburg, in Central Pennsylvania, 120 cows have their heads
to the ground. They’re chewing on tender shoots of grass instead of ground corn or some mixture
of grain feed.


Steve Shelley is in charge of marketing beef for Natural Acres. He says cows are designed to eat
grass, but most farmers today find it cheaper and easier to buy commercial feed made from grains
like corn.


“You know farmers nowadays. Well that’s the way their dads did it, so they’re doing the same
thing. It’s much easier to go out and dump a bucket of feed into a pen for that animal to eat than
it is for that animal to be out, to get the best benefit from the soil.”


And Shelley says another reason most farmers use grain feed is that it takes longer to raise cattle
on grass. Grain-fed cows are ready for slaughter within a year, but Natural Acres cows can take
six months to a year longer to reach the same size.


But Shelley says that convenience for the farmer comes at a cost to the cattle. Shelley says cows
raised on corn get sick more often than grass-fed cattle. As preventative measures, cows
traditionally have antibiotics mixed in with their feed and require frequent visits from the
veterinarian.


Cows on organic farms are naturally healthier. And since Shelley’s marketing his product to
consumers interested in “healthier meat,” the animals also don’t receive growth hormones or other
chemicals often found in commercial beef.


Natural Acres runs an organic foods shop on-site. But Shelley says the market for such products
is pretty small in rural Central Pennsylvania. Most of the beef isn’t sold here. Instead, much of it
is shipped to restaurants and stores, where people are willing to pay premium prices.


“In a grocery store, you may pay anywhere from a $1.75/pound to $2.00 for a pound of beef.
Retail, we get $4.09.”


Being able to charge more for beef is only one of the perks to raising cattle on grass. The farmers
who raise grass-fed beef don’t have to pay as much to the veterinarian.


“The animals rarely get sick. And I have talked to hundreds of people who raise animals on
pasture.”


Jo Robinson is author of the book, “Why Grass Fed is Best.” She also runs the website
‘eatwild.com,’ which compiles research on grass-fed cattle.


“The big surprise, I think – and this wasn’t known until about 1998 – is that an animal raised on
pasture has five times the amount of cancer fighting fat called conjugated linoleic acid, or CLA.”


Robinson says CLA helps prevent cows from developing tumors. There is some evidence
suggesting CLA has the same effect on humans, but it’s not yet clear if eating grass-fed beef is a
way for people to fight off cancer.


Robinson does point out that CLA is just one of the reasons there’s a growing demand for grass-
fed beef.


“Some people gravitate towards pasture finished meat because it’s free of hormones and
antibiotics. Some people are aware of the nutritional benefits. They like the fact that it’s lower in
saturated fat, higher in omega 3 fatty acids, higher in vitamin E, and a number of other
substances. It’s simply a healthier product all around.”


Robinson says she first started looking for American grass-farmers in 1997, and only found about
sixty. Now, she says, the market has grown to include at least ten times that number, which still
only represents a small portion of the American Beef Industry.


Paul Slayton is director of the Pennsylvania Beef Council, the non-profit organization charged
with promoting the state’s beef industry. Slayton says less than 1% of the state’s beef production
comes from grass farms. But he says those farms do fill an important role.


“I see it being a very viable part of our production in this part of the country, because we have
such an eclectic consumer group. And there are some consumers that just won’t eat anything else
but organic. And somebody’s going to be providing their food.”


As the beef industry is recovering from public concern over mad cow disease and e. coli bacteria,
Slayton says anything that convinces people meat is safe is fine by him.


And as for the taste of grass-fed beef, Steve Shelley from Natural Acres Farm says it might be
more familiar than many people think.


“Many times when I go and do a taste test at a store or something, a lot of the older people, when
they try it, make the comment: ‘This tastes like beef used to taste.'”


Shelley says the meat is leaner and can be tougher if cows aren’t fed a little grain before slaughter.
But Natural Acres is experimenting with different types of grass that might lend a more
consumer-friendly texture to the beef.


Shelley says it’s a combination of taste and nutrition that gets most people interested, even some
people who had given up on commercial beef altogether. Shelley tells one story about a man
who’s wife had banned meat from their house for five years.


“So he bought a hamburger and finally got her to try it, and at the end of the day, he gave me a high five, and he said, ‘I can eat beef
again! She’s given me permission to bring beef into the house!’ Well, that really makes you feel
good.”


So grass-fed beef is entering households that hadn’t seen any beef in a while for environmental
reasons or because of health concerns. While the beef might be a taste of days gone by, organic
farmers are getting better prices for their meat than even in the best of days past.

Curbing Nitrogen Pollution

Across the country, forests, streams and coastlines are getting extra doses of nutrients containing the element nitrogen.

Across the country, forests, streams and coastlines are getting extra doses of nutrients
containing the element nitrogen. Researchers say the long-term impact of these unwanted compounds on the environment could be serious. The Great Lakes Radio Consortium’s Daniel Grossman reports on some efforts to reduce nitrogen pollution:


A thunderstorm soaks the land and lights the sky. The electric jolts of the lightning change nitrogen in the air into compounds needed for plants to grow. Lightning, as well as microbes in the soil, converts annually nearly 100 million tons of atmospheric nitrogen into plant nutrients. Humans make the same compounds in factories and call them fertilizer, a mainstay of agriculture. Between these synthetic chemicals and a smaller quantity of related compounds produced when fossil fuels are burned, humans produce more nitrogen-rich nutrients than nature makes on the seven continents. University of Minnesota ecologist David Tilman says such extra nutrients are a concern.


“Right now half or more of the nitrogen we put on a farm field just washes through the soil and down into the groundwater into lakes, rivers, streams and into the ocean.”


This wasted nitrogen often travels great distances causing widespread damage. Tilman says on land, the nutrients cause exotic weeds to outgrow native plants. In the ocean, the nutrients cripple critical habitats. The ecologist says nitrogen pollution must be cut. One place to start is on the farm.


“We have to find some way to grow crops where the crops take up much more of the nutrients that we apply.”


(Sound of walking through grass. Quiet bird calls in background.)


Near Chesapeake Bay, farmer and agricultural scientist Russ Brinsfield walks across a patch of tall dry grass.


We’re on the edge of a field, about a sixty-acre field of corn, on the beautiful Eastern Shore of Maryland.


This field is a research plot at the Maryland Center for Agro-Ecology. Here Brinsfield is studying agriculture’s environmental impact. Chesapeake Bay’s waters have high concentrations of farmer’s nutrients, causing blooms of the toxic algae Pfiesteria. The pollution has also caused declines in sea grass beds. Brinsfield says solutions to the problem fall into two categories.


“The first series of practices are those practices that we’ve been able to demonstrate that by a farmer implementing them he can reduce his inputs without affecting his outputs… that at the end of the year have added profit to his bottom line.”


For instance, testing the soil’s nitrogen level before fertilizing. And splitting fertilizer applications into two doses rather than one so that nutrients are added only when plants need them. Such simple measures are good for environment and the bottom line. Brinsfield says in the last 10 years most farmers on the Eastern Shore of Maryland have cut fertilizer use this way. Then there’s the other category of improvements.


“We’re going to have to do some things-ask some farmers to do some things-that may cost them more to do than what they are going to get in return from that investment.”


For example, in the winter, many fields here are fallow and bare. That means top soil erodes when it rains, taking with it residual fertilizer. It wasn’t always this way.


“I can remember my dad saying to me, ‘every field has to be green going into the winter, Son.’ So all of our fields were planted with rye or wheat or barley. It served two purposes. First, the animals grazed it. And second, it held the soil intact.”


And intact soil retains its fertilizer. Such winter cover crops also prevent fertilizer loss by storing nutrients in plant leaves and stalks. This used to be dairy country and cover crops grazed by cows made economic sense. Now farmers mostly grow grains. Planting a cover crop could cut nitrogen flow from farms by 40 percent but it costs farmers about $20/acre and provides no economic benefit to them. Brinsfield says farmers need an incentive.


“For the most part, farmers are willing to participate and to do those things that need to be done, as long as they can still squeak out a living.”


To help them squeak out a living, the state pays some farmers to sow cover crops. The state also pays them to plant buffers of grass and trees that suck up nutrients before they leave the farm. Today farms in six states that are part of the Chesapeake’s huge watershed contribute about 54 million pounds of nitrogen to the bay. The goal is to cut this figure approximately in half by two thousand and ten. Robert Howarth, a marine biologist and expert on nitrogen pollution at Cornell University, says though ambitious, this target can be achieved.


“I think most of the problems from nitrogen pollution have relatively straightforward technical fixes. So the real trick is to get the political will to institute these.”


Howarth says much of the nitrogen problem could be eliminated with a blend of government subsidies and regulations. But more will be needed as well… solutions of a more personal nature.


(sound of Redbones Barbeque)


There’s a pungent, smoky aroma in the air at Redbones Barbeque in Somerville, Massachusetts. The crowded bistro serves up a variety of ribs, chicken, sausage and other meats, dripping with savory sauces. University of Minnesota ecologist David Tilman says when someone eats a meal they are responsible for the little share of fertilizer a farmer somewhere had to apply to grow a crop. If the meal is from farm-raised animals, like the heaping plates of meat served here, the amount of fertilizer is much greater than if it’s from plants.


“It takes from three to ten kilograms of grain to produce a single kilogram of meat.”


Tilman says if Americans ate less meat, they could dramatically reduce fertilizer usage. However, per capita consumption is rising. Meat consumption is on the rise globally as well. David Tilman would like that to change. He says if current trends continue, human production of nitrogen nutrients will grow to triple or quadruple what nature makes on all Earth’s lands. Professor Tilman says that in many places the impact on the environment would be catastrophic.

Creating Healthier Red Meat

While red meat has taken a beating in recent years from the health industry, a number of studies now indicate that it’s also possible for even red meat to have some health benefits. Scientists and farmers have found ways to put certain important fatty acids in chicken and pig diets. Now chicken, pork, and even eggs can have lower than average cholesterol. An organic farmer from Northern Illinois is participating in a study that’s trying to get beef to catch up to its healthier counterparts. If he succeeds, farmers across the Great Lakes might start varying their grain crops. The Great Lakes Radio Consortium’s Simone Orendain reports:

An organic farmer from Northern Illinois is participating in a study that’s trying to get beef to catch up to its healthier counterparts. If he succeeds, farmers across the Great Lakes might start varying their grain crops. The Great Lakes Radio Consortium’s Simone Orendain reports:

It’s feeding time on this sunny winter morning at Joel Rissman’s organic farm. Sixty head of cattle converge on the troughs that line the fence of their Northern Illinois cattle pen. The young cattle bob their heads in and out of the troughs that hold a mixture of pungent, sour hay and grain. They’re eating silage mixed with haylage.

“Think of sauerkraut, it’s along the same lines of sauerkraut.”

The dull yellow mixture of alfalfa hay and silage is made up of sorghum, cowpeas and soybeans that are mixed in the grain silo with an inoculant. The inoculant causes the silage to ferment quickly so it maintains its nutritional value. It raises the lactic acid content of the silage, making it easier for cattle to digest the food.

This silage-haylage mixture has a little extra in it. It has a pound of flax seed for each head of cattle.

Rissman says the flax seed will make the beef healthier than non-flax fed cattle. And it will taste better.

“What I’m striving for and my theory is that we can get the taste and flavor of a grain fed with the low cholesterol of a grass fed.”

Rissman is one of 10 cattle producers taking part in a study conducted by the Animal Sciences Department of Iowa State University. Researchers and farmers are looking at ways to raise healthy cholesterol levels in beef.

Grass-fed cattle produce healthy cholesterol called conjugated linolaic acid or CLA. The CLA is made up of trans-fatty acids. ISU Professor Allen Trenkle says increasing CLA in lab animals’ diets has protected them against plaque build up of cholesterol in arteries and certain forms of cancer.

But Trenkle, a lead researcher in the beef study, says consumers just don’t seem to like the taste of beef from grass-fed cattle.

“It’s just most of the beef that we have that’s been fed grain is bland. But that’s the taste that we’ve developed that’s what we want. They you introduce a different additional flavor and we say we don’t like that.”

Rissman explains his cattle were raised in a pasture from birth. He says by feeding them flax in the silage-haylage mix, he’s hoping to maintain the level of CLA that they produced when they fed on pasture. The cattle now feed exclusively on silage and haylage. Trenkle says flax seed has fatty acids that help increase CLA, but scientists are still learning why.

And Trenkle says there is a snag to the grain-fed experimentation:

“I would anticipate that it will be improved somewhat over conventionally fat animals, but the concentration of these fatty acids in beef’s very, very low. So feeding the flax may double it or increase it three or four times, but the concentration will still be low compared with the original oil in the flax seed.”

Trenkle says it will take a while to see if the experiment works. He says beef alone might not have a high enough CLA content to benefit consumers. Trenkle says it would have to be combined with a high CLA diet.

“I think just time alone will tell us whether the consumer is willing, how much the consumer is willing to pay for that. Will they want that product over the beef that has less CLA in it? We don’t know the answer to that question yet. In that sense, these farmers are pioneers.”

Rissman says he hopes it will work because he wants flax seed to be a prominent, viable grain again.

“Really the whole flax idea came from me wanting to find other grains. One of the big problems is, if you take food grade soybeans away from the organic farmers, probably 70 percent of those farmers would fail for lack of diversification, myself included. I wanted to find a way to diversify our crops.”

Trendle’s lab has its first batch of meat samples from grass-fed cattle. The team will begin analyzing the meat this month. Rissman says his cattle will be ready for sampling next year.

WHAT IS CHRONIC WASTING DISEASE? (Part 1)

Wildlife officials in the Midwest are battling the appearance of a deadly illness found in elk and deer. Called chronic wasting disease, or CWD, this ailment attacks an animal’s brain, slowly eating away healthy tissue. Several captive elk herds in the western U.S. and Canada have been infected with chronic wasting disease. Those herds have now been quarantined, but not before other animals from those herds were sold to farmers in 21 states nationwide, including several in the Midwest. The Great Lakes Radio Consortium’s Todd Melby has this first report of a two-part series:

Wildlife officials in the Midwest are battling the appearance of a deadly illness found in elk and deer. Called chronic wasting disease, or CWD, this ailment attacks an animal’s brain, slowly eating away healthy tissue. Several captive elk herds in the western U.S. and Canada have been infected with chronic wasting disease. Those herds have now been quarantined, but not before other animals from those herds were sold to farmers in 21 states nationwide, including several in the Great Lakes region. The Great Lakes Radio Consortium’s Todd Melby reports.


Chronic wasting disease is a neurological disorder. That means it affects the nervous system of elk and deer. It’s related to a number of other conditions, including scrapies in sheep and mad cow disease. Humans can also contract something similar — it’s called Creutzfeldt-Jakob disease.


All these conditions are related — and that’s making some health officials nervous. That’s because at least one, mad cow, can be transferred to humans. Dennis Stauffer is a spokesman for the Minnesota Department of Natural Resources. He says now more and more people are also keeping an eye on CWD.


“It’s been called the mad cow disease of deer. It is certainly similar biologically. There are also some important differences. Unlike mad cow disease, or CWD as we call it, we don’t yet have any evidence it is transmittable to humans. So that particular health risk is not confirmed.”


But that doesn’t stop people from worrying.


In the 1990s, mad cow disease in Great Britain triggered a similar ailment in humans, eventually killing dozens of people. But public health officials downplayed that possibility, leading to less vigilance in eliminating mad cow. Some people now say the same thing is happening here with CWD. Sheldon Rampton is the author of “Mad Cow U.S.A.”


“You are getting the same pattern of reassurances. The same pattern of government authorities and government scientists coming forward and not quite saying there is no danger, but saying they don’t see any evidence of danger. And then saying that in such a way that the public is led to believe that absence of evidence is evidence of absence.”


One of the problems is, little is known about the disease. Kris Petrini is a veterinarian with the Minnesota Board of Animal Health.


“We don’t know exactly what the incubation period is. We don’t know the youngest possible time an animal can get infected. The testing itself, right now, the only test we have that we can do is the animal has to be sacrificed and the brain tested.”


The outward signs of CWD aren’t exhibited until death is near. Again, Dennis Stauffer of the Minnesota DNR.


“Well, if you were to see a picture of one of these animals, they would be stumbling around, they would look wasted away. In advance stages, they would look disoriented, they would tend not to fear humans. They would look very, very sick and it would be very obvious that they are sick animals.”


Since learning that 36 elk from CWD-infected herds in Colorado and Canada were imported to Minnesota, state officials have set up a voluntary CWD surveillance program. All herds with exposed animals are participating in the program. Of the elk tested for CWD so far, none have had CWD.


(sound from Spooner, Wisconsin deer testing station: Cars on nearby two-lane highway.)


In neighboring Wisconsin, state officials are aggressively testing for CWD. On the opening weekend of deer hunting season, veterinarians took hundreds of brain samples from dead animals at locations throughout the state. In previous years, such efforts turned up no cases of CWD in the wild deer population, just like Minnesota. Ken Jonas is a wildlife biologist with the Wisconsin Department of Natural Resources.


“Right now, I’m not too concerned. If I were in Colorado or perhaps Wyoming or a state that was near to a chronic infection, I would be very concerned.”


While Kris Petrini, the Minnesota veterinarian, understands CWD hasn’t made it into the wild deer population, she says she wouldn’t be surprised to find it among the captive elk population in the state.


“No, not completely. Not with the number of elk we have and the amount of trading that goes on in the industry, I think it is highly possible that we will find chronic wasting disease.”


Six western states are home to elk herds with CWD infections. Elk farmers in another 15 states — including Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio and Pennsylvania — own animals from the original infected herds. So far, tests haven’t turned up any traces of CWD in herds with exposed animals in those states.

KEEPING AN EYE ON CHRONIC WASTING DISEASE (Part 2)

Several captive elk in Colorado have tested positive for chronic wasting disease. This fatal neurological ailment attacks an animal’s brain, slowly eating away healthy tissue. Chronic wasting disease, or CWD, has also spread to the wild deer population near the Colorado and Wyoming border. That’s prompted wildlife officials in the Midwest to begin looking for CWD in their wild deer herds. In the second of a two-part series, the Great Lakes Radio Consortium’s Todd Melby visited one such testing site in rural Wisconsin and filed this report:

The opening of the deer-hunting season in Wisconsin is a big day for Pauline Nol. But it’s not because she’s a hunter. Nol is a veterinarian. Instead of wearing a blaze orange vest, Nol sports a blue Dickie jumpsuit. She’ll need it to keep the blood of dead deer from staining her clothes.


(sound of medical instruments, followed by background sound of Nol and another vet moving instruments around on a table)


Nol and another veterinarian are arranging medical instruments on a folding table. It’s the kind of portable table you might find in a school cafeteria or church basement. Only today, the table is set up outside, in the parking lot of a Department of Natural Resources building just outside Spooner, a small town in northwestern Wisconsin.


In about a half hour, hunters will be pulling up in their pickup trucks to register deer they’ve shot just this morning. When they do, Nol, who works at the Department of Interior’s National Wildlife Health Center, will ask hunters if she might take a few samples from the carcass. The purpose: To check for chronic wasting disease.


Chronic wasting disease is a fatal neurological illness that is part of the same family of diseases as scrapies in sheep, mad cow disease in cattle and Creutzfeldt-Jakob disease in humans. CWD destroys a deer’s brain and is always fatal. Before death, the infected animal seems listless, confused and often stumbles around aimlessly.


There is concern among some people that CWD may be transmittable to humans. Yet many states in the Great Lakes region, such as nearby Minnesota, have just begun testing for CWD in wild deer herds. While it still seems limited to captive herds, officials are worried the disease could spread. Dennis Stauffer is a spokesman for the Minnesota DNR.


“The greatest problem, we think, in terms of not just the animals but in terms of human health is if this gets into the wild population. That would be, I think, very problematic. Because then once it’s no longer just limited to captive animals, then you have a real issue of how in the world do you get to it and eradicate it.”


In Wisconsin, veterinarians like Nol, have been testing dead deer since 1999. So far, the news has been good. No cases of CWD have been detected in the state’s wild deer herds.


(sound from deer testing station: Cars on nearby two-lane highway)


Back at the parking lot, employees are now ready to tag incoming deer. And that’s got Nol busy too. She strolls over to a couple standing next to a dead buck resting its head on the tailgate of a red pickup.


“Who got the deer this morning? That would be you? Congratulations. That’s great, that’s really great. So, we’re doing some sampling for looking at different diseases in the deer herd. So we’re wondering if we could take some samples from your deer?”


The pair agrees and Nol gets busy. The first thing she does is pull the deer’s head beyond the edge of the tailgate. And then she begins slicing through the fur and into the neck.


“What I’m doing is I’m making a cut in the neck just behind the jaw line. And that exposes the base of the brain, the brain stem and those lymph nodes we’re looking for.”


The lymph nodes are tested for bovine tuberculosis, or TB, a disease that’s been found in Michigan’s free-ranging deer herd since 1994. Wisconsin began testing deer for TB in 1996 and has yet to find an incidence of the disease.


The man who shot the deer is Tom Hack of Hartford, Wisconsin. Once the brain stem, lymph nodes and blood samples are analyzed back at Nol’s lab, Hack will be notified of the results.


There’s been no evidence linking CWD to humans. However, the state is testing deer for diseases and I ask Hack if that gives him pause.


“Well, sure. If I’m going to be eating the meat. Yeah, yeah it would worry me.”


“So, are you going to wait until you get the postcard back before you eat the meat?”


“No, I don’t think so.”


A little later, I catch up with Ken Jonas. He’s a wildlife biologist with the state DNR. This morning, he shot a deer himself. And now he’s tagging animals nabbed by other hunters. I ask him if hunters should wait until they receive their postcards back in the mail before eating the meat.


“No. Again, we consider all the deer currently to be safe in the state of Wisconsin. The monitoring is being done to determine if there is a problem at this point in time. We have no detects of either of those diseases in the wild herd.”


The reason for the testing, Jonas says, isn’t to let individual hunters know of a personal health risk, but to see if CWD has found its way into the state’s wild deer herds. For the Great Lake Radio Consortium, I’m Todd Melby in Minneapolis.

Tracking Livestock to Limit Diseases

Those worried about food safety say it’s time for a uniform animal identification system – one that could rapidly isolate animals suspected of carrying contagious diseases.

Those worried about food safety say it’s time for a uniform animal identification system, one that could rapidly isolate animals suspected of carrying contagious diseases. Wisconsin AG officials have taken the lead on this type of preventive action but will need the help of all the Great Lakes States to make it work. The Great Lakes Radio Consortium’s Mary Jo Wagner has more.


There’s growing consensus among agricultural officials that some type of universal animal identifier is needed to trace animals from birth to the marketplace. Especially in light of recent occurrences of “mad cow” and “foot and mouth” diseases in live animals overseas and the nasty form of e coli in meat products here. Wisconsin secretary of agriculture, Jim Harsdorf says the ID system started in Europe. Now it’s moved to Canada, where it’s mandatory, and Harsdorf says Holland has a central database containing information on all the nation’s animals.


“It’s housed in one location and the producers within 48 hours have an animal ID’d after it’s born and that animal ID stays with it for life.”


Federal officials in the United States have been slow to implement such a system though, so Harsdorf says state officials are working to come up with one. It might be tied to different identification networks that farmers already use to keep production and reproduction records, herd health, vaccinations and the location of cattle that are sold, or it could be a totally new system that keeps some or all of those records on one central computer database managed by state, private or non-profit organizations.


Wisconsin state veterinarian Clarence Siroky says public feedback surprised them. State officials were expecting farmers to want only a voluntary system but what they found at public meetings was that producers want a more comprehensive mandatory system nationwide


“We move cattle all over the United States rapidly…we can have one cow at least touch 27 other states within a week…one pig can touch 19 other states within 24 hours.”


For those reasons, Siroky says, all animals will have to be included, not only cows, but sheep, horses and pigs. In England for example, cows are identified, but sheep are not, and he says sheep were implicated in the rapid spread of foot and mouth disease there.


That concerns Ted Johnson. He’s a Wisconsin dairy farmer who likes the idea of a universal identification system because it would quickly pinpoint the location of animals that might have come in contact with a disease.


“If in the event of an outbreak of some highly contagious disease, it could be stopped very quickly and we wouldn’t have to have wholesale slaughtering of cattle.”


Still Johnson says many farmers are concerned about how much the ID would cost, who would maintain the records, and who would have access to them.


“The worst case scenario would be if that information is released and there is some doubt about the information or if the information is used in an incorrect manner, the perception can be there’s a problem on individual farms.”


State veterinarian Clarence Siroky says that’s why input from farmers, processors, privacy advocates and consumers is important as the technology is developing.


Still to be decided is the type of animal ID that would be used. Siroky says it could be a tag placed on the animal’s ear. However, some animals already have so many different ear tags, he says one ear can look like a Christmas tree. Other possibilities include a computer chip or other type of recyclables monitor placed inside an animal.


Meanwhile, AG secretary Harsdorf says the records included in a computerized type of system could be very beneficial to consumers at the supermarket.


“At some point in time, you’re gonna have the ability to go through a grocery store and see up on a screen when you buy that package where it came from, a picture of the operation — it’s almost mind boggling to see what could happen down the road.”


Still, farmer Ted Johnson worries all the talk right now about the need for animal identification might create a consumer backlash.


“I feel as a producer our food supply is very safe. I don’t want the perception to be that an animal ID program is being instituted because we have a problem.”


But a potential problem without plans to deal with it could create havoc for the agricultural industry, and so far veterinarian Siroky doesn’t know when a system with wide support might be in place. He does say animal health officials are on high alert for the appearance of any contagious diseases. At the same time, he says even if Wisconsin comes up with a proactive plan, unless other states adopt a similar identification method, any tracking system would have limited effectiveness.

Eco-Cows Munch on Invasive Plants

Cattle that love to eat thorny shrubs and nasty weeds are proving they can clean up areas infested with invasive plant species. The Great Lakes Radio Consortium’s Mary Jo Wagner reports.


For years, land managers have been trying to find better ways to control particularly troublesome plants. Invasive species such as multi-flora rose, prickly ash and wild parsnip used to be held in check by natural fires, or grazing by bison and elk. But ever since wildfires have been mostly controlled, and elk and bison populations have plummeted, many invasive species in the Great Lakes region have been growing out of control. So researchers have been looking for other ways to fight these invaders. At the University of Wisconsin, researchers have been testing Scottish Highland cattle on some fields containing invasive species. Consultant Martha Rosemeyer says the preliminary results look promising…


“One of the things we’ve found out by following the cattle is they really like wild parsnip when it’s young. Out of a field of grass they’ll identify and hone in on the wild parsnip and eat the whole patch of it.”


One of two farms testing the cattle’s weed eating potential is owned by Peter Rathbun. He says on one of the test plots, the parsnip was so high and thick, biologists wouldn’t go in to take samples.


“I was a little concerned, well are the cows going to go in and eat it and get sick, but they went in and ate it and they loved it.”


Rathbun has various weed and brush problems or “junk” as he calls it on 120 acres, including prickly ash, hawthorn, gooseberries and other plants that produce large thickets. He was one of the first farmers in Wisconsin to start raising the highland cattle several years ago and now has around forty animals eating weeds on half his farm. His goal is to return some o the land to its original oak savannah status. So far on his fifteen test plots with and without cattle, the results of grazing Scottish cattle are positive.


“It’s so wonderfully obvious what’s happening because here’s three strands of electric fence. On one side you can walk right through the woods…its no problem – you can see everything there. On the other side it’s dense, you don’t even want to think about walking through it. And this is only after 2 rotations.”


Rotating means moving groups of up to nine cattle around on once-acre test plots. The cattle spend two or three days on select plots each month throughout the summer. Martha Rosemeyer says researchers were interested in the breed of cattle because in Europe, they’re referred to as “eco-cows.” That’s because of their unique ability to eat plants that have inch-long thorns.


“They’ve got really tough tongues – they wrap them around these and pull – so they pull these things up like prickly ash leaves off and aren’t really bothered by thorns. They actually like thorns to rub and scratch…they’ll lean on things and scratch and they’ll break them and change the vegetation in that way too.”


Peter Rathbun says it didn’t take long for his cattle to tackle a patch of prickly ash after the gate into one test plot was opened.


“They ran over to it and started eating the actual bush. And I loved to see the reaction of some of the graduate students who’ve been working on this for a very long time. In their heart of hearts they really had some doubts whether the animals were really going to like to eat the junk.”


Once results are in by the summer of 2003, consultant Martha Rosemeyer says researchers may have a better idea of how effective the cattle will be at permanent eradication of unwanted plants.


“Certainly if you knock down a plant by taking off it’s above ground vegetation a number of times, it weakens the plant and it eventually will die. That’s what we’re hoping will happen but we’re not sure we need to test this and see the results…it’s speculation at this point.”


By comparison, Rosemeyer says on Department of Natural Resources land, a few test pilots were grazed and burned earlier this year to compare the weed control with the Highland cattle. It turned out that combination was too destructive and the burning was discontinued.


Meanwhile, not only do these animals eat through the bad stuff, but they also provide great hamburgers. Rathbun sells the meat as a low fat, very tasty source of protein.

Farm Belt Braces for Impending Drought

  • Ponds and lakes in some areas of the Midwest are the lowest they've been in more than 35 years. Some cities are implementing water use restrictions. Some farmers are concerned there's not enough subsoil moisture for crops to use during the hot summer months.

The farm belt is short on rain. Since last summer, much of the
Midwest has been getting below normal rainfall. Lakes and rivers are
low. Long-range weather projections are not promising. Farmers and
communities that rely on reservoirs are concerned. The Great Lakes

Farmers Go Online

These days, all kinds of businesses — from automakers to hotel chains — are going on-line to do their buying and selling. By meeting through electronic marketplaces, they hope to save time and cut costs. And as the Great Lakes Radio Consortium’s Wendy Nelson reports, even farmers are giving it a try:
