New methods of identification have made it easier in recent years to pinpoint such toxins. But determining whether they are the source of health problems in a dairy herd--and if so, which mycotoxins--is still difficult.
Earl Fournier of Swanton, Vermont, has had haylage test positive for mycotoxins in the past. He's added an adsorbent to counteract the effects and works at harvesting and storing feed better. But he says it's hard to tell how mycotoxins affect his 80-cow herd. "You can't really measure the effects because there are so many other factors involved," Fournier says. "It could be environmental factors, too."
Gotlieb is trying to solve part of that puzzle by studying the physiological systems of a dairy cow and how they are affected by fungi common in silage. The first system he is looking at is the rumen, the most important part of a cow's stomach. Thousands of different microorganisms flourish in the rumen, breaking down and digesting what the cow eats. Gotlieb's approach is to measure how one mycotoxin can affect those microorganisms and, therefore, the rumen's ability to digest forage.
Mycotoxins such as vomitoxin and fusarium have been shown to contribute to spoilage in cattle feed. But Gotlieb suspects that one of the most damaging culprits may be strains of penicillium resistant to the acid in silage. "If we can find the toxins with major effects, then we can look at management strategies to prevent spoilage," he says.
Penicillium fungi, like other destructive fungi, are already present in crops coming in from the field. If fermenting feed, called silage, isn't stored properly, the molds can continue to grow, eventually causing the feed to spoil.
Another management technique is to add an adsorbent to the feed on farms where there are possible mycotoxin problems. These adsorbents, such as sodium bentonite, can bind and remove some of the mycotoxins from the feed--but they don't always work.
UVM is the only place where the U.S. Department of Agriculture is sponsoring research on penicillium-related mycotoxins. But Gotlieb also collaborates with Dr. Peter Erickson, head of the Department of Animal Science at University of New Hampshire (UNH), on the research. First, Gotlieb isolated about 50 strains of penicillium from moldy silage found on Vermont farms and is growing these isolates on fermenting silage in his laboratory. Then, Erickson will test their effects on an artificial rumen in his laboratory at UNH. Gotlieb and Erickson are also investigating the ability of different adsorbents to counteract penicillium contamination.
Craig Altemose, UVM Extension crop specialist and a former master's degree student of Gotlieb, has also contributed to the effort to control mycotoxins. In his master's work, he found that if you reduce damage from the European corn borer in corn, you should see less incidence of fusarium mold and the mycotoxins like vomitoxin that are produced by the mold. As an Extension crops specialist, Altemose uses that knowledge to advise farmers on ways to fight off mycotoxins by controlling corn borer and other pests primarily through crop rotation, by harvesting and storing silage properly and by using adsorbents if they suspect a mycotoxin problem.
With such efforts, they are working to save the Vermont dairy industry as much as $60 million a year and to solve another piece in the mycotoxin puzzle.

Many of the charitable gifts to the College of Agriculture and Life Sciences (CALS) within the past 12 months have much in common. Of the 850 donations between October 1, 1999 and October 1, 2000, a significant number have been either for the Proctor Maple Research Center (PMRC) or the UVM Morgan Horse Farm. The response to special fundraising campaigns for each has been very strong, resulting in a robust finish to the PMRC Endowed Research Fund drive and a rousing start to the 50th anniversary campaign for the UVM Morgan Horse Farm.
A $2.5 million campaign for the PMRC was launched in 1997 in conjunction with the 50th anniversary of its establishment. One of the campaign's objectives--a $500,000 endowment fund for maple research--has been completed ahead of schedule, thanks to the stimulus of a $200,000 challenge grant and a flurry of gifts of all sizes. CALS officials took pride in announcing the fulfillment of this goal before a receptive audience of 400 maple enthusiasts at the International Maple Syrup Institute and North American Maple Syrup Council convention in late October. Additional support is being sought to fund a $2 million endowed professorship in maple biochemistry.
Like PMRC, the UVM Morgan Horse Farm has a storied history that spans 50 years, a demonstrated commitment to excellence, and a need for more stable sources of funding. The UVM Morgan Horse Farm's $2 million campaign kicked off in fine fashion this summer with a fundraising dinner and benefit auction that honored director emeritus Dr. Donald Balch. Roughly $60,000 was raised at the dinner held in conjunction with the New England Morgan Horse Show in Northampton, Massachusetts. The 50th anniversary campaign for the UVM Morgan Horse Farm will encompass several special events at Morgan Horse events around the country over the next year, including a gala celebration in Weybridge, Vermont, next August. The UVM Morgan Horse Farm campaign seeks $1.5 million for endowment support (the fund named to honor Dr. Donald Balch), and $500,000 for facility improvements. Over $300,000 in cash and pledges has been received to date!
For more information about making a gift in support of these major campaign objectives or other projects of importance to CALS, please contact Howard Lincoln.

Message from Dean A. John Bramley
Several new faculty have joined us over the last year and are already making great contributions in their departments. We are further strengthening our first-year programs and have appointed Dr. Tom Patterson to take a special responsibility for this area to help maximize the success of our incoming students. Furthermore, we have totally revised our core curriculum around the knowledge, skills, and values required for our students to be successful in their future careers and contributions to society.
The UVM/Vermont Technical College (VTC) Dairy Management Program has really started to get off the ground under the leadership of Don Maynard. Last spring several of these students were the first to study for the intensive hands-on management semester at Miner Institute in Chazy, New York, and pronounced it a great success. We now have 18 Vermont students enrolled either at UVM or at VTC supported by scholarships from the Vermont legislature. However, we need to work hard to build our scholarship support programs, not only for this activity but for all our programs, to ensure that we not only attract the best students but also help make education affordable for all our students.
I would also like to congratulate our outstanding faculty on their research successes. In 2000, research funds increased 64% compared to 1999.
We still have lots to do and plenty of exciting plans. Thank you all for your great support and interest in the College and its future.
