The focal point of our annual spread is often a juicy, tasteful turkey with stuffing and all the trimmings. Thanks to people like Karl Nestor, an animal scientist at the Ohio Agricultural Research and Development Center's Wooster campus, turkeys are growing bigger and betterQbenefiting producers and consumers. Turkeys are an important part of Ohio's agricultural industry. In 1996, Ohio's 6.8 million birds brought in $97.6 million in cash receipts. As a result, Ohio ranks 10th in the nation in turkey production. Nestor uses DNA fingerprinting to improve genetic traits in turkeys. The three major turkey breeders in the world have been supplying the industry with turkeys that grow fast with larger breasts. That's great, except the turkeys had a hard time walking. "When the body weight and breast size increased," Nestor said, "the legs of the turkeys weren't strong enough to support the weight of the bird." That problem led to leg problems and even death. Nestor used genetics to develop turkeys with stronger legs. As a result, there are larger, meatier turkeys available to consumers. With one problem solved, Nestor has moved on to disease control. He now uses DNA fingerprinting to help prevent diseasesQlike fowl cholera and Newcastle disease virus. Fowl cholera is severeQany number of birds could die without showing any warning signs. The disease attacks the major organs. If the bird survives, the disease manifests in the joints, causing problems that eventually lead to death. Newcastle disease affects the respiratory system. The mortality rate isn't as prominent, but growth rate is affected. In adult birds, the disease causes a reduction in eggs as well as misshapen eggs. "Vaccines have been developed for Newcastle virus," Nestor said. "The only problem is that the most effective vaccine contains a live virus -- you can't vaccinate just one unit, you have to do them all." That's a drawback for producer pocketbooks, but the impetus for a goal for Nestor. "If your turkeys have genetic resistance to the disease, you don't need a vaccine," he said. Developing turkey disease resistance isn't the only serving on Nestor's plate. Recently, he had an unusual development in Japanese quail. Because quail react similarly to turkey but reproduce more quickly, Nestor and his colleagues conduct many of their turkey studies on quail. While studying body weight and how it affects reproduction, the scientists discovered large tumors in the female birds. Working with Mo Saif in Food Animal Health Research Program, they determined the birds had smooth muscle tumors. The tumors were up to 10 percent of their total body weight. "A scientist at the University of Georgia has a line of quails he uses for selective growth studies," Nestor said. "We examined the DNA fingerprints of his birds and our birds to see if they were related. They were not, but his birds also had tumors." In fact, about 75 percent to 85 percent of the female quails from growth-selected lines had at least one smooth muscle tumor. "The tumors didn't cause a great deal of harm to the birds," Nestor said. "The tumors may cause the birds to quit producing. When that happens, estrogen levels decrease. Without enough estrogen to grow, the tumors slowly disappear." Smooth muscle tumors are often found in human females. Like those in the Japanese quail, this type of tumor depends on estrogen to grow. "These findings have a biomedical aspect," Nestor said. "We think these tumors are directly related to body weight." Nestor plans future studies in conjunction with scientists outside the College of Food, Agricultural, and Environmental Sciences to determine what causes the tumors and how this agricultural research may help humans. BAN IGNORED PRESSURES REPORT November 4, 1998 The New Zealand Press Parliamentary Commissioner for the Environment, Dr J. Morgan Williams was cited as writing in a report that financial and emotional pressures on farmers with rabbit infestation were not adequately considered when the rabbit calicivirus disease was banned, arguing that since then there has been too much criticism of the perpetrators of the release, and too little consideration of why normally law-abiding rural communities sanctioned its release. The story says that RCD was illegally released in New Zealand in 1997 after a decision in July that year by the Ministry of Agriculture to ban its release. Dr Williams was quoted as writing, "Most members of a society uphold laws they consider to be fair and just. Biosecurity laws are particularly dependent on public acceptance of their fairness and value ..." The report describes the illegal release as a "systems failure" akin to the 1998 power crisis in Auckland. Since 1979, policy changes had shifted the cost and responsibility for rabbit control to local councils and landowners to the extent that by 1997 farmers were bearing the full expense. Over the same period, both governments and researchers were placing increasing emphasis on biological controls rather than pesticides, heightening farmer expectation that these would be introduced. FARMERS WARNED AFTER STAG GORES MAN TO DEATH November 5, 1998 PA News Chris Parkin An elderly man has, according to this story, been gored to death by a stag on a deer farm in the Irish Republic while feeding deer on a farm run by his son in Co Limerick. The incident - believed to be the first of its kind - prompted a warning today from a deer-rearing experts that stags could be dangerous during their rutting season. Michael O'Dowd, of Teagasc, the Irish government-backed agriculture advisory body, was cited as saying that farmers should only enter areas where stags were being kept at this time of the year under exceptional circumstances, adding, "We advise deer farmers to remove the antlers and stay away from stags when possible." TAINTED DOG FOOD BLAMED ON CORN November 3, 1998 San Antonio Express News J. Michael Parker Express-News Staff Writer Dr. Catherine Barr, assistant toxicologist at Texas A&M University's Veterinary Medicine Diagnostic Laboratory was cited as saying that tainted dogfood linked to the deaths of about 25 dogs in Texas in the past two months has been traced to moldy corn damaged by insects during last summer's drought. Tests revealed the culprit as aflatoxin B1, a mold toxin that gets into kernels of corn that cracked because of insect activity and extreme dryness. The story notes that a pathologist noticed lesions suggesting the presence of aflatoxin appeared repeatedly in the liver samples. Douglas Cahill, chief executive officer of Tennessee-based Doane Products Co., which manufactured the dog food, was cited as apologizing for the dog deaths, adding, "We first learned of one isolated incident and got data back last Friday identifying aflatoxin as the cause of death. We've identified six pet owners with a total of 12 dogs, but now we know 25 dogs have died. We've met with the six owners we've identified to find out what they fed their dogs and where it came from. Our goal is to meet with every pet owner." Cahill added that a recall affects all of Texas and Shreveport, La., but added that few products manufactured in July and August still are on the shelves. The affected foods probably came from one batch, he said. Anyone with a product included in the recall should return it, in the original packaging, to the store where it was purchased. It will be replaced at no charge, Cahill said. "Our first concern is for the safety of family pets," he said. "Even though the problem appears to be limited to a very small amount of dog food, we are recalling more than enough production to assure we remove any pet food that may be a problem." Cahill said his company has intensified product testing. REFINING ETHICS November 7, 1998 New Scientist Penny Hawkins of the RSPCA based in Horsham, West Sussex, UK, writes in this letter that she was delighted Inside Science (Number 114, 17 October) highlight the ethical dilemma associated with the use of animals in scientific research. However, the article contained an error concerning a very important concept. "Refinement" is not "extracting the maximum information from the minimum number of experiments". This is actually another example of reduction. Refinement means minimising pain, suffering and distress during and after experiments and improving welfare, which is a legal requirement of the Animals (Scientific Procedures) Act 1986. Animal husbandry can (and should) also be refined beyond the minimum requirements of the Act by giving all animals an appropriate and interesting environment to live in. Ethical decisions therefore need to be made, not only about whether to use animals and how many to use, but also about how they will be used and whether they can be housed and cared for so as to minimise both physical and psychological suffering. This can have an immediate positive impact on the welfare of laboratory animals for as long as their use continues. ANIMALS AND ANTIBIOTICS November 3, 1998 CBC News and Current Affairs PETER MANSBRIDGE: An alarming new report in a Canadian medical journal today about animals and antibiotics. It says far more antibiotics are given to animals than people, hundreds of times more. And it calls that a major part of the superbug problem. Kelly Crowe explains. KELLY CROWE: For these Alberta cattle, dinner is part barley, part vitamins and minerals and part antibiotics, in this case to keep them from developing pneumonia. BOB THORLAKSON / THORLAKSON FEEDYARDS: Through the appropriate use of antibiotics, we reduce both sickness and death in our cattle. CROWE: Across the agricultural industry, farmers are using antibiotics to treat and prevent disease and in some cases to simply promote growth. But some scientists say giving animals antibiotics may be hazardous to human health by helping to create dangerous bacteria that are increasingly resistant to drugs. It's an accusation made today in a review published in the Canadian Medical Association Journal. Dr. ALLISON McGEER / MICROBIOLOGIST: The fear is that if we keep using them inappropriately that we'll lose them when we need them and they're very important. CROWE: Researchers say bacteria exposed to antibiotics in animals are learning how to resist the drugs and then finding their way into the human food chain. Researchers say that bacteria is causing infections in people; infections that are immune to traditional antibiotic treatment. But veterinarians who work in the feedlot industry say they aren't persuaded that there's a direct link between antibiotics in animals and drug resistant bacteria in people. They want more evidence. And they say people are misusing antibiotics too. TIM GUICHON / FEEDLOT HEALTH MANAGEMENT SERVICE: I'm not saying there is or there isn't a link. It's unclear but the stakeholder including human medicine and the medical profession also need to deal with their role in this whole thing as well. So it's a much more complex issue. CROWE: But researchers say the evidence is overwhelming. That misuse of antibiotics around the world is creating dangerous strains of bacteria and that reducing antibiotic use is the only solution. Dr. JOHN SPIKA / HEALTH CANADA: We are much better off to try and control it at this point in time than we're going to be five or ten years down the pike. CROWE: The scientists admit it's a complex problem requiring international co-operation and fundamental changes in both agricultural practices and in the way human disease is treated. But they say as more bacteria become resistant to drugs, it's a problem that's becoming increasingly urgent. Kelly Crowe, CBC News, near Airdrie, Alberta. NEW VET RULES CONSIDERED November 2, 1998 Farm and Country ROBERT IRWIN New vet rules need to be established, according to this story for extra-label drug use (ELDU). It happens every day on many farms when more antibiotic, than is recommended on the label of the bottle, is used to treat an animal. And sometimes a disease or condition calls for a drug licensed for another species or purpose. Draft regulations could, according to this story, provide both farmers and vets with peace of mind for such extra-label use. One problem is no one knows for sure how long it takes before it's safe to consume milk or meat from animals undergoing so-called extra-label drug use (ELDU) treatment. Withdrawal times for drugs used in an approved fashion are supposed to be based on careful science. Variables can include the age and condition of the animal. Dr. Dale, a board member of the College of Veterinarians of Ontario (CVO), was cited as admitting that he has used ELDU on cattle in his own practice, adding, "At times I questioned the withdrawal times." He was cited as saying that it's time the College regulated so-called extra-label drug use. In addition to residues, he cites growing public awareness of resistant strains of salmonella, E. coli and campylobacter. Scott was further cited as saying that he hopes his proposals will eventually be adopted by the Canadian Veterinary Medical Association. The first challenge, though, is deciding what exactly "extra label" means, adding, "A definition definitely has to come out of this study." If for no other reason than harmony with our trading partner, this will probably resemble one set out by U.S. officials under the Animal Medicinal Drug Use Clarification Act enacted almost two years ago. This story explained that the AMDUCA definition includes "use in a species not listed in the labeling, use for an indication [disease or other condition] not listed in the labelling, and use at dosage levels, frequencies or routes of administration other than those stated in the labeling." U.S. vets can't prescribe an extra-label use to simply boost production. FEDS MAY HIKE LIVESTOCK COMPENSATION November 5, 1998 Western Producer Barry Wilson The federal government is, according to this story, considering a significant increase in the maximum compensation payment for cattle ordered destroyed because of suspicion of a reportable infectious disease. Andr Gravel, acting vice-president of the Canadian Food Inspection Agency, was cited as telling a House of Commons committee last week that Health of Animals Act compensation levels are being reviewed. He said in an interview after the Oct. 20 meeting, that a committee of industry and government also will review compensation for other animals covered, including cattle, pigs and horses, adding, "I don't think cattle will be doubled but I do think there will be a significant increase." If the recommendations of a consultant are accepted, the levels of compensation would be reviewed regularly. And the system of determining compensation likely will change. ANIMAL HEALTH; PREGNANCY COMPLICATIONS November 5, 1998 Western Producer Jeff Grognet Cows entering their final trimester of pregnancy are, according to this story, at risk for complications. Specifically, they may lose their fetuses or they can develop dropsical condition. This story explained that a common problem of late pregnancy is fetal mummification. Though the herd incidence is usually less than two percent, it can be much higher in feedlot heifers that have failed to expel their fetuses after being given medications to induce abortion. When the fetus dies, the fluids are absorbed by the dam. The fetus and the membranes become dehydrated leaving a dark, leathery mass, which is nothing more than a skeleton covered with dried skin. Cows with mummified fetuses do not become ill. Because a live calf is needed to stimulate parturition, a mummified fetus will not be detected until the cow fails to calve. Once discovered, a mummified fetus must be removed. Administering prostaglandins to the cow usually causes its expulsion in two to four days. Cows that don't respond need surgery. Once a cow has recovered, it can be rebred without complications because the problem involved only the fetus. Fetal maceration occurs when the fetus dies from an infection and is not aborted. The fetus is slowly decomposed by bacteria until all that is left is a compact mass of bones. The hallmark of fetal maceration is the presence of pus discharging from the vagina. There is no good treatment for maceration because bone fragments often remain embedded in the lining of the uterus. Affected cows should be culled because they are not likely to conceive again. Dropsical conditions occur in late pregnancy and are, according to this story, caused by excess fluid accumulation in the fetal-placental unit. The fluid can be either in the allantoic membrane, which stores urine from the fetus, or in the amnionic membrane, which surrounds the fetus. The amnion should contain about six litres of fluid at the end of gestation. This fluid is derived from the calf's saliva. The volume is kept in check when the fetus swallows. If there is a congenital defect that prevents swallowing, fluid will build up to as much as 150 litres. When large volumes of amniotic fluid accumulate, the cow's abdomen distends and looks pear-shaped. When lesser amounts build up, the condition may not be noticeable until calving. Cows with hydrops amnion can be rebred as long as the fluid did not cause permanent damage. Hydrops allantois is the more common condition, accounting for more than 90 percent of dropsical conditions. Urine produced by the fetus flows through a small tube in the umbilical cord into the allantoic sac. A normal volume is about 9.5 litres in late pregnancy. In hydrops allantois, as much as 200 litres of urine will accumulate. Surprisingly, this is not the result of poorly functioning fetal kidneys. The problem is a placental abnormality. Many older cows have a deficiency of caruncles (the sites on the uterus where the fetal placenta attaches.) Loss of caruncles can result from a prior uterine infection, from the forceful extraction of a fetus, or from pulling hard on a retained placenta. It is, according to this story, believed that a deficiency of caruncles upsets the fluid balance in the uterus/placenta unit. The excess accumulates in the allantois. Hydrops allantois develops rapidly over a period of three weeks in contrast to the slow accumulation of fluid in hydrops amnion. As fluid builds up, the cow develops digestive symptoms (lack of appetite, constipation) and may have trouble breathing. The prognosis for a cow with hydrops allantois is poor so immediate slaughter is recommended. If the cow is allowed to live until delivery, there is a possibility that her uterus will rupture or support ligaments that hold her uterus in position will break. She is also at risk for hip dislocations or hind leg fractures due to the massive weight she carries. The other option is to induce abortion or do a caesarean but the high rate of complications can make these choices impractical. SHOW RING SHENANIGANS November 2, 1998 Farm and Country DON STONEMAN Canadian breeders can, according to this story, take pride in their genetics, which figured favourably at last month's World Dairy Expo in Madison, Wis. They could have done without the publicity over a Canadian drug, Liquamast Aerosol, that has allegedly been used for cheating in the show ring. The aerosol pushes a drug up into a quarter through the teat. It can also be used to blow up a cow's udder, giving it just the right amount of roundness and uniformity desirable in the show ring. And the latter is precisely what some breeders have been accused of doing at dairy shows in the U.S. Dr. Terry Howard, superintendent of the dairy cattle show at Madison, was cited as saying that the drug is Canadian and has never been approved in the U.S., but show ring cheating isn't a Canadian problem. The product has found its way into the hands of breeders from elsewhere, as Liquamast is no longer being marketed in Canada. Pfizer took it off the Canadian market last spring. No penalties were laid against breeders at the World Dairy Expo for using unethical and perhaps illegal methods to inflate cows udders to make them look better in the show ring. SOUND SCIENCE IS A GOOD ANTIDOTE TO DISSENSION: AN EDUCATOR DETAILS CONTROVERSY SURROUNDING HEALTH CANADA, FROM MILK SUPPLEMENTS TO APPLE CIDER. November 4, 1998 The Vancouver Sun A17 Nov. 5/98 Hamilton Spectator/K-W Record Douglas Powell GUELPH, Ont. -- Health Canada can take some immediate steps to stop the hemorrhaging of credibility and restore confidence to the Canadian public. For two months now at least in this latest incarnation allegations have swirled around Health Canada regarding suppressed scientific studies, managerial incompetence and valiant researchers desperate to go public. But the bureaucratic response we're seeking expert advice, we're consulting with Canadians, we're re-engineering ourselves to become more excellent are falling on deaf ears. And rightly so. What's to do? In early September, allegations surfaced that scientists within the health protection branch were being forced to approve veterinary products such as recombinant bovine somatotropin (rBST) in the absence of adequate human health studies. A mysterious study alleged that some 10 years ago rats injected with high doses of rBST had an immune response. Despite numerous media accounts, the study in question has not been forwarded for the scientific scrutiny of peer-review. Was the study scientifically valid? Were the appropriate controls in place? Who knows? The basis of scientific judgment is peer review open for outside scrutiny and repeatability. Otherwise, the electrical needs of Canadians would be met through the wonders of cold fusion. By hiding behind the legalese of commercial confidentiality, Health Canada has allowed critics, including its own scientists, to make what would, according to the majority of the international scientific community, appear to be unfounded accusations. Health Canada could easily issue a statement summarizing the current state of scientific knowledge regarding rBST and the relevant peer-reviewed research. It could make a serious commitment to communicating with Canadians about food-related risk Beyond the angst of genetically engineered dairy hormones, the U..S. Food and Drug Administration has, in the past two months, implemented mandatory labelling for unpasteurized apple cider and warned certain consumers not to eat alfalfa sprouts, in both cases due to the occasional presence of bacterial pathogens which can make people, especially the very young and old, very sick. Similar actions have not been taken by Canadian regulators, although the risk remains, irrespective of geography. Is rBST a risk to human health? Over the years, Health Canada has decided no, then yes, then no, then yes again. The basis for such inconsistency, especially when every major international health authority has agreed that rBST is safe for human consumption, is puzzling at best, political at worst. Allegations about potential human or animal health effects associated with the use of rBST have been circulating for a least a decade, magnified with the advent of the Internet and the World Wide Web. In a democratic society, dissension should not be silenced, but countered with sound science. The promoters of new technologies like rBST have been largely silent, at least in Canada, in responding to challenges about safety. Canadians need a strong, science-based regulatory system. Industry wants and needs a strong regulatory system to augment their claims of safety and efficacy. The alternative has long-term and often undesirable effects. Recently, scientists have identified the emergence of a calcium-deficient generation, as teenagers and others express their lack of confidence by shunning dairy products. Are calcium-fortified indigestion aids really the solution to a crisis of confidence in foods? And will the predicted increase of osteoporosis in the next generation be the legacy of today's bureaucratic stagnation? BEEF COMEBACK October 26, 1998 National Meat Association- Lean Trimmings Jeremy Russell Last year, restaurants served steak 364 million times, up 4% over 1996, reported Restaurants & Institutions magazine on October 1, 1998. But there's another way beef has been getting on menus. Operators across the country are experimenting with smaller portions of beef in various dishes, moving it into a role other than stand-alone star. Examples include ravioli stuffing, rolled beef appetizers and hearty chili. SOUTH AFRICA-ELEPHANTS November 4, 1998 AP PAT REBER BRITS, South Africa -- According to this story, from 1967 to 1995, government rangers killed 14,629 elephants to limit their numbers in Kruger Park. With populations growing at 7 percent a year, Krugerwhich stopped culling to quell international protestis considering reintroduction of the practice later this month to limit its herd of more than 8,000 elephants. UN-SAVING FISH November 4, 1998 AP VANIA GRANDI ROME -- Faced with depleting fish stocks and alarmed by the potential damage to their economies, more than 80 nations have, according to this story, approved a voluntary agreement to limit fishing worldwide. Under the accord, the nations also pledged to protect sharks and seabirds. Each year, thousands of sharks are accidentally caught in nets used by tuna fishermen while thousands of seabirds die when they try to feed off bait on fishing lines and become ensnared by the hooks. This story explained that the agreement was adopted Tuesday at the end of a weeklong conference at the Rome-based Food and Agriculture Organization of the United Nations. It has been submitted to the agency's fishing committee for final approval, expected in February. Serge Garcia, director of FAO's Fisheries Resources Division, was quoted as saying, "In most cases, the greatest risk is not the extinction of fish species but the extinction of economies." U.S. CATTLE GROUP BACKS COMPLAINT AGAINST CANADA Nov 4/98 Reuters CHICAGO - The largest United States cattlemen's group was cited as saying on Wednesday that it would support a trade complaint against Canadian producers but remain neutral on an anti-dumping complaint against Mexican cattle producers. The decision by the National Cattlemen's Beef Association's (NCBA) executive committee, made at a meeting in Phoenix on Tuesday, marked a switch from its neutral position set forth last month on three trade complaints filed with the U.S. government by a private group, the Ranchers-Cattlemen Action Legal Foundation (R-CALF). NCBA President Clark Willingham was quoted as saying, "The face-to-face discussion at NCBA's quarterly executive committee meeting gave us an atmosphere where we could take a more in-depth look at this issue. NCBA has long had concerns about government intervention in Canadian agriculture, particularly from their Wheat Board. There are potential subsidies that can make grain cheaper for cattle producers in Canada, and we need to take a hard look at that. U.S. cattlemen have developed a strong and vital two-way trading relationship with Mexican cattlemen, and it is especially critical that this trade be continued while U.S. cattlemen face poor market conditions." Canadian prairie farmers only can sell wheat and barley for export to the Canadian Wheat Board, a state trading body. NCBA was cited as saying that this keeps the Canadian feed supply artificially high by spreading out payments at a flat price and deducting transportation costs. Many local Canadian farmers sell to local feedlots at market value, which at times gives Canadian feedlot operators a competitive advantage in feed costs. The latest move by NCBA comes after it arranged a "summit" meeting of U.S. and Canadian cattle industry leaders and government officials on October 19 in Denver. WSJ-MEXICAN CATTLE Nov. 4/98 Dow Jones By Joel Millman and Robert S. Greenberger Staff Reporter of The Wall Street Journal MONTERREY, Mexico -- In a related story, U.S. exports of meat products to Mexico have, according to this story, soared since the 1994 passage of the North American Free Trade Agreement, or Nafta, which all but eliminated import duties on them. Beef imports from the U.S. have increased more than 200% since 1993, while pork imports have gone up nearly 40% over the same period. Mexican meat producers have successfully lobbied Mexican authorities to open an investigation into alleged dumping by their U.S. counterparts.
