Researchers at Agriculture Canada's Agassiz, B.C. research station have designed a program to add powdered aluminum sulfate to the manure in poultry barns in an effort to lower the level of ammonia created. Ammonia is suspected of wearing down the health of the birds and increasing the levels of suspended particulates of pollution in the air around areas such as the Fraser Valley, where high densities of poultry farms exist Researchers Tom Scott and Kevin Chipperfield are hoping the project, set to end this month, will show lower production costs can be linked to efficiency. Powdered aluminum sulphate (or alum) is spread on the litters in barns and is absorbed into the waste from the birds. During the study, levels of ammonia will be measured before and after the substance is applied to floors of turkey barns. The research has centred on turkeys since they are more susceptible to ammonia levels because they are housed in barns three times longer than chickens are kept Ammonia problems vary, depending on the design and age of the barns, in addition to the management abilities of the producer. So far similar programs in the U.S. appear to be cost-effective for broiler producers. The project is designed to eventually provide farmers with a product they can purchase and use in their barns, but that may not happen for several years. Chipperfield said increased production should off -set the additional costs involved. Aluminum sulphate comes from bauxite which is mined from the earth in raw form, then treated with sulfuric acid to form sulfate.° —Source: Western Producer BSE could be spreading in Europe According to the May 1 issue of New Scientist magazine, BSE or mad cow disease, could be quietly spreading across Europe because farmers and veterinarians are failing to report sick cows. The magazine quoted officials across the continent as saying ignorance and fear contributed to the spread, and it urged better checks of the disease (bovine spongiform encephalopathy). "Of course we have had (unreported) cases of BSE in Belgium," the magazine quoted Emmanuel Vanopdenbosch of the National Institute for Veterinary Research in Brussels as saying. He said animals with strange symptoms of the central nervous system had been slaughtered and often ended up on supermarket shelves. "Frankly, I am worried," he said. Scientists have suspected that meat from cattle affected with BSE may be linked to a new form of Creutzfeldt-Jakob disease, a normally rare human disease that is the human equivalent of BSE. The European Union banned British exports a year ago to try to limit the disease to the island. In Britain there had been 167,000 cases of BSE reported in the past decade and many cattle or their products had been exported to Europe. New Scientist quoted officials as saying given those imports, the expected number of European cases had not turned up. "They were not reported," said Bram Schreuder, head of BSE research at the Dutch Institute of Animal Science and Health. Since 57,900 British cattle were exported to the rest of Europe for breeding between 1985 and 1990, at least 1,688 of them should have become sick, Schreuder said.° — Source: Reuter News Agency
