Management Practices to Reduce Greenhouse Gas Emissions from Swine Production Systems
Posted in: Environment by admin on January 1, 2003 | No Comments
Total greenhouse gas emissions from swine production systems in Canada are equal to about 3% of the total agricultural emissions (which is equal to 0.006% of the total world greenhouse gas emissions!). Today there are a number of technological and management options for reducing greenhouse gas emissions associated with manure management within those systems. However, it is important that greenhouse gas mitigation in pork production systems be addressed from an integrated aspect that that involves other agronomic, economic, environmental, health and safety, social and technical considerations. In addition to greenhouse gas emission reduction, another important issue that will need to be addressed in the short term is the adaptation of Canadian pork production systems to climate change in terms of availability of feed materials and water and on the design and management of production facilities.

The influence of zoonotic pathogens in animal manure on human health and well-being as a direct or indirect cause of human enteric illness is examined. Available international data are considered, but the study is focused on the developing situation in western Canada, where it is certain there will be further rapid growth in livestock numbers, particularly hogs. Major pathogens considered are Escherichia coli O157:H7, Salmonella, Campylobacter, Yersinia, Cryptosporidium, and Giardia. Canada is now the leading exporter of pork internationally, but recent increases in production contrast with constant domestic levels of pork consumption and declining levels of foodborne illness caused by pork. Effects of increased levels of manure production are not quantifiable in terms of effects on human health. The presence of major pathogens in manure and movement to human food sources and water are considered on the basis of available data. Survival of the organisms in soil, manure, and water indicate significant variability in resistance to environmental challenge that are characteristic of the organisms themselves. Generally, pathogens survived longer in environmental samples at cool temperatures but differences were seen in liquid and solid manure. Based on actual data plus some data extrapolated from cattle, manure environments, holding manure at 25degreeC for 90 d will render it free from the pathogens considered above.
