Reducing Odour and Noise Conflicts Between Rural Neighbours

Posted in: Environment by admin on January 1, 1997 | No Comments

General informations and guidelines are given to reduce and deal with conflicts between rural neighbours considering that the rural population often does not have a direct link to agriculture anymore. Those problems can be odour or noise related. Five SMART methods (Separation, Magnitude reduction, Alteration, Reduction and Timing) are presented to reduce possible odour and noise conflicts. The necessary methods to solve complaints problems are also presented and they are : hearing both sides of the complaint; developing an abatement program; and follow up.

Social Consequences of Environmental Concerns (1)

Posted in: Environment by admin on | No Comments

The changes in the pork industry with the decline of the number of small producers and the increase number of large scale production units bring concerns about family farming and life quality in rural communities and neighborhoods. Opposition to the expansion of large intensive production units comes mainly from concerns about the environment and the impact on neighborhoods. Controversy comes from the values and belief that have either pork production advocates or critics. Often what is considered by one group as a fact may be judged by the other as a myth. Facts and data, when they exist are often not acceptable to all parties. One factor that can be pointed to explain environmental problems seems to be poor management practices and poor managers. And this is not related to the size of the swine farm or production unit. Large production units well manage may have much less environmental impacts than smaller units where balance between livestock numbers and available land is inappropriate, or if manure is considered as a waste. As changes in the society occur and pork producers become a more of minority even in areas where the number had been once important, it is unreasonable to expect that farming could benefit from exceptions or privileges when environment is considered. Environment has to become an important concern of the pork industry as environmental record is often seen as a good indicator of community commitment. Industry with bad environmental record are often viewed as unwelcome development and become the target of more public scrutiny and regulation.

The elements brought in this article are very interesting in the way they present the situation and the fact that the swine industry advocates and the critics don’t have the same view of the production and don’t see things from the same grounds. However no path of solutions are given. The management seem to be the key toward better respect of the environmenta

Attack of Concrete Floors in Pig Houses by Feed Acids: Influence of Fly Ash Addition and Cement-bound Surface Layers

Posted in: Environment by admin on | No Comments

Concrete AYoors in pig houses are subject to attack by lactic and acetic acid, formed in spilled and soured mealA?water mixtures. Accelerated degradation tests, comprising cyclical exposure to acidic liquids and detachment of the unstable concrete by brushing, were used to simulate the attack of concrete AYoors and of cementbound surface layers. It is estimated that the eA

Injecting liquid hog manure for improving crop yields

Posted in: Prairie Swine Centre by admin on | No Comments

The application of hog manure resulted in significant increases in soil fertility, soil structure and crop production; and when applied at a rate of 8,000 gallons per acre , these effects lasted into the second year. The inclusion of elemental sulphur resulted in the greatest increase in crop production on a sulphur-deficient soil at Star City. However, at the other sites the sulphur appeared to decrease the effectiveness of the hog manure. Our research indicates that the acidification process of S-mineralization may negatively affect N-mineralization.

Book Review: ‘PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME (PRRS)’

Posted in: Air Filtration, Pork Insight Articles by admin on August 31, 1996 | No Comments

This is a short review of the book Porcine Reproductive and Respiratory Syndrome (PRRS). When PRRS was first discovered it caused a large amount of concern and even more when it was found in Germany in 1990. Since then a lot has been learned about the virus that is responsible for the disease and it is recognized as a disease to be lived with rather than eliminated. Fortunately the disease was not as severe for most farms as originally feared. This does not take away from the importance of the work being done to understand the disease. The author of the review believes it is an important book for swine veterinarians.
