Evaluation of Methods for Controlling and Monitoring Occupational Exposure of Workers in Swine Facilities
Different management and engineering measures can control the levels of air contaminants like dust and ammonia in swine facilities. This helps lower the safety risk of workers in the barn. Control measures were assessed on their effectiveness on decreasing respirable dust and ammonia levels. Low...
Comparative Evaluation of the Use of Heat Exchanger, Ground Source Heat Pump and Conventional Heating Systems in Grow-Finish Rooms
Profitability of swine production will be improved with any measure that reduces production cost. Using energy efficiently will help reduce the cost of energy. This can be done in the area of space heating. Energy consumption, in barn environment and animal productivity were observed when...
Controlling Environmental Emissions from Swine Barns using Zinc Oxide Nanoparticles
A long-term concern to humans, animals and the environment are the environmental emissions produced by hog production operations. Previous work investigated nanoparticles and their ability to control hydrogen sulphide, ammonia and odour emissions from swine manure. Zinc oxide nanoparticles had the greatest potential for doing...
The Effect of Different Feed Ingredients on Fermentation Metabolites and Nitrogen Excretion in Pigs
Protein and dietary fibre fermentation in the pig intestine may have harmful or beneficial effects on gut health and the environment. Fermentable fibres can be a source of energy for the pig and can also decrease ammonia concentration in the gut. Including fermentable fibre in...
In Vitro Fibre Fermentation Characteristics of Specialty Ingredients with Varying Non-Starch Polysaccharides Levels
New alternative feed ingredients with functional properties to improve gut health while having a positive impact on the environment are wanted in the pork industry. Fermenting dietary fibre in the intestine results in short-chain fatty acids forming which stimulate growth of beneficial bacteria and limits...
Effect of an NSP-Hydrolysing Enzyme (Rovabio Excel®) in the Diet of Lactating Sows on Feed Intake, Body Condition and Litter Performance and In Vivo and In Vitro Nutrient Digestibility
The main ingredients in cereal grains are protein and starch. These nutrients are surrounded by non-starch polysaccharides (NSP) which are indigestible carbohydrates. To release the nutrients, the cell wall must be broken down, but this is difficult as some are soluble in water resulting in...
Enriching Pork Products with Omega-3 Fatty Acids May Affect Pork Quality
Consuming omega-3 fatty acids has benefits to human health. When a pig consumes fatty acids, they are deposited in the pork fat. This is true when consuming flaxseed or flaxseed oil which enriches the carcass in omega-3 fatty acids. Co-extruding the flaxseed with peas, such...
The Effect on Growing Pig Performance of Changes in Energy Intake Achieved Through Restriction of Feed Intake Versus Changes in Dietary Energy Concentration
Altering the energy density of the diet or restricting feed intake can manipulate the pig's energy. These changes in energy intake were monitored to see the pig's response. Dietary energy changes may not change the energy intake of the pig, but restriction of feed does....
Impact of Feeding Diets Containing Extruded Flaxseed Meal and Vitamin E in Finishing Swine
Other pork attributes should not be reduced when enriching pork with omega-3 fatty acids. Eating omega-3 enriched pork can have health benefits when consumed so it is desirable to produce. Feeding flaxseed enriches the omega-3 content of the pork, especially in high fat products. Previously,...
Effects of Transport Conditions and Vehicle Design on the Welfare and Meat Quality of Pigs in Western and Eastern Canada
Transport conditions can have an impact on the economics of pork production and on animal welfare. Swine transportation in Canada is highly variable in the aspects of seasonal changes, distance of transport and types of vehicles used. Differences in truck compartments, truck types and seasons...
