Evaluation of Heat Exchanger, Ground Source Heat Pump, and Conventional Heating Systems
A production cost that can be further reduced is energy cost. This can be done by reducing overall energy consumption or using energy more efficiently. Space heating is an area of interest for energy reduction. The performance of a heat recovery ventilator, a conventional heating...
Using Zinc Oxide Nanoparticles to Control Emissions – Pig Performance, Manure Properties, and Production Cost
Filtration and mixing methods using zinc oxide nanoparticles were effective in controlling odour, ammonia and hydrogen sulphide emissions from swine facilities. This is important to the health and safety of the workers and the environment as well. The feasibility of these methods in commercial swine...
Development of Diets for Low Birth-Weight Piglets to Improve Post-Weaning Growth Performance and Optimize Net Returns to the Producer
A cost to the commercial pork production is variability in growth. Birth weights have a large variance from 0.40 kg to 2.5 kg. The smaller pigs rarely demonstrate compensatory growth and have a lagging rate of gain throughout all growth stages, often needing an additional...
Weaning at 28 Days. Is Creep Feeding Beneficial?
Creep feeding in the farrowing room is often practiced to ensure the transition to solid feed at weaning goes smoothly. This is important as weight loss and increased disease risk are often noted post-weaning due to the stressful transition. Even a limited amount of creep...
Do Peas and Canola Meal have Synergistic Effects when Included in Diets for Growing Pigs?
Canola meal may mask the taste of a field pea diet that has been hypothesized to impact palatability. These two ingredients are often used in diets together as they are produced in Western Canada and have complementary amino acid profiles for their proteins. The interaction...
Effects of Altering the Omega-6 to Omega-3 Fatty Acid Ratio in Sow Diets on the Immune Responses of their Offspring Post-Weaning
Feed intakes are reduced and immune responses are generated at weaning as it is the most stressful time in a piglet's life. Since omega-3 fatty acids have anti-inflammatory properties, they could improve performance post-weaning by altering their immune status. The omega-6:omega-3 ratio given in sow...
Dietary Omega-6 to Omega-3 Fatty Acid Ratios Affect Sow Reproduction and Piglet Performance
Maximizing the reproductive performance of sows is crucial to optimize pig flow and improve the economics of the production of pork. Many nutritional strategies have been used and there is growing interest in using dietary polyunsaturated fatty acids like the omega-3 fatty acids alpha-linolenic acid...
Dietary Omega-6 to Omega-3 Fatty Acid Ratios Affect Colostrum, Sow and Piglet Plasma Fatty Acid Profiles
Omega-3 polyunsaturated fatty acids (PUFA) have proven health benefits, such as anti-inflammatory properties. Omega-6 PUFA's have the opposite biological activity and since direct competition occurs between them, the ratio is important to maximize the benefits of including omega-3 fatty acids in sow diets. Plant sources...
Literature Review and Needs Assessment of Housing Systems for Gestating Sows in Group Pens with Individual Feeding
Group housing is a complex system, but it is one that the society is moving towards. There are many options in regard to choosing group housing for gestating sows. The housing systems from lowest to highest welfare are: tethers and stalls, indoor group housing then...
Effects of Temperament and Floor Space Allowance on Sows at Grouping
Producers are changing their facilities to group housing for sows. Spacious accommodation has been shown to reduce aggression and increase general health but the point of crowding is not known. Observations were made in order to configure space requirements and social groups. More space was...
