Effects of Altering the Omega-6 to Omega-3 Fatty Acid Ratio in Starter Diets on Piglet Inflammatory Response
Many new stressors are present at weaning, including immune challenges. These stressors can result in an inflammatory response as well as reduced feed intake and growth. An over-production of immune cells can result in increased muscle degradation and reduced protein synthesis. Omega-3 fatty acids have...
Spray-Dried Animal Plasma Mitigates the Negative Impact of Deoxynivalenol (DON) in Nursery Pigs
There is an increase in prevalence of deoxynivalenol (DON) contaminated grains in the Canadian Prairies. DON is the toxin produced by Fusarium fungi, which is affected by the moisture content during flowering and/or harvest. Grains that are contaminated with DON are either destroyed or fed...
Determining the NE Content of Diets and Ingredients
Feed has a large impact on the efficiency of production. Over 65% of the total hog production cost is due to feed. Energy is the most expensive component at 90%, so characterizing the available energy in a feed is required to estimate its overall feeding...
Creep Feed Provision in the Farrowing Room Provides Benefits to Piglets Showing Evidence of Intake
By supplying feed in farrowing (creep feed), the piglets should benefit by being introduced to solid feed, having supplemental nutrition and by helping the gastrointestinal tract adapt to new proteins and nutrients. Some studies have found that no benefits were noted when piglets were provided...
Dietary Omega-6 to Omega-3 Fatty Acid Ratios Affect Body Fat Mobilization During Lactation
Litter sizes have increased due to improved management practices and genetics, though pre-weaning mortality is even higher now. This may be due to sows not being able to keep up with the energy demands of the litter. Over subsequent parities, loss of body condition and...
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...
