Temperament Traits Related to Stress and Meat Quality: Are they Reliable and Heritable?
Welfare, ease of handling, stockperson labour required to move and productivity are all influenced by the susceptibility of pigs to stress. Severe losses for packers and producers often arise from stress during transport and handling of pigs at marketing. This includes in-transit death losses, reduced...
Development of an Air Filtration System for Swine Transport Vehicles to Protect Against Airborne Diseases During Transport
Transporting breeding stock across Canada is a daily occurrence with farms each having biosecurity procedures to reduce potential disease outbreaks. Infecting breeding stock during transport is a risk, especially through pig dense areas. Measures are needed to protect breeding stock during transport to avoid infection...
Benchmarking and Standardization of Swine Production Systems
Wide variations in building design, barn equipment, construction, management and other operational systems contribute to added costs and inefficiencies in hog barns. These variabilities make it difficult to develop improvement measures and they cannot be applied from barn to barn as they are all so...
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...
Effects of Transport Duration on the Stress Response and Pork Quality of Pigs
Transporting pigs in Canada has many challenges. These include extremes of temperature and long transport durations that can cause stress in pigs, affecting welfare, transit losses and meat quality. Transport times of 6, 12 and 18 hours were studied on meat quality and stress physiology,...
Loading Facilities for Market Hogs: Saskatchewan’s Top 10
Loading facilities can result in longer loading times, increased incidence of rough handling and prod use if poorly designed. Stress associated with this can affect meat quality, carcass and also increase the amount of downer pigs and losses. Ten Saskatchewan barns were observed to see...
Assessment of Lameness, Productivity and Longevity in Group and Individually Housed Gestating Sows
There may be several major welfare issues in facility design and sow management for group sow housing. One of the most important welfare issues is lameness. It is the second major cause of culling after reproductive failure. visual scores can be used to measure lameness...
Impact of Repeated Applications of Liquid Swine Manure and Biogas Production By-Products on Soils and Crops
Different methods of swine manure use are of interest Crop response to swine manure biodigestate produced by biogas production compared to the conventional liquid swine manure and urea fertilizer was looked at. Applying long and short-term fresh and processed liquid swine manure to Saskatchewan soils...
