Feasibility Study for Concrete Swine Buildings and Manure Storage Facilities in Western Canada
Most swine facilities in the Prairies are constructed with wood framing and earthen manure storage facilities. Concrete walls may increase the buildings longevity and rodent control. Concrete manure tanks and walls decrease the production facilities annual costs and increases longevity....
Manure Management in Zero Till Systems
A broader range of nutrients can be provided with manure fertilizer compared to inorganic products. In order to properly use manure, nutrient and soil analyses are needed. Nutrient take time to be released after application of manure; in cattle, they...
Airborne Dust, Endotoxin and DNA Downwind from Swine Barns: An Update
Dust exhausted from swine barns may have endotoxins and microbial DNA present which is an environmental and health concern. Endotoxin is a pulmonary irritant which can cause phlegm, cough, wheezing, fever and in some cases chronic airway inflammation. Microbial DNA...
Dietary Protein and Fermentable Fiber Affect Nitrogen Excretion
Potential environmental impacts both inside and outside the barn can be due to nitrogen excretion. Land base needed to apply manure may be reduced with lower total nitrogen excretion. Reducing dietary protein can reduce ammonia emissions and nitrogen excretion directly....
Dietary Particle Size and Nutrient Supply Affect Nitrogen Excretion
The sustainability of the pork industry is impacted by nutrient management. Previous research has shown that decreasing particle size decreases fecal nitrogen excretion, but it may increase urinary nitrogen excretion. Particle size and diet formulations were examined to see the...
Effects of Nipple Drinker Height and Flow Rate on Water Wastage in Grower and Finisher Pigs
Water wastage is an unnecessary cost in pig barns. On commercial farms, water wastage is as high as 40-60% compared to previous findings that grower/finisher pigs wasted 25% from nipple drinkers. The difference in these numbers could be due to...
Nutritional Value of Debranned Wheat
A nutritional value should be higher in dehulled or debranned cereal grains as removal of the fibrous hull reduces the fibre content. The nutritional value has not previously been explored. Debranned wheat had a higher DE content than the parent...
Dietary Cereal Affects Intestine Bacteria Numbers in Weaned Pigs
With reduction of antibiotic use, control over intestine health may become more difficult. Around 70% of diets for weaned pigs are composed of cereal grain. The fibre from the cereal may have an impact on bacteria populations in the intestine....
Replacement of Soybean Meal with Canola Meal in Weaned Pig Diets
Canola meal has a fibre content that is three times higher compared to soybean meal which may limit nutrient availability as it limits digestibility. Canola meal was assessed in regard to its nutritional value to see if it could replace...
Effects of Fibre in Cereal Grains on Performance of Weaned Pigs
Voluntary feed intake and nutrient content may impact the variation in nutritional value of feed ingredients. Digestibility and nutrient availability is limited by fibre content and negatively affects using Canadian ingredients to feed the pork industry. Differences were noted between...
Effects of Pelleting, Expanding Plus Pelleting, and Enzyme Supplementation on Barley Diets with Wheat Millrun on DE Content
Grower-Finisher feed costs may be reduced if ingredients with high fibre could be included without affecting performance negatively. Treating diets with enzyme supplementation or processing to include barley and wheat millrun may be beneficial. Without reducing performance, wheat millrun can...
Nutritional Value of High-Oil Oat Groats
High oil oat groats are assumed to have a higher DE content and therefore a higher nutritional value though this has not been explored extensively. Oat groats are known for their palatability and high energy density but the natural variant...
