Soluble and Insoluble Non-Starch Polysaccharides on Digesta Passage Rate and Voluntary Feed Intake of Grower Pigs
Economically, supplementing or substituting alternative non-conventional feed ingredients to conventional feed ingredients in pig rations may be attractive, but feed utilization and voluntary feed intake may be compromised due to non-starch polysaccharide (NSP) fractions. These are not digestible and may...
The Effect of Starter Feeding Regimen on Variability in Bodyweight and Performance in the Nursery
Negative impacts on revenues and expenditures are associated with variability in performance and growth. Variation either needs to be managed or reduced. Starter program effects may influence the growth of individual pigs in the nursery to allow younger or smaller...
Impact of Combining a Low Protein Diet and Oil Sprinkling on Odour and Dust Emissions of Swine Barns
Oil sprinkling has been shown to be an effective dust control strategy. It also reduces gas emissions which may effect the odours emitted from the barn. To further investigate this area, protein diet with fermentable carbohydrates were included to see...
A Low Protein Diet and Oil Sprinkling to Reduce Ammonia Emissions from Pig Barns
Ammonia concentrations have adverse effects on the environment and the health of workers and animals. Reducing dietary protein and using fermentable carbohydrates in diets previously resulted in reduction of ammonia emissions. Oil sprinkling may also have an impact on ammonia...
Effect of Dietary Crude Protein Content and Phase Feeding on Performance and Urinary Nitrogen Excretion of Grower Pigs
Urinary nitrogen is emitted as volatile ammonia which impacts the environment inside and outside the barn. A way to directly reduce urinary nitrogen excretion is by reducing dietary protein while still balancing for amino acids. Phase feeding may also be...
Can We Alter Water Utilization in Growing Pigs by Diet Manipulation?
Precisely defining the water needs of pigs is of interest as concerns regarding water use of livestock increase along with manure management having rising costs. Diet consumption may impact voluntary water intake in swine. Increased water intake was noted when...
The Net Energy System and Diet Formulation: An Overview
Ingested feed breakdown produces available energy which is often reduced as heat or used for metabolic processes. 50 to 60% of the total energy in common feed ingredients is available for use by the pig. Digestible energy (DE) is not...
The Methionine Requirement of Pigs from 25 to 50 kg
Dietary balance is crucial in swine operations in order to ensure pig performance is optimal. In most commercial swine diets, methionine is not a limiting amino acid so there have been less studies completed on it. In Canadian diets, protein...
The Performance of Growing-Finishing Pigs Fed Diets with Reduced Crude Protein
To reduce greenhouse gas emissions by lowering nitrogen output in the slurry, formulating practical diets is more flexible in regard to low protein diets. In the past, lower crude protein was associated with fatter carcasses and reduced growth performance. Pigs...
The Effect of Dietary Energy Concentration and Lysine: Energy Ratio on the Growth Performance of Weaned Pigs
Expected pig performance has been increased with improvements in lean growth potential and health status so reevaluation on amino acid requirements is needed. Specifically on the lysine requirement and the ratio of DE to lysine for weaned pigs. Current ratios...
Water Usage by Grower-Finisher Pigs Using Dry and Wet/Dry Feeders
For environmental and financial reasons, water conservation is a concern for intensive swine operations. Wet/dry feeders may provide potential water savings by replacing dry feeders. Water usage of both feeders was recorded for grower-finisher swine. Wet/dry feeders reduced volume of...
Feed Processing and Nutritional Quality Among Wheat Classes Fed to Weaned Pigs
Wheat processing and nutritional quality varies among classes such as CPS, durum and High Red Spring wheat. Nutritional quality versus wheat class was examined for their effect on feed processing. Weaned pigs performance was compared across six wheat classes with...
