New Method to Determine Barley DE is Indicative of Performance
Current measurement of grain DE content prevents voluntary feed intake measurements and does not reflect practical conditions. Unrestricted access to nutrient-adequate diets is a proposed method to investigate the DE content of barley. This may be a new method to...
Micronized and Flaked Wheat in Nursery Diets
Micronization and flaking are processes that increase digestibility in young pigs. This is especially true when regarding early weaned pigs, as endogenous enzymatic secretion is not quite established so micronized grains should be beneficial. These processes lead to faster weight...
Phosphorous Requirement of Grower Pigs
In order to reduce the amount of phosphorous in manure to decrease environmental effects, nutrient management for pigs is crucial. By decreasing the amount of phosphorous in feed to its requirement, the amount of phosphorous excreted is reduced. Phosphorous requirements...
Sow Bodyweight Changes in Gestation
Nutrient requirements and feeding strategies should be defined for the modern high-producing sow to increase herd efficiency. Evaluation of the factorial approach to define energy requirements was completed in pregnant sows. Sows between parity 3 and 5 can have the...
Effect of Amino Acid Intake in Gestation on Sow Performance
Maximized productivity and efficiency can be produced through re-defining amino acid requirements for high-producing sows in gestation. Nutrient requirements should be met but not exceeded. Effect of lysine levels were observed, with total intakes over 10.6 g/d (8.3 g Dlys/d)...
Digestibility of Energy and Amino Acids in High-Oil Corn
Knowing the DE value in feedstuff can help to better formulate new diets. High-oil corn digestibility of amino acids and energy and DE content was characterized then related to chemical characteristics. Using gross energy or oil content, corn DE content...
Effect of Dietary Enzyme on Barley Energy Digestibility
Dietary enzymes can improve nutrient digestibility in barley diets. Reducing DE content differences in barley may be achieved through supplemental enzymes digesting fibrous fractions. An ingredient evaluation should be completed to increase enzyme supplementation benefits. Effect of Dietary Enzyme on...
Dietary Enzyme Improves Nutrient Digestibility of Canola Meal-Diets
Non-starch polysaccharides and fiber limit the nutritional value of cereal grains and canola meal. A dietary enzyme (non-starch polysaccharides-degrading enzymes, ß-glucanase and xylanase) was studied on cannulated weaned pigs, looking at increasing nutrient digestibility. Degrading non-starch polysaccharides through supplemental enzymes...
Poor Immunity from a Strep. suis Autogenous Bacterin
A major cause of death in recently weaned pigs is a bacterial infection Streptococcus suis. There are many strains which makes it difficult to control and vaccinate for. An autogenous bacterin vaccine was created for the strain SX-428 and measured for its...
Nitrogen Dynamics in Manured Saskatchewan Soils
Manure is a nitrogen source for crop growth. To predict its behaviour in the soil, the amounts and forms of nitrogen must be known. The behaviour of the manure nitrogen as a plant nutrient source is influenced by the soil...
Effectiveness of Three Manure Pit Additives
Evaluation of three manure pit additives on their effectiveness in reducing manure strength and solids, odour threshold and gas concentrations above the manure surface, and maintaining micronutrient and nutrient content was completed. The additives investigated were Pit Boss, American BioCatalysts...
Development and Evaluation of a Temperature-Humidity Controller for Livestock Buildings
A TDK relative humidity sensor’s life expectancy and accuracy could be improved by applying a specific protection treatment, allowing humidity control strategies. Evaluation of the modified TDK relative humidity sensor and the temperature and humidity control strategy (THC) was completed....
