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 gain, heavier weights and improved...
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 were determined to be 6.2...
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 DE allowances predicted to maximize...
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) of lysine in gestation not...
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 can be predicted. High-oil corn...
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 Barley Energy Digestibility (full article)...
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 improved ileal digestibility of amino...
Factors that Influence Voluntary Feed Intake
Feed intake varies widely on commercial farms. Variations in feed intake lead to variations in nutrient intake levels which impacts pork production efficiency and productivity. Factors involved include social, environmental and immunological stressors as well as dietary factors. In grower-finisher pigs, DE content of feed...
The Threonine Requirement of the Sow in Lactation
The threonine requirement of a high-producing sow in lactation was determined as threonine is the second limiting amino acid in most swine diets. Tissue breakdown was minimized in sows by having a threonine requirement of 37.3, 40.0 and 38.9 g total threonine/d (28.7, 30.8 and...
Field Pea DE Content and Chemical Characteristics
In Western Canada, field peas are a source of amino acids and energy in swine rations. Specific Canadian field pea samples have not been examined for nutritional value or quality previously. Physical and chemical characteristics were analyzed in relation to DE content in field peas...
