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...

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 effectiveness. The antibody levels and...

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 nitrogen cycle. Using this knowledge,...

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 and Westbridge (H4-5O2). The additives...
