The Effect of Ergot on the Performance of Weanling Pigs
Ergot reduces the quality of grain as a number of poisonous alkaloid-containing ergot sclerotia have replaced grain kernels. If these grains end up in the feedstuff of swine it may impair development and growth and decrease hormone concentrations like prolactin....
Feeding Level Affects Barley DE Measurements in Grower Pigs
Nutrient content and feeding level of diets used in DE content measurement for grains prevent voluntary feed intake measurements and practical conditions are not reflected. Three barley samples with different fibre content were studied to look for differences in voluntary...
Response to Dietary Energy Concentration and Stocking Density in Weaned Pigs
The primary limitation to growth in the young pig is assumed to be the gut capacity since it limits their daily energy intake. Increasing the dietary DE concentration seems to be an effective way to overcome this issue, but by...
The Impact of Feeder Adjustment and Group Size/Density on Weanling Pig Performance
Nursery performance is negatively affected when crowding or reduced floor space increases ear chewing, tail-biting and side-nudging. Crowing often leads to decreased feed intake. Feeder adjustment may work synergistically with adequate floor space to improve pig performance. Reduced crowding is...
Particle Size Reduction and Enzyme Supplementation Reduce Nutrient Excretion
Long-term sustainability of the swine industry is impacted by nutrient management. In order to reduce the nutrients phosphorous and nitrogen being produced at operations, some strategies that can be used are particle size reduction and enzyme supplementation. To reduce phosphorous...
Oil Sprinkling and Dietary Manipulation to Reduce Odour Control and Gas Emissions from Grower-Finisher Buildings – Laboratory Scale Experiment
Hog barns emit a continuous emission of odours by the ventilation system which have a negative impact on the surrounding area. Canola oil sprinkling and specific pig diets may be able to decrease the gas and odour emissions from swine...
Dietary Factors Influencing Water Consumption
Water is required in greater amounts than any nutrient and is necessary to biological functioning. Reducing water consumption and wastage will help reduce some environmental concerns such as pollution and groundwater stores and decrease costs of storing, spreading and hauling...
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)...
