Effects of Fibre in Cereal Grains on Performance of Weaned Pigs

Voluntary feed intake and nutrient content may impact the variation in nutritional value of feed ingredients. Digestibility and nutrient availability is limited by fibre content and negatively affects using Canadian ingredients to feed the pork industry. Differences were noted between...

Effects of Pelleting, Expanding Plus Pelleting, and Enzyme Supplementation on Barley Diets with Wheat Millrun on DE Content

Grower-Finisher feed costs may be reduced if ingredients with high fibre could be included without affecting performance negatively. Treating diets with enzyme supplementation or processing to include barley and wheat millrun may be beneficial. Without reducing performance, wheat millrun can...

Nutritional Value of High-Oil Oat Groats

High oil oat groats are assumed to have a higher DE content and therefore a higher nutritional value though this has not been explored extensively. Oat groats are known for their palatability and high energy density but the natural variant...

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...

Effect of Gender and Crowding on Variation in Days to Market

Variation in the production chain has a large economic impact. Variation of growth due to gender and crowding during the grower-finisher phase were examined. Less crowding reduced days until market by four days. Holding gilts longer than barrows may be...

Thermoregulation of the Nursery by Early Weaned Piglets Through Operant Conditioning

Growing swine health and productivity is affected by thermal environment, especially in newly weaned piglets as they require warmer temperatures. Pigs were taught how to respond to heat rewards through operant conditioning and control their thermal environment so they can...

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...

Mask Use in Swine Barns Reduces Health Effects

Dust and gas exposure is common in swine barns. Workers exposed are at a higher risk of having decreases in lung function levels, developing respiratory symptoms and increases in airway reactions. To reduce exposure, workers should wear a disposable respirator...

Clogging and Flow Reduction in Soil Materials by Ponded Hog Manure

An economically viable option for storing manure is using earthen manure storage. Proper construction and soil materials are crucial to avoid contamination. Soil pores can be clogged by liquid hog manure, though this clogging is a surface effect and can...

Influence of Hog Manure Application on Water Quality and Soil Productivity

Impacts of organic fertilizers on the environment are not known on ecosystems that are semi-arid to sub-humid. Hog manure is a source of nutrients as a fertilizer and more research should be done to understand its impact. The presence and...
