Airborne endotoxin and microbial DNA outside a swine barn

Posted in: Prairie Swine Centre by admin on January 1, 2001 | No Comments

This study was designed to quantify the amount of airborne endotoxins and microbial DNA downwind from a swine facility. There is reason to believe that endotoxins and microbial DNA are present in dust exhausted from swine barns and that adverse health affects may occur from inhalation of this dust. Ambient air samples, dust extractions, endotoxin analysis and microbial DNA analysis of air were taken directly from outlets, 600m downwind and 2400m upwind of the barn. Concentrations of total dust, endotoxin and microbial DNA 600m downwind from the barn were not statistically different from concentrations 2400m upwind where the air was considered to be a

Effect of group size on aggression of grower-finisher pigs

Posted in: Prairie Swine Centre by admin on | No Comments

Research on management and performance of grower-finisher pigs has generally been conducted with small group sizes, while the swine industry has shifted towards larger group sizes. Our previous study shows that productivity of pigs was not affected by group size up to 80 pigs/pen. However, there are still concerns about aggression and injuries among pigs in a large group. The objective of this study was to determine effects of group size on aggression and injuries of pigs.

Response to dietary energy concentration and stocking density in weaned pigs

Posted in: Prairie Swine Centre by admin on | No Comments

Understanding the effect of energy intake on growth performance and body composition of pigs is critical for the development of economical feeding strategies. However, Knowledge is limited on the influence of varying amounts of DE content on growth and body composition according to the growth potential of the pig. A study was conducted to examine the effect of increasing dietary digestible (DE) concentration on weaned pig performance at the farm level. Results indicate that higher dietary DE concentration may not improve weaned pig performance.
