    Heat stress can decrease farrowing rates and depress litter size for sows and gilts. Heat-stressed sows may also produce less milk, resulting in smaller piglets at weaning. Attempts to modify farrowing room environment to reduce heat stress commonly center on reducing the internal body temperature of the sow during periods of high ambient temperatures...More

    2011 Swine Research Review - Manure Management

    Traditional gas-phase biofilters successfully reduce odor and gas emissions from swine buildings. The most common type of biofilter media is wood chips. The problem with wood chips is that they degrade easily and cause compaction over time. This results in a pressure drop in the building that mechanical ventilation systems and pit fans must overcome...More

    2011 Swine Research Review - Nutrition

    In a trial at the Prairie Swine Centre, pigs were subjected to an immune challenge by injecting lipopolysaccharide (LPS), a component of gram-negative bacteria that triggers an immune response. As a result, weaned pigs produced from sows consuming different fatty acid ratios responded differently to an LPS-induced immune challenge. Researchers concluded that the fatty acid profile of a sow’s diet may affect the response of her offspring to immune challenges that regularly occur at weaning...More
