Authors: Laura Eastwood and Denise Beaulieu Reference: Prairie Swine Centre Annual Research Report 2013-14 An experiment was conducted to determine if decreasing the dietary omega-6 (ω-6) to omega-3 (ω-3) fatty acid (FA) ratio would affect protein deposition in nursery pigs during a prolonged E. coli lipopolysaccharide (LPS) inflammatory challenge. Following a one week long challenge, six week old piglets
Biosecurity – Bio-Management Joe Rogowsky DVM When someone mentions biosecurity, the first thought that comes to mind is preventing the entry of a new pathogen or “bio-exclusion.” However, biosecurity also includes managing the pathogens already on the farm or “bio-management,” and here are some thoughts on that topic. When sorting out a health
New research from the University of Illinois shows that adding supplemental dietary fat is not necessary to avoid reduced growth performance when replacing soybean meal with canola meal in diets fed to weanling pigs. Canola meal contains more protein than most plant ingredients, and can be used in place of soybean meal in pig diets.
Canadian pork production has made a tremendous transition from smaller family farms into large-scale high-production barns. This transition has spurred several process changes and technological advancements throughout the Pork Value Chain. So let’s say you are presented with a new technology, tool, or method to help production. How do you decide if it is going
Michigan State University research and extension teams focus on pig aggression – Part 2 to the nature of pig production systems, pigs may have to be re-grouped at various stages, for example, entering the nursery stage, the feeder/finisher stage, at transport and/or immediately before slaughter. Vigorous fighting associated with re-grouping events can cause injury, stress,
Nick Boddicker, Ph.D. Genomics has become commonplace for any serious swine genetics company and it is used to improve genetic gain, which directly affects profitability for the customer. Genotype information is the foundation of genomics and genomic selection. Genotyping is carried out using special “chips” that read predetermined markers or single nucleotide polymorphisms (SNPs).
Hog producers understand the importance of ‘hitting the ground running’ when it comes to raising pigs, especially those working in the farrowing unit. Day one pig care is a hot topic, and is constantly being adjusted and improved upon. But what about the remaining ~20 days in the farrowing unit? With such a naïve immune
Why pig aggression? Despite undergoing genetic selection for commercial production, free-ranging (feral) pig populations adopt similar behavior to their wild boar ancestors, living in social groups of two to six females along with their litters, and sub-adults . These groups form linear dominance hierarchies, based on age and size, with one “boss sow” and the
Work at Prairie Swine Centre indicates that sows in group housing systems will maintain room temperatures between 9 to12 0C, leading to approximately 78% reduction in energy consumption when compared to gestation rooms maintained at pre-set temperature of 16.50C. Conversion of gestation sow housing from stalls to group systems has been mandated in the recently
Dietary fiber is resistant to digestion in the small intestine, but is fermented in the large intestine and the resulting short chain fatty acids provide some energy to the pig. Fermentation occurs to a greater or lesser degree depending on the chemical and physical composition of the fiber; soluble fiber is generally fermented to a
