Loading Facilities for Market Hogs

Author(s): H. Gonyou, J. Brown Publication Date: April 18, 2012 Reference: Centred on Swine 17-2 Country: Canada   Summary: For swine producers, loading pigs at marketing can be one of the most stressful and time-consuming experiences. Problems at loading also affect the welfare of animals and have a significant economic impact as they may cause

Water Availability and Crowding

Space allowance, or stocking density, is expressed in terms of pigs per floor area. Space allowance requirements are based on the body weight of the pig, which is proportional to surface area of the pig. The optimal space allowance is the minimum area per pig for maximal individual weight gain. Many experiments have arrived at the same conclusion: “a decrease

Can sow diets enriched with extruded flaxseed replace antibiotics in starter feeds for piglets?

Authors: L. Eastwood, D. A. Gillis, M. R. Deibert and A. D. Beaulieu Reference: Western Hog Journal Fall 2015 This study aims to test whether the addition of omega-3 fatty acids into lactating sow diets can replace the use of growth promoting antibiotics in weaned piglet diets. Two groups of sows (one weaned at three weeks

Dietary ω-6 to ω-3 Fatty Acid Ratios Affect Protein Deposition in Nursery Pigs

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

Ecopiglet from Olmix

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

The Importance of Nitrogen for Growth

After energy, protein is the second most expensive nutrient in swine rations but utilization tends to be low.  Retention of dietary nitrogen in pigs ranges from 30% to 60% of intake with much of this inefficiency the result of catabolism of excess amino acid/protein intake or unbalanced amino acid supply.  This catabolism represents an energetic

Marine algae to reduce the use of antibiotics in farming

As part of a partnership with Olmix Group, Inra researchers have shown that a compound extracted from green algae inhibited the growth of pathogenic bacteria in vitro and stimulated the production of immunity mediators by intestinal epithelial cells. This type of preparation could be used in livestock feed to improve animals’ resistance to infections and

Replacement of Acid Components in Pig Diets

For nutritionists, there is sometimes when they are very stressed because the space in the feed is somehow limited: it always has to add up to 100%. They would like to have 110% because they want to add more vitamins, more premix, etc. There’s always a question: is there a way to make room in

What is MSP[RS]® Resistant Starch?

MSP is a resistant starch (RS) that is highly fermentable by microbiota in the colon of swine.  RS has proven to mediate a large proportion of its growth and health benefits through actions of short chain fatty acid (SCFA) production.  MSP acts as an effective prebiotic and its absorbent properties will help ensure against bacteria,

Determining the optimal sampling method to estimate the mean and standard deviation of pig body weights within a population

Paulk, Chad B.; Tokach, Michael D.; Dritz, Steven S.; Nelssen, Jim L.; DeRouchey, Joel M.; Goodband, Robert D. The accuracy and precision of pig subsampling methods can determine the swineproducer’s ability to sell pigs at optimal market BW and reduce economic discounts. The first objective of this experiment was to determine the time required to
