Evaluating Transport Conditions on Weaned and Feeder Pig Performance

Weaned Pigs Require More Care in Transport Researcher: Dr. Jay Harmon, Iowa State University In this project, researchers reviewed data from more than 7,000 loads of weaned and feeder pigs, looking for possible mortality relationships and the long-term impact of transport stress on piglets and the environmental characteristics within the trailer. Researchers found that weaned […]

Cold Pelleting Can Maximize Feed Efficiency, Nutrients and Economic Return

May Improve Nursery Pig Performance Researcher: Dr. Charles Stark, Kansas State University Pork producers continue to grind feed to very fine particle sizes, resulting in diets with high levels of fine powder. The fine particles (less than 150 microns) create problems during feed manufacturing and delivery, as well as on-farm feeder management. While removing fine […]

January/February 2015 Pork Checkoff Research Review

Evaluating Feed Processing of Wheat in Swine Diets The point was to expand knowledge of how particle size and pelleting for nursery and finisher diets containing wheat can improve performance and economic return. Key Points: Feed efficiency improves as wheat particle size drops to less than 600 microns for meal diets, but not for pelleted. […]

March/April 2015 Pork Checkoff Research Review

Effects of PRRS Challenge on Pig Growth and Metabolic Pathways The goal was to characterize changes in blood metabolic and immunological parameters of pigs infected with PRRSV. Seventy-six gilts were selected and randomly assigned to one of four pens in a commercial finishing unit. Key Points: Within a population, pigs handle a porcine reproductive and […]

May/June 2015 Pork Checkoff Research Review

Analysis of Swine Manure Application Practices in the Midwest The goal was to identify available and feasible on-farm best management practices and technologies for swine manure storage and land application. Key Points: As animal production concentrates, increased manure nutrients and could reach levels requiring export to maintain land nutrient balance. Manure separation technologies are more […]

July/August 2015 Pork Checkoff Research Review

Impact of Disease on Growing Pigs’ Amino Acid Requirements A total of 40 gilts were used in three experiments to evaluate the impact of disease induced by bacterial lipopolysaccharide (LPS) or PRRSV on immune function measures, as well as protein and AA utilization. In trial 1, AID and protein retention were determined in saline-treated pigs. […]

September/October 2015 Pork Checkoff Research Review

Improving the Welfare of Group-housed Sows Fed via Electronic Feeding This study was designed to examine different ways of mixing sows into a large, dynamic pen equipped with electronic sow feeders. Aggression was minimal immediately following sow introduction, and different strategies for mixing sows did not affect the study’s outcomes. Key Points: Increased weight loss, […]

November/December 2015 Pork Checkoff Research Review

A Physiological Test for Sow Longevity The objective was to determine whether vulva reddening and swelling in response to low levels of gonadotropins given to gilts at an early age could provide a screening tool to estimate potential longevity. Key Points: Farrowing rates and pigs born alive were similar between gilts responding to PG600 and […]

January/February 2016 Pork Checkoff Research Review

Evaluation of an in vitro digestibility procedure for dietary fiber in high-fiber feed ingredients fed to growing pigs The objective was to develop and validate a nutritional tool to measure in vitro digestibility of fiber among high-fiber ingredients. Also to measure changes in gut physiology and function of growing pigs fed diets with different fiber […]

March/April 2016 Pork Checkoff Research Review

Microbially Converted Soybean Meal as Fishmeal Substitute in Nursery Diets This study evaluated the nutrient digestibility of microbially converted soybean meal (MCSBM) and its suitability as a fishmeal replacement in early weaned pig diets. Thirty-seven pigs were used to determine the crude protein and amino acids digestibility of MCSBM and fishmeal. Key Points: Microbially converted soybean […]
