Restraint Of Livestock

Temple Grandin Assistant Professor Department of Animal Sciences Colorado State University. During twenty years of work on livestock handling and design of restraining devices for animals I have observed that many people attempt to restrain animals with sheer force instead of using behavioral principles. Improvements in the design of restraining devices enhances animal welfare and

Tiny bubbles help heal broken bones, in pigs

Source:American Association for the Advancement of Science Summary:Researchers have developed a much needed alternative to bone grafts that could help alleviate the long-term hospitalization, disability, and considerable costs to the health system associated with non-healing fractures. Researchers have developed a much needed alternative to bone grafts that could help alleviate the long-term hospitalization, disability, and

Two clinical isolates of Mycoplasma hyosynoviae showed differing pattern of lameness and pathogen detection in experimentally challenged pigs

Citation J Vet Sci 2016, 17(4), 489-496 Comments ⓒ 2016 The Korean Society of Veterinary Science. Abstract Mycoplasma (M.) hyosynoviae is known to colonize and cause disease in growing-finishing pigs. In this study, two clinical isolates of M. hyosynoviae were compared by inoculating cesarean-derived colostrum-deprived and specific-pathogen-free growing pigs. After intranasal or intravenous inoculation, the

Weaning Sows Directly into Group Housing: Aggression, Welfare & Production

Social stress from mixing sows has the potential to negatively affect sow production and welfare. Housing sows in stalls from weaning until five weeks after breeding is a common strategy used to prevent aggression and ensure control over individual feeding during breeding, conception and implantation.   However, alternative management options are needed as pressure to reduce

Michigan State University research and extension teams focus on pig aggression – Part 1

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

Genetic and Genomic Basis of Antibody Response to Porcine Reproductive and Respiratory Syndrome (PRRS) in Gilts and Sows

  Our recent research showed that antibody response to porcine reproductive and respiratory syndrome (PRRS), measured as sample-to-positive (S/P) ratio, is highly heritable and has a high genetic correlation with reproductive performance during a PRRS outbreak. Two major quantitative trait loci (QTL) on Sus scrofa chromosome 7 (SSC7; QTLMHC and QTL130) accounted for ~40 %

Strategies to Reduce Use of Zinc Oxide by Modulating Gut Microbiota in Pigs

Zinc (Zn) plays an important role in the metabolism of swine and as such is an essential trace element for growing pigs, according to Nutriad. Applying a sound SANACORE EN strategy can make a real difference for producers that want to limit the use of zinc oxide in pig feeds. Zinc deficiency may result in

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,

Stimulating Exploratory Behavior in Piglets: Effects on Pre-Weaning Creep Consumption

his study investigated whether pre-weaning creep consumption can be increased through stimulating exploratory behaviour in piglets, and whether this is best achieved through provision of enrichment (E) or through presentation of creep in a large shallow feeder. In order to examine differences between farms , studies were conducted at Prairie Swine Centre (PSC) as well
