Science Page: Introducing Secure Pork Supply

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, we are talking about Secure Pork Supply (SPS).

The goal of SPS is to develop procedures that pork producers, processors, and Federal and State agencies all agree are feasible to allow for the safe movement of animals from farms in an FAD Control Area to harvest channels or other production sites as long as they have no evidence of disease.

Secure Pork Supply

 Key points

  • In the event of a foreign animal disease (FAD) outbreak in the U.S., maintaining business continuity for the pork industry is critical for food security and animal health and well-being.
  • The goal of the Secure Pork Supply (SPS) Plan is to provide a workable business continuity plan.
  • Having the SPS Plan in place prior to a FAD outbreak will enhance coordination and communication between all parties and speed up a successful FAD response.

Science Page: Leman swine conference – A tribute to Dr. Bob Morrison

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

The Allen D. Leman swine conference starts tomorrow!
This year’s Leman Conference will be a Tribute to Bob and what he did during his career and his continuation of the goals upon which Al Leman first founded the conference.
His drive for holistic improvement rather than individual aggrandizement can be seen reflected in session titles like, “Lesson’s From Dr. Morrison: Focus on Work that Matters”, and “Bob Morrison’s Legacy: Applying a Collaborative Approach in a Competitive Industry”.

Bob pushed himself and those around him to do “work that matters”, display integrity, and focus on the industry as a whole. The Leman Conference is an actualization of these values.

How much floor space does a pregnant sow need in a group-housing system with electronic sow feeders?

Sows housed in groups at the UMN facility in Morris

The University of Minnesota – Morris owns a swine research facility which provides an excellent set up to study the behavior of sows housed in groups. In the past few years, swine producers have committed to change the conditions in which the sows are housed in farms and to keep them in groups where they can interact with each other instead of housing them individually. Putting sows in group reminded us that pigs need a hierarchy and that they will compete and fight to establish it. Because space allowance can impact sows behavior we wondered what the optimum floor space is.

Read the entire report on floor space allowance for sows by Dr. Yuzhi Li

Determining floor space allowance for gestating sows can be controversial because more floor space allowance means low output per square footage of the barn and will potentially reduce profitability for producers. On the other hand, floor space allowance less than sow requirement can compromise sow welfare and performance. To answer the question in the title of this article, we conducted a two-year project (titled ‘Determining the Minimal Floor Space Allowance for Gestating Sows Kept in Pens with Electronic Sow Feeders’). The project was partially sponsored by the National Pork Board, and the research team includes Yuzhi Li and Lee Johnston from the WCROC in Morris, and Sam Baidoo from the SCROC (Southern Research and Outreach Center) in Waseca.[…]

M.hyopneumoniae: knowledge gaps for improved disease control

Enzootic pneumoniae is a chronic respiratory disease caused by Mycoplasma hyopneumoniae in pigs. It has been present in the industry for decades and causes significant economic losses. Yet, control methods like vaccination have not been able to contain the disease. Why is that? What information are we missing to design more effective control methods? This is the goal of the review paper co-authored by Dr. Maria Pieters from the University of Minnesota.

Focusing on various aspects of the disease like epidemiology, pathogenicity, diagnostics, and control measures, this publication regroups all the knowledge we currently have of Mycoplasma hyopneumoniae and identifies what we need to investigate to improve disease control.

Update on Mhyopneumoniae infections in pig Pieters 2017

Abstract:

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary pathogen of enzootic pneumonia, a chronic respiratory disease in pigs. Infections occur worldwide and cause major economic losses to the pig industry. The present paper reviews the current knowledge on M. hyopneumoniae infections, with emphasis on identification and analysis of knowledge gaps for optimizing control of the disease. Close contact between infected and susceptible pigs is the main route of M. hyopneumoniae transmission. Management and housing conditions predisposing for infection or disease are known, but further research is needed to better understand M. hyopneumoniae transmission patterns in modern pig production systems, and to assess the importance of the breeding population for downstream disease control. The organism is primarily found on the mucosal surface of the trachea, bronchi and bronchioles. Different adhesins and lipoproteins are involved in the adherence process. However, a clear picture of the virulence and pathogenicity of M. hyopneumoniae is still missing. The role of glycerol metabolism, myoinositol metabolism and the Mycoplasma Ig binding protein—Mycoplasma Ig protease system should be further investigated for their contribution to virulence. The destruction of the mucociliary apparatus, together with modulating the immune response, enhances the susceptibility of infected pigs to secondary pathogens. Clinical signs and severity of lesions depend on different factors, such as management, environmental conditions and likely also M. hyopneumoniae strain. The potential impact of strain variability on disease severity is not well defined. Diagnostics could be improved by developing tests that may detect virulent strains, by improving sampling in live animals and by designing ELISAs allowing discrimination between infected and vaccinated pigs. The currently available vaccines are often cost-efficient, but the ongoing research on developing new vaccines that confer protective immunity and reduce transmission should be continued, as well as optimization of protocols to eliminate M. hyopneumoniae from pig herds.
