Sow mortality, especially due to prolapses, has increasethe past 5 years in the US swine industry.It has become a significant welfare and production issueNo good understanding of root causes are known at thistime.National Pork Board Released an RFP in October, 2017

Notification of funding
Interviews for Extension Program Specialist
Conference calls with
collaborators to enlist sow

bjectives of the Projectentification of risk factors associated with Pelvic Organ Prolapse in the US serd.
Establish network of industry partners and Sow Farm Managers (target was 60-80 sow fDevelop herd and individual sow survey tool and use it on farm.Establish communication and advisory network of producers, allied industry, university fa
and staff.Establish an accessible repository of data, samples and information.
his is a hypothesis generating project. – It is expected to provide data used to justify pursuing future
research studies that test specific hypotheses.

Examples of Data Being CollectedHerd factors: Sow farm inventory, gestation and lactation diet parameters, distillers dry grain usage, feed type (i.e. pellmash), mycotoxin binder usage, bump feeding, prior mortality and prolapse incidence at the farm, disease history, gilt sbreeding.
Facility factors: Water and feed delivery systems, sow housing type (i.e. pen or stall), gestation pen or stall hygiene, environmental conditions.
Management factors: Artificial insemination hygiene/cleanliness, farrowing assistance strategies, sow feedback and vaccinations, protocols on gestation pen/stall management, culling criteria and strategies.
Animal based measures: Data will be collected on sows that are at specific stages of production, assistance on previofarrowing, genetic background, lameness score, perineal region score, tail dock length, genital-anal distance, body condscore.
Records and data integrity: Prior year sow production and mortality records will be extracted and communication on hrecords were created with farm staff to ensure causes of mortality are accurately defined.
Sample Banking: We will collect representative fecal samples, feed samples, water samples, and swabs of gestation pens/stalls for future distribution and analysis if warranted.

Mortality and Prolapse Record Sheet
Scope of the projectWeekly mortality and prolapse data submitted weekly by:
104 Farms 85 farms in 13 larger systems 19 independents
Almost 400,000 sows15 states
Iowa Pork Industry Ce
Individual Animal Measurements
Scope of the projectOn‐site visits completed on:
62 of the 104 farmsOver 5000 sows individually measured11 of the 15 states4 people collecting data on visits

Currently in Progress
eed sample analysis in progress– Proximate analysis (CP, Ca, P, Na, NDF, Se, Zn, etc.)– Particle size– Mycotoxin analysis ontinuing to collect information for each farm (i.e. historical production-means clustering to characterize patterns in POP incidenceaboratory analysis on a few biological samplesontinued collection of weekly prolapse and morality dataevelopment of a less subjective vulva score
Questions We Are Still Working On rying to Answer . . . Nutrition Nutrient composition Ingredient levels and sources Mycotoxins Laxatives Antibiotic pulses in the feed
GeneticsDisease outbreaks and health status Parity and performance information like total born Relaxin and other endocrine factors
Iowa Pork Industry Ce
Discussion and Thoughts for the utureA lot has been done in 6 months and a lot more to do…Significant analysis remains to be done on A LOT of data-some still being collected. Conduct additional projects on high and low incidence farms Endocrine assays Genetic approaches Nutritional contributions Etc.
Ultimately to design and employ on farm mitigation studies.
