Pelvic Organ Prolapse project

Sow mortality, specifically as the result of pelvic organ prolapses, has significantly increased in recent years in the U.S. swine industry. This recent increase in prolapses has been reported across different regions, frustrating producers and veterinarians alike primarily due to lack of mitigation strategies, or even the ability to execute mitigation-based research projects. In 2018, the Iowa Pork Industry Center received funding from National Pork Board to lead an industry-wide effort in identifying specific areas that may be contributing to the increasing incidence of prolapses. 



The full final report from the initial Pelvic Organ Prolapse study is now available for download! 

Take-home points:  

• An industry-wide survey was conducted with 104 sow farms representing approximately 400,000 sows and nearly half of the US swine industry, including large integrated companies and many independently owned sow farms.

 • Multiple factors that may contribute to POP in sows were identified, enabling the design of subsequent studies in specific areas of interest. 

• Many areas of presumed potential influence on pelvic organ prolapse have been shown to be minimally influential if at all. 

• A perineal scoring system was developed that is reproducible and indicative of risk of prolapse for individual sows.

In order to determine rates of pelvic organ prolapse and  develop solutions, pelvic organ prolapses need to be properly identified and recorded on-farm. This video will help pig caretakers identify and document prolapses. If you would like access to this video and accompanying fact sheet, please fill out this form.
