Position on the Management of Mares Utilized in the Pregnant Mare (PMU) Collection Industry

Through on-site investigations and peer review of ongoing research, the American Association of Equine Practitioners believes the collection of urine from pregnant mares and care of their offspring as prescribed by the recommended “Code of Practice,” represents responsible management of horses to produce a commodity for the benefit of mankind that should not result in abuse, neglect or inhumane treatment of horses.

The recommended Code of Practice is accessible at   

In June of 2014, The Equine Ranching Advisory Board developed a white paper on “Care and Management of Horses Managed for the Collection of Pregnant Mares’ Urine (PMU)”.  The AAEP acknowledges the thorough nature of this document and believes it is a good resource for parties interested in the management of PMU horses. Unlike the other white papers here, this document was not created specifically by the AAEP; it was prepared by the Equine Ranching Advisory Board, many of whom are AAEP members. It was reviewed for inclusion on this website by the AAEP Welfare and Public Policy Advisory Council. The AAEP does not endorse or support any specific product or company referenced therein. You can read the paper here
