What is a P.M.U. Horse?

Premarin is a very common drug prescribed to millions of women worldwide as a hormone replacement therapy. The name stands for PREgant MAres uRINe, as the drug is produced from the hormones present in the mare's urine. The horses used to produce this drug are referred to as "PMU" horses, for short.

The Problem With Premarin

Premarin is created by collecting the urine of pregnant mares. The mares are kept in small standing stalls in order to limit their movement, so not to displace the urinary bladder bags used to collect every drop of urine. The mares are kept in this manner for a lengthy portion of their pregnancy, normally about six months. Once the mares are full term and ready to deliver, they are turned out to have their foals. The mares are able to nurse their foals until weaning age, about 4 months, at which time they are separated and the mare is bred back to repeat the whole process again. This cycle of breeding has created an overabundance of unwanted foals, most of which are sold to the slaughter industry.

PMU farms used to exist all across the USA, and were also prevalent in Canada. Conditions at PMU farms vary, and some farms work very diligently to place their unwanted foals. Many others are not as responsible. Due to increasing pressure of animal welfare regulation, and public outcry over the horrible fates often suffered by the foals, current PMU production has moved overseas.

Because of the move overseas, PMU foals are no longer available in the US. On occasion, we do see some of the mares who managed to escape the industry and have now traveled throughout the equestrian community. Most are easily recognizable by a large freeze brand often on the left hip that is usually 3 to 4 numbers.
