Thie is Okie, my adopted PMU (pregnant mare urine) Foal. Pregnant mare urine is used for making the hormone replacement therapy drug "Premarin". UPDATE January 2004 !- Thousands of pregnant mares need homes! The company that manufactures Premarin has cancelled the contracts of about 70% of their farmers. This means that these farmers no longer have a profession or an income and that their horses ALL have to be sold! Thousands of mares that have already been bred, plus stallions, yearling mares, and some foals are in danger of going to feedlots. Farmers are selling these horses at a great loss just to find them homes. If you are interested in adopting one of these horses, please email me at poniestoo@aol.com and read more about these mares at www.pmufoalquest.com/pmumares.
