Thousands of mares are kept in a constant state of pregnancy. They wear rubber urine collection bags and are confined to stalls so small they cannot turn around.  The foals and mares that can no longer produce are sent to slaughter. The average life of a mare is 12 years.  This is an unethical and immoral practice and must change.  The drug itself has high risks which may include breast cancer and heart attacks.  Woman need to know how this drug is made.
