Hippex
Hippex is an equine semen extender for fresh use or for refrigerated transport, with excellent preservation capacity that makes sperm centrifugation unnecessary for most stallions.
It contains a mixture of shielding proteins, antioxidants, and lipids that protect the sperm cells.
It retains acceptable cell motility and viability for at least 3 days; analysis of pregnancy data covering 60 stallions showed a pregnancy rate of 75 - 80%!
