Kenney™ formula stallion extender is a great general-use sugar and milk-based extender formula. The extender arrives as two components – the foil packet of dry powdered extender mix and the pre-measured bottle of sterilized water. The combined components produce 100ml of extender. Kenney™ is available in multiple antibiotic options. For the versions with antibiotic, the antibiotic is mixed directly into the powdered extender formula, eliminating the necessity for an extra mixing step.
