Description
FerAppease® Bovine 1000 mL is a premium, topical pour-on calming solution manufactured by Fera Diagnostics & Biologicals. It is a synthetic analog of the Maternal Bovine Appeasing Substance (mBAS), a naturally occurring pheromone secreted by lactating cows to calm their young.
This 1000 mL (1 Liter) multi-dose bottle is engineered to dramatically reduce physiological stress and threat perception in cattle during routine farm operations.
