The aim of this study was to investigate the effects of various doses of essential oils (EO) of thyme (TEO) or cinnamon (CEO) on in vitro rumen degradation of protein of a commercial total mixed ratio (TMR) containing 16.4% crud protein (CP). Treatments were TMR without any of EOs (control); control plus 25 µL of TEO (TEO25); control plus 50 µL of TEO (TEO50); control plus 25 µL of CEO (CEO25) ...
