ARTICLE 74 FEED & ADDITIVE MAGAZINE June 2025 non-encapsulated oregano oil in DOSTO® bi-active ensures that the beneficial effects of oregano oil are distributed throughout the digestive system. Beyond enhancing performance and general well-being, the appetizing nature of oregano oil in the ration can be particularly beneficial in supporting the metabolic health of dairy cows during challenging periods such as the critical first phase of lactation or, crucially, during heat stress. By encouraging feed intake and maintaining gut function, DOSTO® bi-active can help cattle better cope with high temperatures and minimize the negative impacts on their health and productivity. In conclusion, incorporating a combination of rumen-available and rumen-protected oregano oil, as found in DOSTO® bi-active, presents a natural strategy to support cattle, especially in mitigating the detrimental effects of heat stress. By optimizing rumen and intestinal function and encouraging feed intake, this innovative feed additive can contribute to improved well-being and sustained performance, even in high temperatures.
