ISSUE FOCUS FEED & ADDITIVE MAGAZINE May 2024 33 sults in this field trial highlight the potential of phytogenic feed solutions to revolutionize dairy farming by providing solutions that may support farm profitability and environmental sustainability (Graphic 1). A phytogenic feed solution was tested in a field trial in China, including a local diet. This product has shown to improve milk production and energy corrected milk significantly, together with an improvement of the milk quality (Table 1). The phytogenic feed solution tested in this trial combine essential oils, spices, and triterpenoid saponins. The increase in milk production observed in this trial was likely due to an improvement in energy efficiency and protein efficiency in dairy cows. It works by stimulating fiber digestibility in the rumen and enhancing starch and fat digestibility in the small intestine. Plant-based products like phytogenics, have shown promise in supporting optimal feed efficiency and reducing costs in dairy farming. The following effects of phytogenics in ruminants are observed and proven: • Support of optimal level of rumen undegradable protein hence improving the metabolizable protein level • Improving the microbial protein synthesis • Help minimizing NH3 losses • Improving protein digestibility in the small intestine CONCLUSION Phytogenics may offer a solution to optimize feed efficiency, support margin in dairy farming, and reduce costs in dairy farming. By focusing on optimal feed intake and thereby enhancing nutrient utilization, dairy farmers can navigate the challenges of feed costs and milk prices while maintaining profitability and sustainability in their operations. Integrating these solutions into dairy farming practices can lead to a more efficient and profitable industry, benefiting farmers, consumers, and the environment alike. *This article only provides scientific information and should not be construed as marketing claims or guidance.
