Meeting the growing global demand for animal protein requires improving livestock productivity. However, diets designed to increase cattle performance can sometimes upset normal digestion and create environmental challenges. This study evaluated feed additives, including buffering agents and plant extracts (tannins and saponins), as tools to improve nutrient use and reduce digestive disturbances in cattle. A commercial buffer (BRIC), containing alkaline minerals and plant extracts, was compared with plant extracts alone and with sodium bicarbonate, a commonly used buffer. All external buffers helped control rumen acidity to a similar extent, but BRIC also shifted fermentation toward compounds that provide energy to the rumen wall, which may support better nutrient use in cattle fed these diets.
