fermentation and the host’s health. The goal of this studywas to evaluatewhether processing of barley grain with 1 or 5%lactic acid (LA) and 1 or 5% tannic acid (TA), without or with an additional heat treatment (1% LAH or 1% TAH), may affect microbial ruminal abundance, fermentation profile, and nutrient degradation in vitro. RESULTS: Processing with LA lowered (P < 0.05) the concentration o…
