ABSTRACT This study aimed to assess the ruminal fermentation of various cottonseed (Exp. 1) and peanut (Exp. 2) meals, each processed using different techniques and exhibiting varying levels of rumen undegradable protein (RUP). Six treatments were evaluated for each feed. For Exp. 1 (cottonseed meal): negative control (conventional meal; Ncontrol), microwave-heated (2 min) with 2% xylose, conventional oven-heated (90 min) with 2% xylose, autoclave-heated (8 min) with 2% xylose, tannin treatment (6% inclusion), and a commercial soybean-based product (Pcontrol). For […]
