Eight crossbred steers fitted with ruminal and duodenal cannulas were randomly assigned to two replicated 4 x 4 Latin squares to evaluate the effects of crude protein (CP) levels on microbial protein synthesis efficiency and in situ degradability of nutrients. Animals received a control diet containing Tifton 85 bermudagrass hay or the control diet supplemented with urea, soybean meal or corn gluten meal-60. Ruminal pH and concentration of ruminal ammonia (NH3-N) were determined in the ruminal fluid at 0 (pre-feeding), […]
