Effects of wet corn gluten feed and intake level on diet digestibility and rumen passage rate in steers

Including 40% wet corn gluten feed (WCGF) in the diet increased total tract digestion of organic matter and neutral detergent fiber (P\u3c0.01), reduced total volatile fatty acid concentration (P\u3c0.01), increased rumen NH3 concentration (P\u3c0.01), increased rumen pH, and tended (P\u3c0.06) to increase total tract digestion of starch. Furthermore, WCGF increased rumen passage rate of solid digesta (P\u3c0.01) compared to diets containing no WCGF. Limit feeding reduced total tract digestion of organic matter and neutral detergent fiber (P\u3c0.01), decreased total volatile fatty acid concentration (P\u3c0.01), increased rumen NH3 concentration (P\u3c.01), increased rumen pH at 0 and 12 hours after feeding, reduced rumen pH at 4 hours after feeding, and increased rumen liquid passage rate (P\u3c0.02)
