Dry rolled maize and high-moisture sorghum grain (HMSG) were supplied in respective combinations of 100 and 0, 75:25, 50:50, 25:75 and 0:100% at 2% of body weight (DM basis) to heifers equipped with ruminal, duodenal and ileal T-type cannulae. Total tract nitrogen digestibility decreased linearly with the addition of HMSG. Feed N digestion in the rumen and ruminal escape of feed N tended to increase quadratically when greater levels of HMSG were added to the diet.
