Table 3 Recovery in the lumen of the gastro-intestinal compartments, digestibility and losses of dietary nitrogen in rats 5 h after the meal

From: Rapeseed and milk protein exhibit a similar overall nutritional value but marked difference in postprandial regional nitrogen utilization in rats

NS: not significant, PS: protein source, A: adaptation. aTwo way ANOVA; b Recovery in cecum and colon content at 5 h (% of ingested N); cReal ileal digestibility (see Material and methods); d Recovery in body and urinary urea. Means within a row with different letters are significantly different (P < 0.05, Tukey post-hoc test)
