Sheep cannulated in the rumen, duodenum and ileum were used to study absorption of minerals from diets: I. barley only (B), and II. 70% (DM basis) barley + 30% SO2 treated wheat straw (B+S). Na and K were highly absorbed from both diets and almost completely recovered in the urine. Ca apparent absorption was low: 12.1% and 13.4% in the B and B+S treatments, respectively. The Mg net absorption in the rumen was significantly higher in diet B than in diet B+S; the difference in total tract apparent absorption of Mg was, however, much smaller and not significant: 44.5% and 38.2% for the B and B+S treatments, respectively. Animal variation in P absorption was very large, ranging from 5% to 66%. There was a trend toward net secretion of Cu, Zn and Mn in the stomachs, the trend being 2-3 times higher in the B+S than B diet. Generally, the apparent absorption of Cu, Zn and Mn was lower in the B+S than B diet; however, the most notable difference was with Cu absorption. © 1991.
