BACKGROUND Although calcium inhibits zinc bioavailability in rats, especially from high-phytate diets, the effect of calcium on zinc absorption by humans from practical diets remains unclear. OBJECTIVE The objective was to test the inhibitory effect of dietary calcium, in Western diets with high and low phytate content, on zinc absorption. DESIGN Using a 2 x 2 factorial design, zinc absorpt...

with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

Low nutritive value and suitability of barley as a feedstuff for broilers is mainly due to its non-starch polysaccharides. An experiment was carried out to evaluate if diets high in barley alter the mechanisms responsible for the absorption of nutrients across the intestinal epithelium of broilers, using D-xylose absorption test. Thirty, 14-d old male broiler chicks (Ross 308) with similar body...
