Copper and zinc balance was determined from feed, fecal, urine and water samples obtained during the total collections in periods 4 and 7.;Copper and Zn intake and fecal excretion were greater (P<0.05) for horses consuming the organic-chelate supplemented diet. Apparent Cu absorption as a ...
Effects of feeding supplements of calcium, magnesium, manganese, selenium and potassium on dietary copper bioavailability of humans were investigated. Results indicated that the calcium supplements depressed fecal copper losses and improved body copper r
Copper and Zn intake and fecal excretion were greater (P < 0.05) for horses consuming the organic chelate-supplemented diet. Apparent absorption values for all horses were negative. Apparent Cu absorption and retention as a percentage of intake were greater for horses fed the organic chelate diet...
