The basal low and high fiber diets were comprised of conventional feeds (corn, soybean meal, bermudagrass pellets and cottonseed hulls) and contained .175 and .295 μg chromium/g of diet, respectively. In experiment 1, sixteen lambs were restricted fed the experimental diets for 28 days and then fed ad libitum for 14 days. Blood samples were collected pre and post-feeding at the end of the restricted and ad libitum phase. Plasma glucose and insulin were not affected by chromium when lambs were restricted or ad libitum fed. Chromium also did not affect plasma glucose clearance when glucose was administered intraperitoneally at the end of the ad libitum phase. Chromium supplementation lowered fasting (48 hours) plasma glucose concentrations in lambs fed the low fiber diet. Serum free fatty acids tended to be lowered by chromium in lambs fed the high fiber diet, but not the low fiber diet. Serum total and HDL cholesterol were not significantly affected by chromium. In experiment 2, sixteen lambs were fed (restricted) the high fiber diet supplemented with 0 or 10 μg chromium/g, and blood samples were obtained at 28 days. Serum free fatty acids were lower in chromium supplemented lambs at 3 hours post-feeding. Plasma glucose and serum cholesterol were not affected by chromium. These studies indicate that chromium can affect certain metabolic characteristics in lambs. However, effects of chromium were variable and diet dependent.}, number={8}, journal={NUTRITION RESEARCH}, author={SAMSELL, LJ and SPEARS, JW}, year={1989}, month={Aug}, pages={889–899} }
