A 8-wk study was conducted to evaluate the effects of supplementing laying hen diets with high levels of chromium (chromium chloride, CrCl3.6H2O), vitamin C (L-ascorbic acid) and their combination on productive perfonnance, egg quality and some blood constituents under Egyptian summer conditions (28.7-32.5°C). One hundred and twenty Hy-line White laying hens (32wk of age) were evenly distributed to four experimental groups of 30 hens with ten replicates of three hens each.
