ABSTRACT
In Egypt, the ambient temperature can stay consistently high for long periods, besides frequent hot and humid hazardous waves. A high temperature of more than 30°C causes heat stress (HS) in birds and is among the most symptoms of stress that impair poultry production. Chromium (Cr) is a trace element and has a beneficial effect Cr on human and animal health. The experiment was conducted to estimate the action of chromium methionine (Cr-Met) supplementation in laying quails (Coturnix japonica) under HS. A total of 180 were allotted to 5 experimental treatments (6 replicates per treatment). Treatments were: 1) Basel diet (BD), 2) 0.2 g Cr-Met/kg diet, 3) 0.4 g Cr-Met/kg diet, 4) 0.6 g Cr-Met/kg diet, and 5) 0.8 g Cr-Met/kg diet. Results showed that the performance traits, including feed conversion ratio (FCR), daily egg number, and egg mass, were affected positively by Cr-Met supplementation (P ≤ 0.05) compared to birds fed BD. All eggshell and interior egg quality traits were not affected by Cr-Met supplementation. Cr-Met administration positively affected yolk total lipid and yolk total cholesterol compared to birds fed BD as their values were decreased. Also, Cr-Met addition improves the concentricity of unsaturated fatty acids (UFA) and significantly suppresses the concentricity of saturated fatty acids (SFA) compared to birds fed BD. Likewise, dietary Cr-Met supplementation improves blood traits, including a lipid profile, kidney functions, and antioxidant profile of laying quails. In conclusion, Cr-Met supplementation to laying quails diets at 0.4 and 0.6 g Cr-Met/kg under HS enhances performance traits, yolk lipid Profile, and blood traits of quails.
