Effectiveness ratios of zinc and copper in the diet on the performance of quail under heat stress

The experiment to investigate the effect of different ratios of copper and zinc in the diet on the performance of quails was conducted under heat stress. A total of 144 chicks of 10 days from the Japanese race were reared for 47 days. The experiment in a completely randomized design with 6 treatments and 4 replications of 6 broilers each category. . Treatments, normal control groups under stress (Cu 1.5 to 88), copper lower than control (0.75 and 88), more copper than controls (3 and 88), on less than controls (1.5 and 44) on more than controls (1.5, 176), respectively. The results show that the control group and the less stress from witnessing the highest weight gain than the control group was normal and of course, between these two groups, control stress better effects as weight gain was higher (p<0.01). The intake of more copper than the control group compared to the control group was normal (p<0.05). The feed efficiency of the Group of copper is higher than the normal control group compared to controls (p<0.01). Among the traits of carcass traits only have significant heart (p<0.05) were higher than the control group than the control group with the lowest weight of the heart is normal. In conclusion, we have better effects than the control group, and as Copper was the best treatment.
