Abstract :
In this experiment, 360 one-day-old male broilers of Ras 308 strain were used in a completely randomized design with 6 treatments and 6 replications from the age of 1 to 42 days. Experimental treatments include 1. control (base diet), 2. control diet with 5 mg copper-methionine, 20 mg manganese-methionine and 5 mg iron-methionine (CuMnFe), 3. control diet with 40 mg gram of zinc-methionine, 20 mg of manganese-methionine, 5 mg of iron-methionine (ZnMnFe), 4. control diet with 40 mg of zinc-methionine, 5 mg of copper-methionine, 5 mg of iron-methionine (ZnCuFe), 5. Control diet with 40 mg of zinc-methionine, 5 mg of copper-methionine, 20 mg of manganese-methionine (ZnCuMn), and 6. Control diet with 40 mg of zinc-methionine. 5 mg of copper-methionine, 20 mg of manganese-methionine, 5 mg of iron-methionine (ZnCuMnFe). Regarding the concentration of zinc, copper and manganese elements in the liver, the birds receiving the ZnCuFe, CuMnFe, ZnCuMn, ZnCuMnFe treatments showed a significant increase compared to the control birds. In terms of feed consumption and weight gain of ZnMnFe treatment birds and in terms of feed conversion ratio, CuMnFe treatment birds were in better condition than the birds of other treatments and the control treatment. Statistically, except for the amount of elements in the liver, none of the treatments had a significant effect on the measured parameters.
