Abstract :

Ration composition and in particular, the amount of trace elements in the feed has become especially important to increase the economic efficiency and health of the poultry. Trace elements in the diet can affect feed consumption, growth performance and health status in birds by regulating enzyme activities, oxidation-reduction reactions and other biochemical functions. In this experiment, 360 one-day-old male broilers of Ross 308 strain were used in a completely randomized design with 6 treatments and 6 replicates from the age of 1 to 42 days. The experimental treatments consisted of 1. Control (basic 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 and 5 mg of iron-methionine (ZnMnFe), 4. Control diet with 40 mg of zinc-methionine, 5 mg of copper-methionine and 5 mg of iron-methionine (ZnCuFe), 5. Control diet with 40 mg of zinc-methionine, 5 mg of copper-methionine and 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 and 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, 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.
