Effect of dietary protein/energy combinations on male broiler breeder performance

A study was conducted to evaluate crude protein level and low energy supply on broiler production parameters. Three hundred Ross 308- day-old male broiler chicks were divided in three basic group and placed in three separate pens littered with wood shavings. Treatments consisted of a control diet (220 g/kg CP), the second diet with a crude protein diet (205 g/kg CP), and the third with a crude protein diet (190 g/kg CP) with the same ratio 1:573-575 KJ/kg ME and crude protein in starter (first 21 days). Finisher (22 day till end ) control diet consisted 200 g/kg CP, the second diet consisted 185 g/kg CP, and the third diet consisted 170 g/kg CP, with the ratio 1: 649- 650 KJ/kg ME and crude protein. Feed intake tended to decrease with increasing crude protein and energy. Feed conversion (g gain per g feed) improved as crude protein and energy increased. Muscle amount in groups K and P1 was statistically much higher (P<0, 01) than in group P2. Concentration of biochemical indicators showed less organism strain in groups fed blends with less crude protein and energy.
