Twenty diets of five leaf meals Calliandra sp, Sesbania sp, Leucaena sp, Gliricidia sp and cassava were given into broiler chickens with four dosages 2.5, 5, 7.5 and 10 percent to see several nutrient content effect and also their function order. The nutrient contents as independent variables were Crude Protein (X1), NDF(X2). TME (X3), TDN (X4), Tannin Content (X5), Soluble Protein (X6), X2X4, X2X5, X4X5, X4X6 and X5X6. Average weight gain (Y1) and Feed Consumption (Y2) per chick up to 4 weeks old were measured as dependent variables. The result showed that: Y1=-453.81 + 117.55 X4 - 0.71 X3 - 288.89 X2 - 1.70 X4X6; Y2=-4498.65 + 82.37 X4 + 5.19 X4X5. It is concluded that there are only several variables among all independent variables affecting Y. Coefficient of determination also showed their order function.
