Optimization of Response Surface Methodology (RSM) For Estimation of Feed Requirement Broiler Chicken.

In this study, the feed requirement was being estimated to know the most preferred value that is needed by broiler chicken. The broiler chicken was observed to evaluate their growth by the different mix of the parameter in feed formulation. There were three parameters, which are Moringa oleifera (24.5% to 74%), black soldier fly larvae (5% to 25%) and turmeric (0.5% to 1.0%). Meanwhile the responses in this studies were the average daily weight gain (g/d), survival rate (%) and feed conversion ratio. The Moringa
oleifera leaf, black soldier fly larvae and turmeric rhizome were being prepared by the drying technique before being crushed in the powder form and formulated. The 120 starter
broiler chicken was given with crumb form of feed for 14 days for 20 group that consist 6 chicks per group. This optimization studied were conducted by using the Response
Surface Methodology (RSM) technique with Central Composite Design (CCD) method to design the value for the three parameters that needed in the feed formulation. The
models were linear for ADWG, quadratic for SR and FCR does not have model were being chosen by CCD. The effect of the parameter has been studied by using the 3D response surface graph and 2D contour plot. The optimum level for average daily weight gain that predicted by RSM was 6.05g/d which percentages of Moringa oleifera was 7.63%, turmeric was 0.75% and black soldier fly larvae was 15%. For optimum level survival rate was 58.97% which percentages of Moringa oleifera was 49.25%, turmeric was 0.75% and black soldier fly larvae was 31.82%. And for optimum level feed conversion ratio was 0.5 which percentages of Moringa oleifera was 49.25%, turmeric was 0.75% and black soldier fly larvae was 31.82%.
