Growth performance and nutrient digestibility of broilers fed different type of diets and feed additives

Abstract

This research aimed to evaluate the nutrient digestibility and the growth performance of broilers fed a different type of diet (TD) and feed additives (FA). A total of 264 day-old chicks (male, Lohmann) were randomly distributed into 24 pens (11 birds/pen). The experiment was designed by using a 2 x 4 factorial completely randomized design with the main factors TD and FA. The result shows that TD x FA interaction was significant (p<0.05-0.001) for feed intake (FI) and body weigt gain (BWG) of starter broilers. The TD, FA, and TD x FA affected (p<0.01-0.001) growth performance (GP) of growing broilers. TD and TD x FA interaction affected liver weight and the length of proventriculus and gizzard (p<0.05 to 0.001). Except for starch, the TD did not affect (p>0.05) nutrient digestibility (ND) and energy values (EV). Except for crude protein, FA did not affect (p>0.05) on ND and EV. The TD x FA interaction did not affect ND and EV. TD affected (p<0.05–0.001) on FI and BWG)of starter broilers. Except for day 7, FA influenced (p<0.01–0.001) FI and BWG of starter broilers. In conclusion, 1) The addition of Synbiotics and Allzyme SSF-E on Rice bran-sago diet (RSD) improved the GP of birds; and 2) The complex and multi enzymes work well in the rice bran-sago diet  3) RSD produced better growth performance of broiler starter.
