Abstract

Two group trials were run with the ISA Vedette broilers. Each trial lasted 42 days. The intent of each trial was to observe the quality of wheat as the base component of diets (40.23 % in starter, 52.68 % in growth and 54.73 % in finisher). The wheat extract viscosity was determined as 13.70 cPs. Both trials were carried out with reference and trial groups and they differed in the fact that a trial diet was fortified with enzymatic premix with 1.4-endo-β-xylanase and protease (0.1 % in 100 kg). At the end of the feeding period the body weight gain of broilers fed an enzymatic premix-fortified diet was tend to higher and their feed conversion had improved.
