A study was conducted on the effect of roxazyme G2G on the nutritional value of rice bran in order
to reduce the cost of feeding broiler chicken. Eight week feeding trial was carried out study using day old Anak
Strain of broiler. Four groups of fifty birds each were fed two diets that contained 10 and 20% rice bran w ith
or without Roxazyme G2G in a factorial design. Data were collected on performance, nutrient utilization,
carcass characteristics and intestinal tract length. At starter and finisher phases Significant (p<0.05) depression
were observed in Average Daily Gain (ADG) when rice bran was increased from 10 to 20% in the diets (25.60
and 40.20 g versus 22.10 and 36.10 g, respectively). This effect was reversed when enzyme was added.
Increasing the rice bran from 10 to 20% reduced (p<0.05) feed cost but increased production cost which was
reversed when diet was supplemented with enzyme. Birds fed 20% rice bran had lower (p<0.05) live weight
and nutrient utilization than those fed 10% but which w ere improved when enzyme was added. Diets had no
effect on feed intake and mortality. Gizzard weight and gastro-intestinal tract length of birds fed 20% rice bran
were higher (p<0.05). It was concluded that 10% rice bran can be included in broiler diets but may be increased
to 20% when roxazyme G2G is added.
Key words: Carcass characteristics, enzyme, feed intake, Gallus gallus, gizzard weight, intestinal tract length, production cost, weight gain
