The influence of enzyme
supplementation on performance and digestibility of dry matter and protein
in young broiler chicks was examined for a diet based on triticale supplemented
with different levels of enzyme. In a completely randomized design,
two hundred d-old chicks (Ross strain) were divided into 20 groups,
ten chicks per group. A basal diet containing 65% triticale was supplemented
with zero, 100, 200, 400 and 800 g/kg enzyme and given to four replicates
for 21 days. Added enzyme (xylanase) improved (P< 0.05) body weight,
body weight gain, feed intake and feed conversion ratio. Apparent digestibilities
of energy and protein were increased (P< 0.05) due to supplemental enzyme.
Non-significant improvement was observed in protein and energy efficiencies
by the addition of enzyme. All improvements had a similar trend and
were the highest at 200 g/kg enzyme supplementation. Higher levels of
enzyme had no beneficial effect on measured criteria. The results indicated
that the nutritional value of cereal grains such as triticale can be
improved by supplemental enzyme containing mainly xylanase to the diet
of young broiler chicks.
