Abstract

This study was conducted to evaluate the effect of feeding graded levels of wheat offal and
hemicell® enzyme supplementation on broiler chicken performance. The experiment involved
the replacement of maize with wheat offal at 0, 10, 15, and 20% levels of inclusion with or
without enzyme hemicell supplementation in a 4 x 2 factorial arrangement in a completely
randomized design. Two hundred and eighty eight day-old Cobs broiler chicks were allocated to
the treatments (n=36/treatment) in three replicates, in a study that lasted nine weeks. Results
obtained showed that final weight and weight gain decreased with increased levels of wheat offal
in the diets, being significantly (p<0.0001) lower in birds on 15 and 20% wheat offal than 0 and
10% wheat offal. Feed intake, feed to gain ratio (FGR), feed cost and feed cost per kg weight
gain increased with increase in wheat offal levels. Feed cost/kg gain increased significantly as
level of wheat offal increased in the diet, being almost twice in the diet containing 20%
compared to the 0% wheat offal diet. There was a significant (p<0.001) improvement in final
weights and weight gains of broilers fed diets supplemented with hemicell®. Feed intake, feed
cost, FGR and feed cost/kg gain significantly decreased with hemicell® supplementation. The
enzyme supplemented wheat offal levels of 15 and 20% showed improvement in weight gain and
reduced feed cost per kg weight gain over non-supplemented birds. The best performance was
recorded in broilers fed 10% wheat offal diet supplemented with hemicell®. It is therefore
recommended that wheat offal could be added in the diet of broiler chickens up to 10% with
Hemicell enzyme supplementation.
