Abstract

This study was conducted using 390 unsexed day-old Arbor-Acres
broiler strain chicks which, individually wing-banded, weighed and
randomly distributed into 13 experimental groups of similar mean body
weight of 3 replicates each and aimed to study the possibility of partially
replacing dietary protein with canola meal (CM) protein with /without
multicarbohydrase enzymes and its effect on growth performance, some
carcass traits, some blood serum parameters and economical efficiency.
An experimental corn-soybean meal starter and finisher basal diets were
formulated in which dietary protein was replaced by CM protein at
replacement ratios of 16, 32, 48 and 64%. Diets were formulated to be
iso-nitrogenous and iso-caloric being 23% CP & 3000 kcal ME / kg for
the starter diet and 20% CP & 3100 kcal ME/kg for the finisher diet.
Thirteen dietary treatments were compared. One treatment consisted of
the basal diet without CM (positive control diet). Four treatments
consisted of the positive control diet supplemented with 16, 32, 48 or
64% CM without enzyme supplementation (negative control diets).
Eight additional treatments consisted of the negative control diets
supplemented with either Zympex® 008 or Xylam500 enzyme products at
a level of 0.05%. Live growth performance, carcass characteristics,
some blood serum parameters, sensory evaluation of cooked meat and
economical efficiency were determined. From the nutritional and
economical point of view, it could be concluded that substituting CM
protein up to 48% for dietary protein in both starter and finisher broiler
diets supplemented with Zympex® 008 enzyme product at a level of
0.05% has no detrimental effect on broiler chick's growth performance
and gave the best economical efficiency.
