Abstract
Two experiments were conducted to evaluate the growth and egg laying performances of
Japanese quails (Coturnix coturnix japonica) fed diets containing Brewer’s dried grain (BDG)
and Palm kernel meal (PKM). In the first experiment, 540 unsexed two week old quail chicks
with an average initial weight of 38.00g were raised in cages for 28 days using 3x3 factorial in a
completely randomized experimental design. The birds were assigned to nine dietary treatment
groups of 60 quail chicks each with three replicates of 20 birds per pen. The diets were
formulated to be isonitrogenous (25%CP). Water and feed were offered ad libitum. The result of
the experiment showed that average daily weight gain of quails fed control diet was similar
(P>0.05) to those of quails fed diets containing 15%BDG+0%PKM and those fed
15%PKM+0%BDG but was significantly higher (P<0.05) than those on other diets. Feed intake
of quails increased with increased BDG and PKM levels across the treatments. Quails fed diet
containing 30%BDG+30%PKM consumed significantly (P<0.05) higher feed compared to those
fed the control and other diets. The efficiency of feed utilization revealed a downward trend as
dietary levels of BDG and PKM increased. There were significant differences (P<0.05) in the
carcass parameters measured except for dressing percentage, thigh, liver, intestinal weight and
wings which were not significantly affected (P>0.05) by the levels of BDG and PKM fed in the
diet. Also, there were significant (P<0.05) differences in the nutrient digestibility across the
treatment groups with control diet significantly higher than all other dietary groups. In the
second feeding trial, 270 females (point of lay) were used to study the effect of BDG and PKM
based diets on egg production parameters. They were fed nine dietary treatments which were
formulated to be isonitrogenous (22%CP) and iso-caloric (2700kcal/kgME). The result of the
egg quality characteristics showed no significant (P>0.05) difference across the treatments when
compared with the control. However, significant differences (P<0.05) were observed in the egg
production parameters measured. Hen-day egg production, hen-house egg production and peak
egg production of quails fed diets containing 15%PKM+0%BDG, 30%PKM+0%BDG, 15%BD
G+0%PKM and 30%BDG+0%PKM were similar (P>0.05) to the control but significantly
(P<0.05) higher than all other dietary groups. Thus, utilization of BDG and PKM in quails’ diet
at 15% inclusion level during grower phase and at 30% inclusion level during the egg laying
phase resulted in enhanced growth and egg production performance at the least cost.
