    abstract = {The present study was designed to evaluate the
effect of the variation of dietary energy density with palm
oil residue on growth performance of broiler chickens.For
this purpose, 162(81 male and 81 female) Cobb 500
broiler of 21 days old (641g) were used. They were reared
from 22-49 days of age. They were randomly assigned to
three treatments groups on the basis of diet energy
content: A0 (2900 kcal kg<sup>&#150;1</sup> of Body weight), A4
(3100 kcal kg<sup>&#150;1</sup> of BW) and A8 (3200 kcal kg<sup>&#150;1</sup> of BW).
Throughout experiment, feed intake, live weight and body
weight gain were recorded at weekly intervals and the
Feed Conversion Ratio (FCR) determined. At the end of
the 49th day, assessment of carcass characteristic was
performed. The cost of feed consumed and the cost of
feed per kg of weight gain were also determined. During
the first week, feed intake (700&plusmn;4.58 g), live weight
(933.66&plusmn;8.7 g) and daily body weight gain (41.9&plusmn;1.46
g)of broiler fed on diet containing 2900 kcal kg<sup>&#150;1</sup> were
significantly higher (p<0.05) than those obtained with
3200 kcal kg<sup>&#150;1</sup> or 3100 kcal kg&lt;sup&gt;&#150;1&lt;/sup&gt;. At weeks 2 and 3, daily
body weight gain (83.61&plusmn;5.44 and 74.09&plusmn;15.63 g,
respectively) and FCR (1.28&plusmn;0.07 and 1.95&plusmn;0.15 g
respectively) of chicken fed on diet energy density of
3200 kcal kg&lt;sup&gt;&#150;1&lt;/sup&gt; were significantly higher (p<0.05). The
carcass weight (1841&plusmn;17.31 g), yield (80&plusmn;17.75%) and
abdominal fat of broiler chicken fed on diet energy
density of 3200 kcal kg<sup>&#150;1</sup> were significantly higher
(p<0.05). The cost of feed consumed, the cost of feed/kg
weight gain and cost of feed/kg carcass decreased as the
diet energy content increased. It can be concluded that the
increase of diet energy to 3200 kcal kg<sup>&#150;1</sup> with palm oil
residue during finisher phase improved growth
performance, carcass characteristic and profitability.}
