The aim of this study was to investigate the influence of different stocking densities
on the growth performance of Ross 308 broiler chickens up to six weeks of age. A to
tal of 216
one
-
day broiler chicks were randomly assigned to three treatment groups based on the stocking
density:
Low (LSD)
=
14
chickens
m
-
2
, Medium (MSD)
=
18
chickens
per
m
2
and High
(HSD)
=
22 chickens
m

, with four replications. Higher body weight gain (TWG) was observed
for the low (2,043.89
g) and medium (2
,
008.03
g) compared to the high (1,901.51
g) density. The
study revealed that chickens of the LSD treatment
consumed significantly (
P
<
0.01) more fe
ed
compared to the HSD chickens. High stocking density (22
m

)
tended to improve feed conversion
ratio compared to medium (18
m
-
2
) and low (14
m
-
2
) stocking density, but the differences were
not significant (
P
>
0.05). From the results of this study
it can be concluded that broiler chicks
can be stocked up to 22 chickens
m
2
, as far as required standards are assured.
