The research was carried out using 1728 broiler chicks (shifer starbro
hybrid), They were divided into eight groups, each one consists of three
replicates with 72 birds in every repetition .The birds of all repetitions were
fattened until 49 days
in separate pen of open type walk ,and on deepbedplate
.All conditions of placement, rearing and feeding were the same for all birds of
repitition in different groups.
The research was carried out on two classes of hatching eggs obtained
from broiler breeder flock ( shifer starbro- Hybird ) 39 and 59 wk of age .
In each class the hatching eggs were graded into three groups according
to their weights.
The hatchi
ng eggs of each group were divided into three replicates .
Eggs of all replicates were incubated in the same incubator . At hatching
(115) chicks were taken from each replicate and fed in separate pen until 7
weeks of age . All conditions of housing, rearing and feeding
( vegetable diets ) were same for all birds of all replications.
