The effect of parent age and hatching egg weight on productive parameters of broiler fed on vegetable mixtures

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 hatching 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.
