AbstractThe feasibility of broiler chicken over the phenomenon of compensatory growth after attesting to make its growth slow by using early qualitative feed restriction program had been studied , and its Impact on the qualities of productivity characteristics . The study included experiment with three levels of early qualitative feed restriction during (8-21 days) as well as on the treatment of control ad libtum then all the birds brought to feed free for the remainder of the study ( at the end of the 7 th week ) each levels included three replicates each of 25 birds for a replicate (75 birds / treatment) . Results of this experiment can be summarized as follows of feed for birds fed treatment 10% sawdust as comparison with control grow, while it showed a significant decrease in body weight of birds fed 30% diluted with soft wood sawdust , a significant decrease in the proportion of total mortality for all levels of restriction . With a decline in the values of the two criteria mentioned for the treatment of 30 % soft sawdust as compared with control at the age of marketing.
