Abstract:
The experiment was conducted in 2019 in Salamieh to study the effect of using different ratios of dried cultivated barley in broiler rations on some productive parameters. 112 broilers (Ross 308 hybrids), 1 day old, were used in this research Birds were divided into 4 groups and each one included 28 birds; all groups were similar in term of heating, ventilation, and all other management treatments except for feeding methods which were related to research plan. Groups of birds were fed by traditional rations. The control group (G1) was fed by a commercial feed while the other groups were treated by adding a dry cultivated barley to its commercial rations by 10 %, 15%, and 20% to the groups G2, G3 and G4, respectively. Birds were slaughtered at 6 weeks old. The results indicated no significant differences (P ≥ 0.05) among experimental groups for hemoglobin, sugar, cholesterol and the number of erythrocytes at the 21 and 42 days old, but highly significant differences (P<0.01) were observed in the total protein concentration between the birds in fourth group(G4), where the adding of the grown barley by 20% comparing with control group at 21 days old, There are also significant differences (P<0.05) in protein ratio Where he excelled group(G4), with the control group birds at 42 days old.
