Effect of energy source varieties on biochemical blood traits and carcass sensory evaluation in fattening rations of Awassi lambs


This experiment was carried out at animal field that belonging to College of Agriculture and Forestry/Mosul University in order to find out the best source of energy in fattening rations and to study their effects on some blood parameters and carcass sensory test of Awassi lambs. Fifteen local male lambs after weaning age were used in this experiment and were assigned randomly to three experimental groups.These experimental groups were fed add libitum on three rations containing barley, molasses and rice polishings as a source of energy for 105 day period .The results of this experiment showed that there were significant differences (P≤0.05) on red blood cells count (RBC), hemoglobin level (Hb), packed cell volume (PCV), total protein and high significantly differences (P≤0.01) on white blood cells count (WBC) and albumin among the three treatments. As about the carcass sensory evaluation the statistical analysis showed that there were significant differences (P≤0.05) on tenderness and juiciness traits and also high significantly differences (P≤0.01) on texture, aroma and acceptability between experimental groups as compared to control group. Concluded of this study that the rice polishing diet was used in the third treatment was appeared significant improved on some blood parameters and meat quality when compared with other energy sources in the first and second treatments
