Evaluation of Using Different Ratios of Pronchi-Stop as Commercial Compound with Extract of Eucalyptus Oil on Blood Characteristics of Broiler Ross 308

This study was conducted in the poultry farm - Department of Animal Production - College of Agriculture - University of Kufa from 9/11/2023 to 25/12/2023 for a period of 35 days. The study aims to evaluate of using of Eucalyptus oil extract with the commercial compound Pronchi-stop in drinking water to improve the blood characteristics of broiler. 300 unsexed, broiler chicks Ross 308 were randomly distributed into five treatments (each treatment included 60 chicks, with 3 replicates, and each replicate include 20 birds). The treatments were as follows: Control T1 (without addition), T2, T3 adding 0.5 or 1 ml of pronchi -stop /1 L of drinking water respectively, T4, T5 adding 0.5 or 1 ml of Eucalyptus oil extract/1 L of drinking water respectively. At marketing age, blood samples were collected from birds for each replicate to study the cellular blood characteristics (RBC, WBC, PCV, Hb) and biochemical blood characteristics (glucose, cholesterol, triglycerides, total protein, albumin, globulin) in blood serum. The results indicated that: No significant differences in cellular and biochemical blood characteristics between all experimental treatments compare to control group, except in estimation of total protein concentration. A significant superiority (P≤0.05) for T2 and T5 over the control group, while no significant differences between T2, T3, T4, and T5.
