| Abstract | ||
| This experiment was conducted to evaluate the effect of vitamin A injection of hatching eggs with different concentrations on some blood characteristics of broiler chicken. Six hundred eggs hatching (Hubbard) were divided into four groups (150 eggs / group). Treatment groups were distributed as follows: T0 control group (without injection), T1, T2 and T3 injected by 100, 150 and 200 I.U. vit. A respectively at age zero (before incubation). The blood physiological characteristics were studied at 21 and 35 days after hatching. The data showed that vitamin A injection led to significantly (P<0.05) elevated in packed cell volume (PCV), total white blood cells count (WBC), percentage of lymphocytes and significant decrease (P<0.05) in the percentage of hetrophiles and the ratio of H/L, in all treated groups, especially in T1. However, the result revealed that there was a significant increase (P<0.05) in the concentrations of total protein and significant decrease (P<0.05) in concentration of uric acid, in blood plasma for T1 at ages of 21` and 35 days. | ||
