This study was conducted at Poultry Farm of Animal production Dept., College of Agriculture, University of AL-Qasim Green to investigate the effect of adding different levels of nano boron to the diet of broiler chickens Ross 308 on some blood parameters. 180 broiler chicks Ross 308 day-old were randomly assigned to four treatments (with 3 replicates per treatment and 15 chicks per replicate). The treatments were as follows: The first treatment was control group, which was free from any addition. The second treatment represented the addition of 40 mg nano-boron/kg feed, while the third treatment represented the addition of 60 mg nano-boron/kg feed and the fourth treatment represented the addition of 80 mg nano-boron/g feed. The studied characteristics were i.e, red blood cell account, hematocrit, hemoglobin concentration, mean corpuscular hemoglobin (MCH), corpuscular hemoglobin concentration (MCHC), corpuscular volume, white blood cells account and differential leucocyte count. The results of the study did not show significant differences between the experiment treatments in the number of red blood cells account, hemoglobin concentration, percentage of haematocrit, MCH and MCHC at 21 days age. The value of MCV, recorded the highest concentration for the first treatment (control). The fourth treatment (addition of 80 mg nano-boron particles/kg feed) showed an increase in the red blood cells account and MCHC significantly (P<0.05) at 35 days age. As for the hemoglobin concentration and percentage of haematocrit, no significant differences were recorded between all experiment treatments. The results showed the superiority of the first treatment (control) in both the value of MCV and the value of MCH compared to the fourth treatment. The treatments of nano-boron had a role in raising the immune traits for the bird at 35 days age, where a significant improvement (P<0.05) in white blood cells account and the highest percentage of Lymphocytes (L) and the lowest percentage of (H/L) recorded compared to control treatment, while no significant differences in the percentage of Heterophil cells (H) between bird groups. It concluded from this experiment, that the addition of nano-boron to the ration can lead to improve in some blood parameters of the broiler.
