Abstract
This study was conducted at the Poultry Farm of Animal production Dept., College of Agriculture, University of AL-Qasim Green to investigate Study the Effect of adding different levels of Nano Boron to the Diet in some blood parameters of broiler Chickens Ross 308 . Use the 180 broiler chicks Ross 308 day-old were randomly assigned to four treatments (by 3 replicates per treatment 15 chicks per replicate), and treatments were as follows : First treatment: control group: free from any addition. The second treatment: experimental added to it 40 mg nano-boron / kg feed, the third treatment: experimental added to it 60 mg nano-boron / kg feed and the fourth treatment: experimental added to it 80 mg nano-boron /kg feed. The experiment included a study of the following characteristics : red blood cell account, hematocrit, hemoglobin concentration, Mean Corpuscular Hemoglobin (MCH) , Mean corpuscular hemoglobin concentration (MCHC), value of Mean 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, the percentage of Haematocrit, Mean Corpuscular Hemoglobin (MCH) and Mean corpuscular hemoglobin concentration (MCHC) at 21 days age. The value of Mean Corpuscular Volume (MCV), where the first treatment (control) recorded the highest concentration for it. The fourth treatment (addition of 80 mg nano-boron particles/kg feed) showed an increase in the red blood cells account and the Mean corpuscular hemoglobin concentration (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 Mean Corpuscular Volume (MCV) and the value of Mean Corpuscular Hemoglobin (MCH) compared to the fourth treatment. The treatments of the nano-boron have a role in raising the immune traits for the bird at the 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 experience, that the addition of nano-boron to the ration can lead to improve in some blood parameters of the broiler .
Key words : nano-boron , blood parameters , broiler
