A study was conducted to determine the effect of three native plants from El-Jabal al ELAkhdar, (Libya) on hematological profile, cholesterol and immune response to ND vaccine in broiler chickens. A total of 1260 one-day-old male Cobb chickens were used in the experiment. Chickens were assigned to 7 treatment groups (6 replicates per treatment). The dietary treatments included basal diet with no additives (control), and 6 other dietary treatments (Arbutus pavarii, Salvia officinalis and Zizyphus Vulgaris) each of which was added at the rate of 0.5g and 1g/kg of basal diet. Results explicitly revealed that no significant change in TLC between the treated and control groups has been recorded. A significant heteropenia was recorded at the third week of treatment with 1% A. Pavarii 0.5 S. Officinalis and 0.5 Z. Vulgaris when compared to control group. However, the lymphocytic count show a significant increase (P≤0.05) in all treated groups compared to the control groups. Immunologically, an enhanced humeral immune response was very obvious based upon the significant elevation of antibody titer at the third week of treatment for all groups received 1 % of the three types of plants. Interestingly , cholesterol levels were significantly elevated at the six week of treatment with 0.5 % Z. Vulgaris while highest decline in cholesterol levels were recorded in group that have received 0.5 S. Officinalis.

Abstract In this study, antibacterial, antioxidant and phenolic compounds of raisin extracts was evaluated. Different solvent extraction methods were utilized to extract phenolic compounds from raisin. The phenolic compounds of raisin extracts was determined using HPLC and three compounds were found, catechin, quercetin and rutin. The antibacterial activity of the acetonic extract was tested against four bacterial pathogens viz. Staphylococcus aureus, Pseudomonas aeroginosa, Salmonella typhimurium and Escherichia coli using both disk diffusion and minimum inhibitory concentration (MIC) methods. The acetonic extract exhibited the highest activity against Staphylococcus aureus with zone of inhibition of 14mm and the MIC of 25 mg/ml. However, there was a little activity against E. coli and S. typhimurium. The methanolic extract showed good antioxidant activity as indicated by 2,2-diphenyl-1-picrylhydrazyl free radical assay (DPPH). In conclusion, raisin contains potent phenolic compounds and their application might function as promising natural preservative and antimicrobial agents in food industry and also good antioxidant food that helps to minimize the risk of degenerative diseases. arabic 11 English 86
