Objectives: This study designed the completely randomized experimental to replication of AGP in broiler by kelossia odoratissima mozaff and Petroselinum cripum powders on blood serum biochemistry, immunity titer and blood cells in broilers. Materials & Methods: A total number of 160 day-old Ross 308 broiler chicks were wing banded, weighed and distributed in a completely randomized experimental design with 4 treatments and 5 replications of 8 chicks each. Chicks in all the replicates were reared up to 5 weeks of age under uniform standard conditions throughout the study. Chicks in all the replicates were reared up to six week of age under uniform standard conditions throughout the study. Brooding was done till three weeks of age using incandescent bulbs. Each pen was fitted with an automatic bell type drinker and a hanging tubular feeder. Chicks were provided ad libitum feed and water throughout the study. Feeding of test diets commenced at first day of age and continued till the termination of experiment at six weeks of age. The temperature was maintained at 30±1°C in the first week and reduced by 2.5°C per week to 21°C. From day one until day 4 the lighting schedule was 24 h light. At days 5- 49 the dark time was increased to 1 h. Basal diet was formulated and compounded to meet the nutrient requirements of commercial broilers during the starter (0-2 wks), grower (2-4 wks) and finisher (4-6 wks) feed. Results & Conclusion: Results showed, AGP and Petroselinum cripum powder treatments increased AST significantly and decreased ALT significantly in blood serum. kelossia odoratissima mozaff powder increased the Eosinophil blood cell significantly and the all of treatments had not any significant effect on Newcastle disease and Influenza titers.
