This experiment was conducted in the fields of the Department of Animal Production - College of Agriculture - University of Basra from the period 11/19/0220 to 12/23//2020 to know the effect of adding the plant additive PFA consisting of (nigella - anise - thyme) to feed and water over time periods. Different on some immune traits of broilers type ROSS,308. The experiment was carried out using a completely randomized design and a factorial experiment on 252 unsexed chicks distributed into (7) treatments for each treatment (3) replicates for each replicate (12) chicks area of each replicate (1 x 1.5 m 2 / replicate). The plant additive PFA was added to (6) treatments with different time periods in the feed And water, except for the control treatment, was not added to it. The results showed that all treatments of addition to feed or water were superior to the control treatment in the immunological characteristics studied in the experiment, which is the level of balance of the intestinal flora in the jejunum region of the intestine (total bacteria, lactic acid bacteria, E.Coli) as well as the measurement of the volumetric standard of antibodies against Newcastle disease and Kimboro disease, and measuring some parameters of oxidation in the blood serum of broilers at the age of 35 days, which is a measurement (SOD, G-PX, MDA).
