Abstract: A total of 300, one day-old commercial broiler chicks were procured and randomly distributed into 30 subgroups means six dietary treatments with five replicates per treatment and each replicate had ten birds. Feeding trial was conducted for 42 days. All the birds were offered maize- soybean based basal diet which was formulated as per BIS (2007) to fulfill the metabolizable energy (ME) and crude protein requirements of broilers. The first group was kept as a control (T1) and given the basal diet without antibiotic while in second group (T2) basal diet with antibiotic, third (T3), fourth (T4), fifth (T5) and sixth (T6) groups were supplemented with giloy powder @ 0.25, 0.50, 0.75 and 1%, respectively in the diet. Feed intake (g/bird), body weight gain (g/bird), FCR and carcass traits showed significant (P<0.05) improvement as the level of giloy powder was increased. Dietary supplementation at the rate of 0.50 %, 0.75% and 1% giloy powder resulted in significantly (P<0.05) higher DM metabolizability, nitrogen metabolizability and gross energy metabolizability as compared to control group and antibiotic group. Quality of the breast and thigh muscles in terms of ether extract and crude protein improved at 0.50%, 0.75% and 1% giloy powder supplementation. Hematological parameters including RBC and WBC were found significantly higher in T4, T5 and T6 groups, while no effect on % of heterophil and increased % of lymphocytes led to reduce heterophil: lymphocyte ratio and lowest ratio was in T4 group. Significant reduction in serum cholesterol and triglycerides levels was observed in giloy supplemented groups. Inclusion of 1% giloy resulted in significant reduction in LDL as compared with control. Higher count of Lactobacilli and a significant reduction in E.coli count was recorded in giloy supplemented groups. Villus height: depth of intestinal crypts of the experimental birds ranged from 5.62 (T1) to 7.18 (T4) under different dietary treatments and greatest effect was recorded in 0.50% giloy supplemented group because of maximum villus height in this group. The relative mRNA expression of TLR 2 was found to be enhanced (P<0.05) in T4, T5 and T6, while, TLR 4 showed significant down regulation as compared to control. A non-significant difference was observed on expression of relative mRNA levels of TLR 7 in the blood of birds. Thus, the dietary supplementation of giloy powder led to significant improvement in the growth performance, nutrient metabolizability, and hematological indices; possess potent immunomodulatory, antioxidant properties and gut microbiota stabilizing effects, thereby help in achieving a profitable and sustainable poultry
