The aim of this experiment was to study the effect supplementation of Sreeni herbal (SH) and Vasanthu Sanjeevani plus (VSP) on the growth performance, carcass characteristics, immune status in broiler chicken from day old to 6 weeks of age. 400-day old broiler chicks individually weighed and randomly distributed into 5 dietary treatments with 16 replicates per treatment and each replicate had 5 birds. The first group was kept as a control (T₁) and given the basal diet without antibiotic, second group (T₂) was fed T₁ with antibiotic, T₃ BD + SH Solid gel form thoroughly mixed in feed, T_4-BD + VSP Liquid gel form added to water and T₅ BD + VSP + SH (Moring Sreeni Herbal in feed and evening VSP in water). The results indicated that supplementation of SH (T₃), VSP (T₄) and SH + VSP (T₅) groups resulted in significantly (p<0.05) higher body weight gain and better feed conversion ratio (FCR) compared to control and antibiotic groups at 42 d of age. However, there was significant difference was noticed among SH, VSP and their combination groups in terms of body weight gain and FCR. Supplementation of different dietary groups did not show any significant (p>0.05) effect on feed intake and various slaughter parameters (giblet weight and breast weight) of broilers. However, supplementation of SH, VSP and SH +VSP groups significantly increased the dressing percentage, humoral immune response to NDV titers and Sensory quality parameters compared to other groups. Supplementation of SH (T₃) and SH +VSP combination (T₅) groups significantly increased visible yellowish pigmentation of the skin and leg when compared to VSP (T₄), control and antibiotic groups. Hence, sreeni herbal and vasanthu sanjeevani plus may be used to produce herbal chicken without using any antibiotics in broilers.
