Abstract:
A total of 160 sexed male broiler chicks of Vencobb strain of day-old age were randomly divided into 4 groups consisting of ten chicks in each group. All the Groups were maintained under same environmental (heat) stress Conditions (mean maximum daily temperature of 38±1 °C, relative humidity (RH) 82.57 ± 1.40%). Group 1 was maintained on control group and groups 2, 3 and 4 were supplemented with stressroak, ayucee and synthetic vitamin C, respectively. All the groups were maintained on iso-nitrogenous and iso-caloric diet for a period of 6 weeks. The performance parameters were recorded at weekly intervals. Heamatological parameters, serum creatinine, blood glucose and Serum Cortisol were carried out on 4^th and 6^th week. The stress control group had a significant (P<0.05) reduction in body weight, Hb and pcv concentration and Creatinine, while FCR, RBC count, blood glucose and Serum cortisol were significantly (P<0.05) increased. Supplementation with poly herbal formulation in groups 2 and 3 resulted in a marked improvement in all the above parameters as compared to those of stress control group. Performance profiles of Ayucee supplemented group 2 was on par with synthetic vitamin C supplementation.
