Background: The range of thermoneutral zone of chickens is narrow, and they become easily susceptible to environmental stress, a common and major concern for poultry causing a production loss. Objective: The present study was designed to comparatively evaluate anti-stress activity of Phytocee™ and Vitamin C in chickens reared under heat stress. Materials and Methods: A total of 600-day-old chicks of Cobb 400 were randomly assigned to 4 groups with 6 replicates comprising 25 birds each (n = 150). G1 served as a normal control (NC) and supplemented with Vitamin C at 100 g/ton of feed. G2 served as a heat stress control (HSC), subjected to heat stress (34°C–36°C) without Vitamin C supplementation. G3 and G4 served as positive control and treatment group (TC), subjected to heat stress and supplemented with Vitamin C and Phytocee™ at 100 g/ton of feed, respectively. The impact on zootechnical parameters and cloacal temperature was assessed at regular intervals, and blood was collected at the end of the experiment for evaluation of stress parameters, namely heterophil lymphocyte ratio (H:L ratio) and serum corticosterone. Results: Exposure of chickens to heat stress caused a significant decrease in body weight, worsening of feed conversion ratio, higher mortality, and poor production efficiency. Moreover, serum corticosterone level, H:L ratio, and cloacal temperature were significantly increased in HSC as compared to NC. However, supplementation of Phytocee™ in feed significantly ameliorated the negative impact of heat stress in broiler birds. Conclusion: The supplementation of Phytocee™ demonstrated an anti-stress effect in chickens through restoration of serum corticosterone level, H:L ratio, and thermoregulatory mechanism.
