This study aimed to assess the effects of selenium and selenium nanoparticles with chitosan on broiler chickens during heat stress. In this study, total 336 chicks were raised. These birds were split into seven groups, each with six sets of eight birds, depending on the treatments they received. There were two control groups: one with the regular diet (negative control) and another with the regular diet plus heat stress (positive control) known as A and B Groups respectively. The remaining groups were as follows: Group-C (Basal diet+0.3mg/kg selenium), Group-D (Basal diet + 0.3mg/kg nano selenium + heat stress), Group-E (basal diet+300mg/kg chitosan+heat stress), Group-F (basal diet+0.3mg/kg selenium+300mg/kg chitosan+ heat stress) and Group-G (0.3mg nano selenium + 300mg/kg chitosan/+basal diet + heat stress). The various parameters were analyzed, including drip loss, cooking loss, lipid profiles, mineral content, and bone characteristics was significantly improved in Group G, receiving nano selenium and chitosan under heat stress. Moreover, Group G showed higher selenium, calcium, and phosphorus content in breast muscle tissue, along with tibial bone characteristics such as weight, length, wall thickness, density, and medullary canal diameter as compared to group-B. Although weight/length index showed no significant differences, Group G demonstrated the highest Tibiotarsal Index (TTI) and Robusticity Index (RI). These findings suggest the beneficial effects of nano selenium and chitosan supplementation, particularly evident under heat stress conditions.
