The study used 180 Cobb Broilers in a randomized complete block design with a two-factor factorial experiment (RCBD). As opposed to Factor B, which reflects the various dosages of various forms of vitamin E supplements (control, 200 mg/kg, and 300 mg/kg), Factor A was the type of vitamin E supplement provided to the birds (Vitamin E and Vitamin plus selenium). There were no significant differences in the birds' growth performance when given various vitamin E supplement types and dosages in terms of ultimate weight, weight gain, average daily gain, feed and water intake, and feed conversion ratio. The findings of this study led to the conclusion that the performance of broiler growth was not considerably impacted by the use of various vitamin E supplements. Based on the findings, it is advised to use different types of vitamin E supplements in dosages of 200 mg/kg to 300 mg/kg in mediumto large-scale broiler farms in order to enhance the growth performance and heat stress condition of the birds. However, there was a significant difference between treatments in the various amounts of vitamin E.
