This study examined how broilers up to 38 days of age fared regarding growth efficiency and carcass characteristics concerning selenium nanoparticle activities (SeNPs). A total of 180 one-week-old broiler (Cobb 500) chicks without sex were randomly allocated into three groups, each with six replications of 10 chicks. The trial took 38 days to complete. The three study dietary groups were fed ad libitum feed and water throughout their 38-day of age, along with corn-and-soybean meal-based diets supplemented with 0 (control), 1.5, and 2.0 ml SeNPs (concentration = 5%) /kg diet, respectively. According to the current findings, the SeNP supplementation groups had greater body weight, weight gain, and performance indicators than the control group after 38 days of the feeding experiment. The findings demonstrated that dietary interventions did not affect the amount of feed consumed (FC) per chick per day or the feed conversion ratio (FCR). The conclusion is that adding SeNPs to broiler diets at 1.5 or 2.0 ml/kg increased productivity. In contrast, lower levels of selenium (Se) (1.5 ml/kg diet) showed encouraging results and could be employed as a useful feed additive in broilers.
