The study involved four treatment groups, including a thermoneutral control (TN-C), a heat-stress control (HS-C), and two groups supplemented with Nuqo RED at different doses (50 ppm and 150 ppm). Results showed that broilers fed with Nuqo RED at 50 ppm showed improved feed intake (ADFI) and weight gain (ADG), recovering about half of the weight gain compared to the TN-C group. The highest improvement in performance was observed in birds fed with Nuqo RED at 150 ppm, which achieved feed intake levels comparable to the TN-C group and the best weight gain of all treatments. Additionally, the feed conversion ratio (FCR) improved by 1.3% in the 150 ppm group, showing a clear dose-dependent effect. Moreover, the trial also measured stress biomarkers such as heat shock protein (HSP70) in liver tissue and levels of corticosterone and Glutathione Peroxidase (GSH-Px) in blood samples. While there was no significant difference in GSH-Px level in this trial, Nuqo RED at 150 ppm significantly reduced the HSP70 levels as compared to the Heat-stress control, indicating a lower stress level in the birds.. These results suggest that Nuqo RED not only improves performance under heat stress but also helps mitigate the physiological impact of stress on poultry.
