Copper Super-Dosing Improves Performance of Heat-Stressed Broiler Chickens through Modulation of Expression of Proinflammatory Cytokine Genes

Figure 1

Maximum, minimum, and average daily temperature of the experimental room measured during the period of experimentation (1–35 d). Temperature was measured daily at hourly intervals and averaged on a 24 h basis to be plotted. The shaded area indicates the standard ambient temperature to be maintained for optimum production (Cobb Broiler Management Guide, 2013 available from http://www.cobb-vantress.com). The mean maximum temperature was 35.27°C (32.9–36.7°C), and the mean minimum temperature was 27.22°C (26.2–29.4°C).
