Figure 4.

The number of E. tenella developmental stages (meronts, gamonts, and oocysts) in the cecum of infested and treated groups. T3: E. tenella-infected (positive control birds), T4: E. tenella-infected and treated with SeNPs (500 µg/kg diet), and T5: E. tenella-infected chicks and treated with the anticoccidial agent (sulfadimidine, 16% solution 8 mL/L of drinking water). The values are presented as mean ± SE. Lowercase letters (a–e) above columns indicate the significant differences between different treatments on the count of oocyst stages using the LSD test at P < 0.05.
