The coccidiosis lesion score (CLS) is used to determine the presence and severity of infections with Eimeria species (Johnson & Reid, 1970) and can range from 0 to 4 with higher scores indicating more severe lesions. CLS was determined for duodenum, jejunum, and ceca. The total CLS is the sum for all three intestinal parts and can range from 0 to 12. The morphometric evaluation of “dysbacteriosis” referred to as the gut score can range from 0 to 10 (GS) (Teirlynck et al., 2011). Average values and standard deviation (SD) for total CLS and GS, and the percentage of broilers for three categories of scores are provided for days 21, 28, and 35 of the study.
