Values are mean ± standard error of deviation. Within a column, values with different uppercase superscript letters differ significantly (P<0.05).

Figure 1.  Oocyst excretion values per gram of faeces (OPG) for each group of chicks. The OPG output in each group of chickens corresponds to days 6 to 9 p.i. with E. tenella and is expressed as the logarithm of the OPG value. Error bars represent the standard deviations. *Significantly reduced oocyst excretion compared with the unsupplemented and infected groups (P < 0.05).
