Fig. 3.

The effect of Eimeria Operational Taxonomic Unit (OTU) infection on broiler chicken bodyweight gain (BWG). Groups of eight 21 day old Ross 308 broiler chickens were infected by oral inoculation of (A) OTUx or (B) OTUz oocysts. Weight was measured at the time of infection and 10 days later. Data points indicate individual chickens, with the mean and S.D. presented for each group. Superscript letters identify groups that were statistically significantly different from each other within an experiment (P < 0.05). Note: The scales used on the Y axes vary between panels to improve visualisation of intra-group variation.
