Individual preovulatory follicle (POF) sizes in each group. Cows evaluated for inclusion in the experimental groups are shown. Each dot represents a specific cow. Within each group, individual POF values were ordered from lowest to highest. The cow with the highest value received the highest score and subsequent cows received lower scores. Top ranked cows for the LF-LCL group were considered those cows with the highest scores, whereas top ranked cows for the SF-SCL group were considered those with the lowest scores. A similar procedure was conducted using additional variables, such as those associated with the CL and P4 concentrations and a compound ranking score was calculated. In both groups the top ranked cows (filled dots) were used in laboratory analysis and the remaining cows were not. The horizontal line depicts the cut-off value (11.4 mm) specifically for the POF size. Abbreviations: SF-SCL: Small follicle-small CL group; LF-LCL: Large follicle-large CL group.
