Fig 1. Variables in days after starting the trial.

(A) Insolation (hours/week) during the experimental period (Source: adapted from INMET, 2012). We found a correlation between grazing distance from the dung and insolation (P = 0.03). (B) Fecal Egg Counts (FEC) for the three cattle groups. Twenty days after administration of anthelmintic (indicated by an arrow), we found greater values for the High group than Low and Medium (P < 0.01). Data are absolute FEC (±) SE. (C) Mean distance between dung and the grazing site by group. Bar represents arithmetic means (±) SE. Results show a difference between groups (P = 0.05) and days (P < 0.0001).
