Figure 6

Average duration moving and time being before, during and after stimulus presentation (flyover of a Chinook helicopter) in dairy goats. Data are depicted as mean ± SEM. Note that the data of only 3 goats were available for analyzing the effects of the helicopter overflights on alertness of the goats. Results of one-sample t-statistics on the difference scores between values (during minus before), (after minus during), and (after minus before) stimulus presentation are summarized in the lower part of the figures. The list of stimuli presented is shown in Table 1. NS: no effect, p > 0.10; #: marginal effect, 0.10 > p > 0.05; *: significant effect, p < 0.05
