Effects of identification marking methods on latency to eat a novel food item. Data from all mice are displayed (box with bar = median +/− IQR; x = mean), including those who did not consume novel sweetcorn and thus attained the maximum latency of 900 s (n = 12/group). The treatments are as follows: Control = neither mouse was marked; EP = ear-punch; EP+A = ear-punch plus anaesthetic cream; MP = permanent marker on the tail; C-EP = cagemates of EP mice; C-EP+A = cagemates of EP+A mice; C-MP = cagemates of MP mice. ^a Significantly fewer mice consumed novel food than ^b (p = 0.001), but the latencies of mice who did consume food showed no significant treatment effects.
