From: Place conditioning as evaluation of affective valence in piglets
Place conditioning results for Trial 1 (Sham vs. Castration, young piglets, 2 treatment sessions of 2 h each). All piglets received both treatments between pre-test and test. Symbols represent significance (*P < 0.05) or tendency (‡P < 0.10) in changes between pre-test and test for each treatment (left: latency to enter, right: total time spent in the pen).
