A Representation of progression of the weight of the animals included in the study during the 9-month growth period (monthly measurement) (n = 10–21/experimental groups). B ITT results were extrapolated into an area under the curve value which was used for the statistical comparison. Results were represented as bar graphs or violin plots. Differences between groups were analyzed using ANOVA and Tukey’s. Significance was represented as follows: *p < 0.05, **p < 0.01 and ***p < 0.001 (n = 10–12/experimental group). C Graphical representation of the individual values of the discrimination ratio of the animals in the NORT. Values were calculated by using the following formula: discrimination ratio = (time spent exploring the new object − time spent exploring the known object)/total exploration time. Any animals that showed lower than average activity or any divergent preference for one of the identical objects in the training had their results discarded from the analysis (n = 10–12/experimental group)
