Comparison regarding general health and behaviour between pups nursed by wild-type dams and pups nursed by α-casein deficient dams.

P-values of parameters without significant differences between group 1 (G1: wild-type pups nursed by wild-type dams) and 2 (G2: wild-type pups nursed by α-casein deficient dams; P-value G1 vs. G2) and group 1 and 3 (G3: heterozygous pups nursed by wild-type dams; P-value G1 vs. G3) at 8 weeks of age (Fisher's exact test and *Mann-Whitney-U test). Constant values indicate that all animals in the groups compared had the same, normal, score.
