Analysis of variance (with room, parity, sow diet, and their interactions as effects; the interactions were non-significant, therefore, they were removed from the model.
Non-parametric test (Kruskal-Wallis) with sow diet as effect.
Analysis of variance (with room, parity, sow diet, and their interactions as effects; number of piglets at the beginning of the period was used as covariate); the interactions were non-significant, therefore, they were removed from the model.
