W-SBM, wheat/soybean meal; W-RSM, wheat/rapeseed meal; R-SBM, rye/soybean meal; R-RSM, rye/rapeseed meal; SEM, standard error of the mean; CER, cereal; PM, protein meal. 1 Data are presented as means (n = 11); p-values indicate effects of the factors cereal (CER), protein meal (PM) and their interaction (CER * PM). 2 W-RSM: n = 10 (DNA-extract not amplifiable). a, b Values within a row with different superscripts differ significantly at p ≤ 0.05 (Tukey test).
