Popis:	The supplemental values of prepress solvent-extracted rapeseed meal (RSM) from Brassica campestris cv. Span seed, solvent-extracted peanut meal (PNM) and soybean meal (SBM) with or without added lysine were compared using barley–wheat-based diets. Pietrain and crossbred-sired barrows and gilts and uncastrated male and female rats were the test species. For rate of gain with pigs, SBM, RSM and PNM ranked in that order, while for rats, PNM and SBM were similar with RSM being inferior. Partial substitution of RSM for 50 or 75% of PNM in diets of pigs tended to improve performance. Lysine addition to the PNM-supplemented diet did not significantly enhance food consumption, gain or efficiency of food conversion of rats, but there was a trend toward improvement of these criteria with pigs. No significant treatment, sex or breed differences were observed in energy digestibility or in metabolizable energy. In N retention as a percentage of intake, gilts were superior (P
