Abstract: The purpose of the present study was to evaluate the effect of soya replacement (50 or 100%) with whole (WL) or dehulled seeds (DL) of white lupine cv. Butan in the diets for market pigs. The experiment was performed on 50 pigs in equal numbers of barrows and gilts with the initial mean body weight (BW) of 18.3 ± 2.1 kg, fed isonitrogenous and isoenergetic diets for 100 days. In the experimental starter pigs (18 to 35 kg BW), the mean daily body weight gain (BWG) was 0.61 to 0.64 kg and was insignificantly lower by 1.5 to 6.2% in comparison with the pigs fed the control soya diet (SBM). The diet intake was also lower by 5.4 to 6.8% and could result from a higher content of crude fibre. In the grower and finisher diets, no side effect of high lupine levels on the feed intake was evident. The intake of DL diets was higher in comparison with the soya diet. The feed efficiency of the finisher diets was insignificantly higher (P > 0.05) for experimental diets (WL 50, WL 100, DL 100) in contrast to the control diet. The differences among diets containing WL or DL seeds were insignificant. During the experiment, no adverse effect of lupine on the health of pigs was observed and no significant differences in the parameters of market pig meat, nutrition quality of meat and sensory analysis were detected. The inclusion of lupine in diets resulted in a significantly lower n-6/n-3 ratio of polyunsaturated fatty acids (P < 0.01) in meat lipids (5.15 to 5.33) in comparison with soya (8.75). It follows from the obtained results that the tested lupine variety seeds are a source of high-quality protein that can be an alternative to soya in the diets for market pigs.
