Feed preference (Experiment I) and growth performance tests (Experiment II) were carried out on growing pigs fed on diets differing in yellow lupin levels. In Experiment I , dietary choices were determined using the single stimulus method on 12 individually kept young pigs. In Experiment II, basic growth parameters were studied in 36 young pigs. Three diets were used: control (1), with soyabean meal (SBM) as the only high-protein component, and experimental diets in which lupin protein substituted for 75 (diet 2) or 100% (diet 3) of SBM protein. The lupin content in diets 2 and 3 was 19 and 25%, respectively. During a 28-day feed preference test, daily intake of the three diets amounted to 760, 736 and 700 g, respectively; the differences are statistically significant. The average daily weight gains and feed intake were similar, while the best feed conversion ratio was in pigs fed on the diet with 19% yellow lupin seed meal.
