The diploma thesis is aimed on verification of a posibility of using blue lupin as a proteinic fodder in pig fattening and is based on a two-phase experiment that corresponds with two-phase fattening. In the first (from 22 to 41 kg) and second (from 41 to 119 kg) phase, the control group was fed with a mixture based on extracted soybean meal, the treatment group was fed with a mix containing 10 % (first phase) and 13 % (second phase) of blue lupin. The observed statistical indicators were average daily gain in weight, average daily fodder consumption and average nutrients conversion. The first phase of the experiment resulted in growth of all of the observed indicators. The treatment group showed a nutrients conversion increased by 150 g and average daily gain in weight increased by 200 g in comparison with the control group. In the second phase of the experiment (during first 31 days), the observed indicators of the treatment group showed a drop (additional 350 g of mixture were needed for 1 kg gain in weight compared to the control group, the average daily gain was lower by 130 g). Subsequently a gradual stabilization followed, resulting in a final difference of 160 g in nutritions conversion and 50 g of average daily gain in favor of the control group. The economical effect of 34.5 CZK per fattened pig was found despite of worse indicator values in the second phase. Blue lupin has potential to be used as a substitute for soybean, but only when assuming self-sufficiency, because its availability is relatively low when compared to soybean.
