EFFECTIVENESS OF USING DIETS CONTAINING YELLOW LUPINE CULTIVAR MISTER IN GROWING PIGS

The paper aimed at evaluating the effect of yellow lupine used in feed rations for growing pigs on the animals’ growth parameters and slaughter value. The experiment involved 40 pigs [(PLW×PL)×Duroc] which were divided into 2 groups: control (C) and experimental (E). The sole source of protein in rations fed to the control pigs was soybean meal, whereas rations for the experimental pigs contained respectively 10, 15 and 20% of lupine in the corresponding periods: grower, fattener I and II. The inclusion of lupine in feed rations for weaner pigs and fatteners during period I did not affect the production performance, whereas for fatteners during period II it did increase (P ≤ 0.05) daily weight gain values. Slaughter value was similar for the compared groups of pigs (P > 0.05). To sum up, an inclusion of 10, 15 and 20% lupine in feed rations for pigs can be recommended due to a significant increase in the final body weight and simultaneously increased feed conversion effectiveness. In addition, the feeding pattern did not affect the muscularity and fattening grade of pigs.
