Abstract: Two scientific experiments with Danube White pigs were carried out in Agricultural Institute, Shumen. The first was carried out with 48 number growing pigs, allotted into 3 groups of 16 pigs in each. Pigs in this experiment were rearing in group pens.The starting live weight was 12.20 -12.60 kg , and the finishing- 30.90 – 33.70 kg. The second trial was carried out with 20 pigs from the first trial, allotted into 2 groups of 10 pigs in each. The second experiment was started at 32.833 – 33.400 kg and finished at 110 kg live weight. In the fist trial 2.5% and 5.0% lucerne meal was included in ration of ІІ and ІІІ groups, and in second trial 2.5% lucerne meal was used in compound feed of experimental group. It was establish that including of 2.5 % lucerne meal in compound feed for Danube White growing pigs from 12 to 33 kg live weight leads to significant gain increasingby 13% and improved utilization of feed by 8%. Using of 2.5% lucerne meal in compound feed for Danube White fattening pigs from 33 kg to 110 kg live weight did not influenced on intensity growth and feed utilization. Adding of lucerne meal in compound feed for fattening pigs did not significant influence on m. longisimus area and % lean meat and decreased backfat in point x2 .
