Abstract: A scientific experiment assigning a total number of 27 growing male and female pigs, allotted into 3 groups of 9 pigs each, was carried out in Agricultural Institute, Shumen. The starting live weight was 37.9-39.0 kg, and the finishing – 100 kg. The experiment was conducted in two sub-periods – the first to 62.7-67.1 kg, and the second – to 100 kg live weight. The pigs from the control group were fed the basal compound feed (containing 17.15-15.12% protein and 0.84-0.72% lysine, respectively from 30 to 80 kg and from 80 to 100 kg live weight). The pigs from group ІІ (experimental) were fed 95% of the feed of group І and 5 % lucerne meal. The pigs from group III (experimental) received the same compound feed to which Hostazym suis enzyme product was added of a dose of 175 g/ton. It was established that the inclusion of 5%
lucerne meal in the compound feed for Danube White fattening pigs of live weight from 37.9-39.8 to 99.5-103.25 kg leads to insignificant gain increase by 5.7-11.4% and to improved utilization of feed by 4.6-11.0 %. The inclusion of Hostazym suis in the compound feed containing 5% lucerne meal has not improved with statistical ignificance growth rate and feed utilization.
