Резюме: In Agricultural institute - Shumen was carried out a scientific-economic experiment with a total number of 20 pigs from Danube white breed, divided into two groups with 10 pigs in each. The experiment has started in 36.857-37.000 kg live weight and has ended in 103.710-106.286 kg live weight. The aim of the present study was to establish the effect of high level of fibers from the use of lucerne meal on the productivity, carcass traits and physico-chemical composition of m. long. dorsi in fattening pigs.
It was established that by adding 2.5% lucerne meal in the compound feed for Danube white fattening pigs from 36 kg to 80 kg live weight the gain increased insignificantly with 10,06% and has improved the feed conversion ratio with about 10,27% but didn’t influence on the productivity during the finishing period (from 76 kg to 106 kg live weight).
The use of 2.5% lucerne meal in the compound feed for fattening pigs didn’t effect on the values of the separate carcass and quality traits of m. Long. Dorsi. There are higher values of traits like fat with 8,95% (insignificantly) and calcium contain with 30.91 % (P≤0.05) in m. Long. Dorsi in pigs from the experimental group.
