EFFECT FROM THE USE OF LUCERNE MEAL ON THE PRODUCTIVITY OF WEANING PIGS

R Nedeva, D. Kanev

Abstract: In the Agricultural Institute, Shumen was carried out a scientific and economic experience with a total number of 54 weaning meal and female pigs divided into 3 groups with 18 pigs in each. The experience has started immediately after pig weaning of 12.8 - 13.9 kg live weight and has ended in 38.6-43.3 kg. Pigs from Ist (control) group were fed with starter compound feed containing 19.11% of crude protein, 1.03% lysine and 4.58% crude fibers. The level of the fibers in IInd (experimental) group was increased by adding 5% lucerne meal in the compound feed. Pigs from IIIrd (experimental) group received the same compound feed to which Hostazym suis was added in a dose of 175 g / tone. It was established that the increase of the fibers' level (from 4.58% to 5.61%) by adding 5% lucerne meal in the compound feed for Danube White growing pigs from 12.8 - 13.9 kg to 38.6 - 43.3 kg live weight leads to an insignificant gain decrease with 12% and an increase of the feed conversion per kg gain
with 12 - 13%. The addition of Hostazym suis in the compound feed by adding 5% lucerne meal has improved in a statistically insignificant way the intensity of the growth and the feed utilization with about 7%. Higher levels fibers rations from lucerne meal didn't exercise statistically insignificant influence on the pigs'
behavior (the motive activity).
