Feed anƟbioƟcs affect negaƟvely poultry’ gut organisms causing reducƟon of natural resistance to different dis-
eases and consequently low producƟvity. Development of biologically acƟve addiƟves is one of the approaches
in overcoming this problem which allow neutralizing the anƟbioƟc’s effect or even subsƟtuƟng them in the poul-
try’s diet. In 2010 on the base of the poultry farm “Zvenigovskaya” (The republic of Mariy El) the effecƟveness
of “Laktofit” and “Laktofleks” obtained in Volgograd Research Technological InsƟtute of Meat and Dairy Farming
and Processing of Livestock Products was studied. Three groups each consisƟng of 50 broilers grown for the peri-
od of 40 days were formed. BAD applicaƟon provided the average weight gain of 2.6…8.9 % compared to the ref-
erence group; feed input per 1 kg of gain reducing from 1.82 kg to 1.76…1.66 kg. Haematology test panel demon-
strated erythrocytes’ and leukocytes’ content increase in chickens’ blood indicaƟng the rise of their natural resis-
tance by 2…4 % on comparison to the reference group. BeƩer resistance, producƟvity and meat quality led to the
primecost reducƟon of 1 kg of products and sale price increase. “Laktofit” and “Laktofleks” gave the benefit of
2886.26 and 4558.17 rubles per 1000 of broilers respecƟvely.
Keywords: biologically acƟve addiƟve, “Laktofit”, “Laktofleks”, feeding of broiler chicken, producƟvity of broiler
chicken, meat quality of broiler chicken, economical efficiency of broiler chicken’ raising.
