The main aim of this work was to compare the stimulatory effect of the probiotic BioPlus 2B with that of the antibiotic Avilamycin on the growth and feed conversion in broiler chickens. The growth experiment was performed with one-day-old sexed female and male ROSS 308 hybrid chickens (240 females and 240 males) placed in 24 cages. They were fed the starter diet from Day 1 to Day 14, followed by the grower from Day 15 to Day 35 and the finisher in a loose form from Day 36 to Day 42. Diets and water were available ad libitum. The chickens were slaughtered at the end of the experiment (Day 42) to determine the slaughter yield and the content of inner fat. The supplementation with BioPlus 2B led to an increase in body weight by 4-5% (P less than 0.01) and to an improvement in feed conversion efficiency by 4-5% (P less than 0.01). Mean slaughter yields were higher (P less than 0.01) in chickens fed diets containing probiotic and antibiotic products than in control animals. The weight of inner fat did not differ significantly.
