Summary: The aim of the research was to investigate feed nutrient digestion and slaughter indicators of broiler chickens fed a probiotic supplement based on lactic acid bacteria. The experiment lasted for 42 days. Four groups of one-day-old broiler chickens of the Ross-308 cross were selected by the method of analogous groups, each group contained 50 birds. Broilers were kept in group cages considering all zoohygienic requirements. The control group consumed a basic diet (BD), i.e., a complete feed. The experimental groups were additionally fed different doses of a probiotic supplement (by percentage mass of feed). The broiler chickens fed the probiotic supplement had increased digestibility of dry matter, protein, fibre and nitrogen-free extractives (NFE) compared with the control group. The application of probiotic supplement in broiler feeding increases the availability of essential amino acids, i.e. lysine, histidine, arginine, threonine, valine, methionine, isoleucine compared with the control. The absorption of Ca, P, Mg, and Mn increased with the probiotic supplement. The probiotic supplement application in the diet of broiler chickens increased the pre-slaughter live weight by 16.7%, the un-gutted body weight by 15.0% and gutted body weight by 17.3%. Probiotic supplement had a positive effect on the digestibility of feed nutrients, increased the absorption of amino acids and minerals in the body broiler chickens.
