Effectiveness of the use of probiotics in the diet of broiler chickens

The aim of the experiment was to research the productivity and carcass characteristics of broiler chickens receiving a probiotic feed supplement. The probiotics added to the diet of broiler chickens were shown to increase live weight by 11,9%, average daily gains by 12,1%, and total weight gain by 12,2%, reducing feed consumption per kg increase by 8,9% compared with the control. Consumption of the probiotic feed supplement increased the pre-slaughter live weight by 12,0% and the gutted carcass weight by 13,3% relative to the control
