Two performance trials with fattening pigs was conducted on Lithuanian agricultural farms. The objec-tive of the study was to determine the effect of a probiotic product containing Enterococcus faecium (trade name "Bon-vital") on the fattening performance and carcass characteristics of pigs as well as on meat quality under production con-ditions. Each trial comprised two groups, a control group (I) and an experimental group (II). Animals of group II were fed a diet supplemented with the probiotic product Bonvital (Enterococcus faecium DSM 7134, 0.3x109 CFU/kg feed). Group I animals received the same diet, but without the addition of the probiotic. Diet composition matched the nutrient requirements of high-performance pigs. Both trials went according to the plan. There were no health problems. Nevertheless, the performance levels achieved inboth trials differed distinctly (trial 1: average daily gain - 688 g, 3.49 kg feed/kg gain, trial 2: average daily gain - 870 g, 2.4 kg feed/kg gain, in control groups). A performance enhancing effect of Bonvital was observed inboth trials, leading to an increase in daily gains (3% in trial 1 and 1.5% in trial 2) and an improvement in the feed conversion ratio (3% in trial 2). The above effect was statistically significant (p<0.05) and numerical (p>0.05). There were small differences between control and experimental animals with respect to carcass characteristics and meat quality.
