The average weight gain of piglets in the experiment, kgThus, at the early stages of the piglets’ development the introduction ofprobiotic in the fodder was the best at the level 2.0 kg/t in the second experimentalgroup; then the same level of supplement was more efficient at the end of theexperiment in the LE 4 experimental group.Table 5 Average weight gain of pigletsThe average weight of piglets, kgLot at the beginning of theexperimentat the end of the II nd periodof the experimentat the end of theexperimentLM 9.86 ± 0.069 47.92 ± 1.819 99.99 ± 1.986LЕ1 9.95 ± 0.070 39.83 ± 1.775 91.36 ± 3.640LЕ2 9.79 ± 0.083 44.70 ± 1.702 93.64 ± 1.678LЕ3 9.83 ± 0.075 44.06 ± 2.260 100.25 ± 1.917The live weight of the piglets in group LE 2 and LE 3 which got probioticsupplement at the level of 1.5-1.0 and 2.0-1.5 g/t, according to the stages of theexperiment, was a little higher – by 0.41 % (100.40 kg) – than in the control group(LM); in group LE 1 the piglets weight was 91.36 during the experiment, while ingroup LE 2 the weight was 93.64 kg, that is much lower than the weight of thepiglets in the control group.During the trial the average daily weight gain was of 0.609; 0.550; 0.567and 0.611 kg/head respectively in LM and LE 1 , LE 2 , LE 3 experimental groups.123
