Using feed additives as a way to improve growth performance in weaned piglets

A combined probiotic preparation of 1x109 CFU/kg, Enterococcus faecium DSM 7134 and 2x109 CFU/kg Saccharomyces cerevisiae E 1703 was supplemented to a basal diet with 1g/kg feed. The effects on growth performance, on thirty weaned piglets (28 days) were studied for six weeks experimental period. At the end of experimental period the supplementation of combined probiotic improved slightly Daily Weight Gain (DWG) g/day (2.7%) and Feed Conversion Ratio (FCR), kg feed/kg weight gain (4.4%). Because of the high coefficient of variations the differences were not significant. Based on the achieved results in the present investigations, it could be concluded that the utilization of probiotis led to an improvement of the production parameters in pigs, especially under the extensive farm conditions.
