Comparison of efficacy of lactic acid bacteria complex and Enterococcus faecium DSM 7134 in weanling pigs

ABSTRACTWe conducted this study to compare the effects of lactic acid bacteria complex (L. casei, L. rhamnosus, L. lactis, L. plantarum, S. thermophilus, and B. longum) and Enterococcus faecium DSM 7134 in weanling pigs. A total of 120 weanling pigs (24-day-old) were used in a 5-week feeding trial. Pigs were allotted into three dietary treatments: CON, basal diet; LA, CON + 0.1% lactic acid bacteria complex; EF, and CON + 0.1% E. faecium DSM 7134. From days 0 to 14, days 15 to 35, and the overall period, average daily gain was higher (P < .05) in EF than that in CON. Higher gain:feed ratio was also observed in EF compared with CON during the overall period. The apparent total tract digestibility of dry matter, nitrogen, and gross energy was greater (P < .05) in LA and EF compared with CON on days 14 and 35. Faecal Lactobacillus counts were increased (P < .05) and faecal pH was decreased in LA and EF compared with CON on days 14 and 35. Results of the current study indicated that E.faecium DSM 7134 has bet...
