Treatment of adult mice with a mixture of three lactobacilli strains resulted in an increase in body weight. Ten-week-old male mice were treated with either vehicle (veh) or a mixture of three lactobacilli (L. Mix) for 6 weeks, starting 2 weeks before orchiectomy (orx) or sham surgery. Study protocol (A). Body weight (BW) curve (B). Values are given as mean ± s.e.m. (n = 13–15). Body weight at the end of study (C). Symbols in the scatter plots represent individual mice and the bars indicate mean ± s.e.m. The overall effects of treatment (Veh/L. Mix), surgical procedure (sham/orx) and their interaction were calculated using two-way ANOVA, NS, not significant.
