Simple Summary: On the basis of the extensive literature, two main strategies have been used to
manipulate intestinal microbial composition and selectively stimulate the growth and activity of
certain species, these being the administration of either prebiotics or food supplements containing
living bacteria such as probiotics. Several animal studies have indicated that certain probiotics,
including Lactobacilli and Bifidobacteria, can suppress body weight gain in rodents, while some
probiotics strains have little effect or promote weight gain. The potential anti-obesity effect of
probiotics seems to depend on the strains used and the underlying mechanisms, leading to their
effects remaining not fully understood. It is in this context that this study was designed to investigate
the potential of two probiotics strains, these being Bifidobacterium animalis subsp. lactis BB-12® and
Lactobacillus plantarum 299v® in rabbits, whereby obesity and metabolic syndrome was first induced
in a first experiment, and the animals were then used in a second experiment to test the hypothesis
of probiotics effect on biochemical and morphometric parameters. The model of obesity induced
by giving a “cafeteria” diet for 14 weeks in this trial demonstrated a change in the biochemical and
morphometric parameters investigated in the ITELV2006 rabbit strain. This study revealed that B.
animalis subsp. lactis BB-12 and L. plantarum 299v strains could exert beneficial effects in reducing the
incidence of obesity and metabolic syndrome in the ITELV2006 rabbit strain.
Abstract: This study aimed first to develop an experimental model of obesity and metabolic syndrome
over 14 weeks using a diet called “cafeteria”, which is a high-fat diet, to evaluate its consequences on
the biochemical and morphometric parameters in ITELV2006 strain rabbits. Second, the trial aimed to
evaluate the effect of two strains of probiotics, these being Bifidobacterium animalis subsp. lactis BB-12®
and Lactobacillus plantarum 299v®, on the obesity and MetS induced during the first experiment.
Overall, the results of the “cafeteria” diet demonstrated significant changes in numerous biochemical
and morphometric parameters, reproducing obesity and the main clinical manifestations of the
metabolic syndrome in humans. The administration of the two probiotic strains demonstrated an
impact on certain parameters of obesity and induced MetS. This study makes it possible to conclude
that probiotics could be useful in the treatment of obesity and metabolic syndrome of rabbits, but in a
dependent manner. Furthermore, this study evidenced the importance of selecting specific probiotic
strains and dosages to achieve desirable results on rabbits or other species.
