ALVARADO-LOZA, Erika et al. The 2% of agave inulin level in the rabbit feed affects positively the digestibility and gut microbia. Abanico vet [online]. 2017, vol.7, n.3, pp.55-62. ISSN 2448-6132.  https://doi.org/10.21929/abavet2017.73.6.

Oligosaccharides present in feed act as microflora modulator and nondigestible fiber source. Agave azul tequilana Weber is a plant that is primarily used to produce tequila and as a source of the fructo-oligosaccharide inulin. Eighteen male rabbits nourished with commercial feed were used to assess three levels (0, 1, or 2%) of agave inulin addition, and its impact on digestibility and microbial population of the intestine. The addition of the agave inulin reduced the intake and increased the apparent digestibility of nutrients (p < 0.05), except for the energy digestion (p > 0.05). Also, water daily intake was significantly reduced (p < 0.05). On the other hand, fecal E. coli count (UFC/g) was drastically reduced with the addition of the agave inulin in the feed. In conclusion, use of 2% of agave inulin in feed affects positively the rabbit digestibility and reduces the gut microbial population.
