Azione benefica dei FOS e MOS sull'intestino di cani sani
L’integrazione di fruttooligosaccaridi and Mannanoligosaccaridi influenza la funzione immunitaria, la digeribilità dei nutrienti nel tratto ileale, le popolazioni microbiche e le concentrazioni dei cataboliti proteici nell’intestino crasso dei cani.

L’obbiettivo di questo studio è stato di valutare se l’integrazione di fruttoligosaccaridi (FOS) e di mannanoligosaccaridi (MOS) influenzano i parametri dell’intestino sano nei cani.
Abstract: Adult female dogs (n = 4) surgically fitted with ileal cannulas were fed a dry, extruded, kibble diet twice daily. At each feeding, the following treatments were administered: 1) Control (no FOS or MOS); 2) 1 g FOS; 3) 1 g MOS; or 4) 1 g FOS + 1 g MOS. Fecal, ileal and blood samples were collected during the last 4 d of each 14-d period to measure protein catabolite concentrations, microbial populations, immune characteristics and nutrient digestibilities. Treatment means were compared using preplanned orthogonal contrasts. Dogs supplemented with MOS had lower (P = 0.05) fecal total aerobes and tended to have greater (P = 0.13) Lactobacillus populations. Ileal immunoglobulin (Ig) A concentrations were greater (P = 0.05) in dogs supplemented with FOS + MOS vs. control. Lymphocytes (% of total white blood cells) were greater (P < 0.05) in dogs supplemented with MOS. Serum IgA concentrations also tended (P = 0.13) to be greater in dogs supplemented with MOS. Dogs supplemented with FOS and FOS + MOS had lower (P < 0.05) fecal total indole and phenol concentrations. Dogs supplemented with MOS tended to have lower ileal DM (P = 0.149) and OM (P = 0.146) digestibilities vs. control.
I risultati di questo studio suggeriscono che l’integrazione alimentare di FOS e MOS può avere effetti benefici sulla salute del colon e dello stato immunitario dei cani.
