| Abstract: | Herein, we assessed the impact of dietary addition of konjac mannanoligosaccharide (MOS) on the growth, intestinal morphology, serum immune status, and oxidative status in Partridge Shank chickens. For the experiment, one-day-old chicks (n=192) were randomized into six replicates (n=8/replicate) and fed four different diets: a basal diet containing 0 (Control group), 0.5, 1, or 1.5 g MOS per kg of diet (g/kg) for 50 d. Relative to the control, the group fed 0.5 g/kg MOS decreased feed consumption from 22nd to 50th d and 1st to 50th d (P<0.05). By adding MOS, the height of the intestinal villus and the villus height to crypt depth ratio were increased (P<0.05); 1.5 g/kg MOS was the best dosage for these parameters. Jejunal and ileal goblet cell density increased following MOS supplementation at 21 d (P<0.01) and 50 d in the jejunum (P<0.05), respectively. Moreover, adding MOS to the diet increased the contents of IgA and IgM at 21 d (P<0.05) and total antioxidant capacity (P<0.05) at 50 d in the serum but decreased malondialdehyde content (P<0.01) at 21 d in the group fed 0.5 and 1.5 g/kg MOS. The findings suggested that MOS supplementation could affect feed consumption, intestinal health, serous immunity, and antioxidant capacity of Partridge Shank chickens. |
