摘要: This study was to investigate the effect of oxidized wheat gluten (OG) on growth performance, gut morphology and its oxidative states of broilers. One hundred and eighty-day-old male broilers (10 chicks/pen) were randomly allocated into three dietary treatments: control diet (CON), diet with 8% wheat gluten (WG) and diet with 8% OG with six pens/treatment. Body weight (BW) (21 and 35days) and average daily gain (ADG) (1-21days and 22-35days) decreased (p<.05) and feed conversion ratio (FCR) (1-21days and 22-35days) increased (p<.05) in OG treatment. Feed intake (FI) decreased (p<.05) in WG and OG treatments during 22-35days. However, FI was not influenced by dietary treatments during 1-21days (p>.05). The OG-fed broilers had a lower faecal pH value (p<.05) and higher faecal moisture content (p<05) at 14, 21, 28 and 35days. Villus height, crypt depth and V/C value were not different (p>.05) among treatments at 21 and 35days. Lipid peroxidation (LPO) (21 and 35days) and malondialdehyde (MDA) (35days) content in crop of OG treatment increased (p<.05). Oxidized glutathione (GSSG) (21days), LPO (21 and 35days) and MDA (21 and 35days) content in ileum of OG treatment increased (p<.05). The reduced glutathione/oxidized glutathione (GSH/GSSG) (21days) and (GSH) (35days) in ileum of OG treatment decreased (p<.05). The present findings indicate that OG might be a stressor for broiler gut, which could induce oxidative stress both in crop and in ileum, and the diarrhoea as well. The growth performance of broiler was consequently depressed.
