摘要： The aim was to investigate effects of various proportions (0 to 20%) of fermented rapeseed meal (FRSM) on performance, intestinal health, and antioxidant status in Sansui ducks (Sansui Sheldrake ducks). A total of 350 male ducklings, 15 d old, were allocated into five dietary treatments with seven replicate pens of 10 birds per pen. The starter diets had 0, 5, 10, 15, or 20% FRSM that contained 0, 1.08, 2.17, 3.25, or 4.34 mu mol glucosinolates (GLS/g of complete feed, respectively, fed from d 15 to d 35. The average daily feed intake (ADFI) and feed conversion ratio (FCR) from d 15 to 35 increased linearly with the dietary FRSM inclusion, with the ducks fed 15 or 20% FRSM diets having higher (p < 0.05) ADFIs and FCRs than the ducks fed 0% FRSM. The dietary FRSM inclusion levels of up to 15% were accompanied by decreased catalase (CAT) and antioxidant capacity (AOC) activities in the livers and jejunum of the ducks at d 35. In addition, the 20% FRSM (4.34 mol GLS/g diet) decreased the villus height, crypt depth, muscular thickness, and goblet cell counts in the jejunum and ileum. In conclusion, 15 or 20% dietary FRSM (3.25 or 4.34 mu mol GLS/g diet) during the grower period in Sansui ducks decreased feed efficiency, disrupted hepatic antioxidant balance, and impaired intestinal morphology and structure. The FRSM inclusion of >= 15% (3.25 mu mol glucosinolates/g) impaired feed efficiency and antioxidant activity, while the 20% FRSM (4.34 mu mol glucosinolates/g) induced intestinal damage in the growing Sansui ducks.
