Dietary Fermented Rapeseed Meal During the Grower Period Affects Growth Performance, Intestinal Health, and Antioxidant Status in <i>Sansui</i> Ducks by Yulong Feng, Meijuan Li, Yuxi Lu, Chengcheng Tian, Yu Zhao, Jianwei Li, Zhiguo Wen, Yongwen Zhu

“…In conclusion, 15 or 20% dietary FRSM (3.25 or 4.34 µmol GLS/g diet) during the grower period in <i>Sansui</i> ducks decreased feed efficiency, disrupted hepatic antioxidant balance, and impaired intestinal morphology and structure. The FRSM inclusion of ≥15% (3.25 µmol glucosinolates/g) impaired feed efficiency and antioxidant activity, while the 20% FRSM (4.34 µmol glucosinolates/g) induced intestinal damage in the growing <i>Sansui</i> ducks.…”
