Zeolite, as a natural mineral, could be a good additive for ducks, in line with pro-environmental trends. The study aimed to evaluate zeolite additives in feed for broiler ducks of both sexes on production results, meat quality, and the strength of the jejunum, tibia, and femur. The experiment used 200 Cherry Valley ducks, divided into a control group of males (CM) and females (CF) and an experimental group of males (ZM) and females (ZF). In the control groups, a commercial diet was used. In the experimental groups, 1% zeolite was added. The ZM group demonstrated higher body weight and weight gain than the CM group. Zeolite reduced the feed conversion ratio. A higher liver weight was found in the experimental group (ZM). Notably, zeolite influenced the weight of male pectoral muscles. Higher water loss in the pectoral muscles and higher protein content in the leg muscles were found in the same group. Females had a higher weight of neck and wings with skin. Female pectoral muscles had lower protein and water content. Zeolite in feed at a 1% level for broiler ducks could be recommended as a natural additive that positively affects the ducks' production results concerning good quality meat.
沸石作为一种天然矿物，可以作为鸭子的良好添加剂，符合环保趋势。本研究旨在评估沸石添加剂对雌雄肉鸭生产性能、肉质和空肠、胫骨和股骨强度的影响。实验使用了 200 只樱桃谷鸭，分为雄性对照组（CM）和雌性对照组（CF）以及雄性实验组（ZM）和雌性实验组（ZF）。在对照组中，使用商业饮食。在实验组中，添加了 1%的沸石。ZM 组的体重和体重增加均高于 CM 组。沸石降低了饲料转化率。实验组（ZM）的肝脏重量更高。值得注意的是，沸石影响了雄性胸肌的重量。同一组的胸肌失水率更高，腿部肌肉的蛋白质含量更高。雌性的颈部和翅膀带皮的重量更高。雌性胸肌的蛋白质和水分含量较低。建议在肉鸭饲料中添加 1%的沸石作为一种天然添加剂，对鸭的生产性能和优质肉有积极影响。
