A three-month feeding trial was conducted to investigate the effects of faba bean (Vicia faba L.) on growth performance, intramuscular collagen content, muscle cellularity and fillet texture of Yellow River carp, Cyprinus carpio haematopterus. Carps with an initial weight 500 ± 20 g were randomly divided into two treatments: commercial feed group (CFG) and faba bean group (FBG). Compared to CFG, the results indicated that carps fed with faba bean had poor growth performance, higher intramuscular collagen content, smaller fiber diameter and wider intermyofibrillar space. However, the fiber density was not influenced (P > 0.05). The faba bean components showed lower crude protein and amino acid imbalance, especially, the deficiency in the sulfuric amino acid. The raw-fillet and cooked-fillet texture of FBG were both significantly greater than that of CFG (P < 0.05). Muscle fiber diameter and cooked-fillet texture showed significant negative correlation (P < 0.05), significant positive correlation between intramuscular collagen content and cooked-fillet texture (P < 0.05), and no significant correlation between muscle fiber density and fillet texture (P> 0.05). In summary, faba bean could improve the fillet quality for Yellow River carp. These findings would contribute to define the optimal nutritional conditions of pond culture to improve the flesh quality of Cyprinus carpio haematopterus.

为期三个月馈送试验以调查蚕豆（的效果蚕豆L.）生长性能，肌肉内胶原蛋白的含量，肌肉细胞构成和黄河鲤鱼，圆角的质地鲤鱼haematopterus。初始重量为500±20 g的鲤鱼随机分为两种处理：商品饲料组（CFG）和蚕豆组（FBG）。结果表明，与蚕豆相比，饲喂蚕豆的鲤鱼生长性能较差，肌内胶原含量较高，纤维直径较小，肌原纤维间间隙较大。但是，纤维密度没有受到影响（P> 0.05）。蚕豆成分显示出较低的粗蛋白和氨基酸失衡，特别是硫酸氨基酸缺乏。FBG的生鱼片和熟鱼片质地均显着大于CFG（P  <0.05）。肌纤维直径和鱼片质地呈显着负相关（P  <0.05），肌内胶原含量和鱼片质地呈显着正相关（P  <0.05），肌纤维密度和鱼片质地之间无显着相关（P> 0.05）。总之，蚕豆可以改善黄河鲤鱼的鱼片质量。这些发现将有助于确定池塘养殖的最佳营养条件，以改善鲤鱼的肉质。
