This study aimed to investigate the effects of modified-dietary fiber from cassava pulp (M-DFCP), mostly classified as insoluble dietary fiber (IDF), as a feed supplement on productive performance, nutrient digestibility, weight of digestive organs, abdominal fat storage, and cholesterol in meat and blood of broiler chickens. A total of 336 one-day-old male broiler chickens (Ross 308) were allocated to 4 groups in 7 replicate pens with 12 chicks each, based on a completely randomized design. Four dietary treatments composed of control and 3 M-DFCP inclusion levels: 0.5, 1.0, and 1.5%. The results showed that M-DFCP showed no negative effects on growth performance in broiler chickens. The inclusion of M-DFCP in diets at 1.0 to 1.5% had positive effects on increased gizzard weight, reduced gizzard pH, and reduced abdominal fat. The M-DFCP at 1.0% can also increase nutrient digestibility (dry matter, organic matter, and ether extract). In addition, the supplementation of M-DFCP at 1.0 to 1.5% in diets represented lower cholesterol in serum, breast and thigh meats, and liver of broiler chickens. In conclusion, these results indicate that M-DFCP can be used as an IDF source in broiler diets. The inclusion of 1.0% M-DFCP in broiler diet has positive effects on enhancing gizzard function, improving nutrient digestibility, and reducing abdominal fat and cholesterol in chicken meat, blood, and liver.

本研究旨在研究木薯粕（M-DFCP）中改性膳食纤维的影响，主要归类为不溶性膳食纤维（IDF）。），作为肉鸡生产性能，营养物质消化率，消化器官重量，腹部脂肪存储和胆固醇的饲料补充。基于完全随机设计，将总共336只1日龄雄性肉鸡（罗斯308）分配到7组重复笔中的4组，每组12只。四种饮食疗法由对照组和3种M-DFCP包含水平组成：0.5％，1.0％和1.5％。结果表明，M-DFCP对肉鸡的生长性能没有负面影响。日粮中添加1.0-1.5％的M-DFCP对增加izz的体重，降低izz的pH值和减少腹部脂肪具有积极作用。含量为1.0％的M-DFCP也可以提高养分消化率（干物质，有机物质和乙醚提取物）。此外，以1.0：1的比例补充了M-DFCP。日粮中的5％代表血清，胸肉和大腿肉以及肉鸡肝脏中的胆固醇降低。总之，这些结果表明，M-DFCP可用作肉鸡日粮中的IDF来源。在肉鸡日粮中添加1.0％M-DFCP对增强g功能，改善营养物质消化率以及减少鸡肉，血液和肝脏中的腹部脂肪和胆固醇具有积极作用。
