The production of cellulose nanofibers promotes the utilization of plant residues that are generated in agro-industries during food processing. The utilization of these plant by-products reduces environmental contamination. Cellulose nanofibers are used in several sectors, including the drug, food, and animal nutrition industries. Many sources of nanofibers used in animal diets can be used as potential fiber substitutes after being processed to improve efficiency. For instance, including nanometric particles of plant fibers (<100 nm) in animal feed may provide excellent physical properties such as high reactivity, a large surface area, and improved nutrient absorption from the diet. Nanotechnology improves the characteristics of fibers that are important for gastrointestinal transit and their utilization as energy sources and substrates for microbial fermentation in the digestive tract of animals. Nanofibers can improve the synthesis of volatile fatty acids and the blood lipid profile, with positive effects on the intestinal health of animals. Moreover, and studies have demonstrated promising effects in reducing blood glucose levels without toxic effects on the body. Supplying nanofibers in the diet improve animal performance, increase productivity, and work toward a more sustainable economic development of agribusinesses. The quality of animal products such as meat, milk, and eggs is also reported to be improved with the inclusion of nanominerals in the feed. Overall, the application of nanotechnology to harness the by-products of agro-industries can increase economic viability and sustainability in animal production systems. Therefore, this review presents a current survey on the main research and advances in the utilization of nanotechnology, focusing on cellulose nanofibers in animal feed to improve animal performance.
纤维素纳米纤维的生产促进了农业食品加工过程中产生的植物残渣的利用。这些植物副产品的利用减少了环境污染。纤维素纳米纤维被应用于多个领域，包括制药、食品和动物营养行业。动物饲料中使用的许多纳米纤维来源经过加工后可作为潜在的纤维替代品，以提高效率。例如，在动物饲料中添加植物纤维的纳米颗粒（<100纳米）可能具有优异的物理特性，如高反应性、大表面积以及改善日粮营养物质的吸收。纳米技术改善了对动物胃肠道转运以及作为动物消化道中微生物发酵的能量来源和底物而言重要的纤维特性。纳米纤维可以改善挥发性脂肪酸的合成和血脂状况，对动物肠道健康产生积极影响。此外， 和 研究已证明在降低血糖水平方面有显著效果，且对身体无毒性作用。在日粮中添加纳米纤维可提高动物生产性能、增加产量，并朝着农业综合企业更可持续的经济发展迈进。据报道，在饲料中添加纳米矿物质还可提高肉类、牛奶和鸡蛋等动物产品的质量。总体而言，应用纳米技术利用农业副产品可提高动物生产系统的经济可行性和可持续性。因此，本综述对纳米技术利用方面的主要研究和进展进行了当前调查，重点关注动物饲料中的纤维素纳米纤维以提高动物生产性能。
