摘要

天然多糖在水产饲料配方中显示出相当大的潜力,可以作为粘合剂,增强水的稳定性,减少水生环境中的养分浸出和颗粒分解。本试验采用羧甲基纤维素(D0,对照)、紫薯(D1)、芋头根(D2)和糯米(D3) 4种不同的黏合剂配制4种异蛋白饲粮(32%粗蛋白质)。每一种饲料分别饲喂平均初始体重为6.66±0.01 g的亚洲鲶鱼(Clarias batrachus),进行为期90天的试验,以评估其生长性能、饲料稳定性、全身成分、健康参数和经济可行性。结果表明,黏合剂类型对颗粒耐久性指数、可浮性和溶胀率有显著影响(p 2饲粮显著高于p 2组,表现出最有利的结果)。此外,D2组鱼的p值显著高于D3组,D3组鱼的肠道结构得到改善,其特征是绒毛长度增加,杯状细胞密度增加,固有层拉长。相反,饲喂D0和D3饲料的鱼表现出空泡细胞质增加和细胞核退行性变。此外,经济分析显示,D2日粮显著提高了经济效率(p 2),改善了生长性能、饲料稳定性、健康状况和经济回报,使其成为传统粘合剂的有希望的替代品。

Effects of plant-origin binder sources in Asian catfish diets on growth, feed quality, blood chemistry, liver and gut health, and economic efficiency.

Natural polysaccharides have demonstrated considerable potential as binding agents in aquafeed formulations, enhancing water stability and reducing nutrient leaching and pellet disintegration in aquatic environments. In this study, four isoproteic diets (32% crude protein) were formulated using different binders: carboxymethyl cellulose (D0, control), purple fingerling potato (D1), taro root (D2), and glutinous rice (D3). Each diet was administrated to Asian catfish (Clarias batrachus) (mean initial weight: 6.66 ± 0.01 g) over a 90-day trial to evaluate growth performance, feed stability, whole-body composition, health parameters, and economic feasibility. The results indicated that binder type significantly affected pellet durability index, floatability, and swelling rates (p < 0.05). Notably, fish fed the D2 diet exhibited significantly higher (p < 0.05) feed attractability and palatability. Growth performance metrics, including final weight, weight gain, total biomass, specific growth rate, feed conversion ratio, and protein efficiency ratio, varied significantly (p < 0.05) among dietary treatments, with the D2 group demonstrating the most favorable outcomes. Additionally, fish from the D2 group exhibited significantly higher (p < 0.05) crude protein levels lower crude lipid content in whole-body composition. The dietary binders also had significant impact (p < 0.05) on hemato-biochemical indices, except for monocyte levels. Histological analysis indicated that fish in the D2 and D3 groups exhibited improved intestinal structure, characterised by increased villi length, a higher density of goblet cells, and an elongated lamina propria. In contrast, fish fed the D0 and D3 diets displayed increased vacuolar cytoplasm and degenerative nuclei. Furthermore, economic analysis revealed that the D2 diet significantly enhanced economic efficiency (p < 0.05) compared to other treatments. In conclusion, incorporating taro root as a binder in the diet of Asian catfish (D2) improved growth performance, feed stability, health status, and economic returns, making it a promising alternative to conventional binders.

期刊介绍: We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
