Alternative feed components to replace fishmeal and fish oil in carp feed

Some potential alternative ingredients to fish meal and fish oil replacement in carp feed were identified. Detailed information on the ingredients, i.e. alternative protein or lipid sources for carp, are compiled into an open access, online database. The feedstuff inventory coined as “ZeroFish CarpFeed” (acronym: fish meal fish oil free carp feed ingredients database) is an applied output of a national project funded by the Czech Ministry of Agriculture (Grant: MZe ČR Projekt NAZV QK1810296). The database is tailor-made for direct usage by carp feed formulators, especially by farm managers or for small scale feed manufacturers.

The alphabetically-arranged, filter-search enabled database is divided into 5 inventories: (a) ingredient ‘crude’ data, cross matched with carp specific limits; (b) ingredient ‘digestible’ data, derived from apparent digestibility coefficients (ADC) of common carp; (c) digestibility ranges for individual ingredients (ADCprotein≈ ADCamino acids; ADClipid≈ ADCfatty acids); (d) feed formulation files and guide, and; (e) model formulations that are balanced and least cost. In total, our database covers 34 alternative ingredients (excluding their variants) that can offer alternative to fish derivatives in carp feed, when used in combination. They are divided into 18 protein sources (both classic and modern), 9 ‘filler’ sources and 7 oil (lipid) sources. The ingredient data are visualized, and color coded for highlighting relative abundance (among other ingredients) and its goodness (whether optimum or deficient for carp) respectively.

经研究，已确定若干替代鱼粉及鱼油用于草鱼饲料的潜在成分。关于这些成分的详细信息，即草鱼的替代蛋白或脂质来源，已编纂成一份开放获取的在线数据库。该数据库名为“ZeroFish草鱼饲料”（缩写：鱼粉鱼油无草鱼饲料成分数据库），系一项由捷克农业部资助的国家级项目（资助编号：MZe ČR Projekt NAZV QK1810296）的应用成果。该数据库专为草鱼饲料配方师直接使用而量身定制，尤其适用于农场管理者或小型饲料生产商。该数据库按照字母顺序排列，并具备过滤搜索功能，分为五个部分：(a) 成分‘粗’数据，与草鱼特定的限制条件进行交叉匹配；(b) 成分‘可消化’数据，源自常见草鱼的表观消化率系数（ADC）；(c) 单一成分的消化率范围（ADC蛋白≈ ADC氨基酸；ADClipid≈ ADC脂肪酸）；(d) 饲料配方文件及指南；(e) 平衡且成本最低的模型配方。总计，我们的数据库涵盖了34种替代成分（不包括其变体），在组合使用时，可提供替代鱼衍生物的选项。这些成分分为18种蛋白质来源（包括经典和现代来源）、9种‘填充’来源和7种油脂（脂质）来源。成分数据已进行可视化处理，并采用颜色编码以突出相对丰度（与其他成分相比）及其对草鱼的益处（是否为最佳或不足）。
