使用须知
了解 Feedy V4.561 正式版在原料档案、数据库参考、本批净能、采购价值与成本试算中的适用范围，以及完整配方设计功能的开发状态。
1. 使用定位
Feedy 是猪营养与原料价值决策工作台。当前可使用营养速查、本批净能评估、采购价值评估和配方成本试算；独立的完整配方设计与优化功能仍在开发。Feedy 不是实验室检测系统或 ERP，也不替代企业正式配方审批、现场生产验证和质量管理流程。
2. 数据差异
同名原料在不同国家、数据库、工艺和规格下可能存在明显差异。跨数据库比较时，应同时查看英文原名、recordId、规格、加工方式和营养组成。
3. 本批净能预测
系统预测适合早期筛选与试算，核心预测结果为猪净能。CF、淀粉、NDF、ADF 等辅助模型参数不等同实验室检测；已有可靠化验值、企业定值或供应商正式检测结果时，应优先使用更可靠数据。
4. 配方成本试算（采购价值第二页）
成本试算用于快速回答“更换原料、调整用量或价格变化后，成本大约怎样变化”。它允许只输入部分主要原料，不要求组成完整的 1000 kg/t 配方，也不把部分原料组合呈现为正式营养水平或作达标判断。若输入当前完整吨料成本，系统仅在“未录入部分保持不变”的假设下估算调整后成本。
5. 配方设计与优化（开发中）
该入口将用于完整配方设计，未来会要求明确原料参数来源、原样（as-fed）基础、营养目标以及 Min / Max / Fixed 等边界。当前版本只展示独立的功能入口和开发状态，不提供可执行的完整配方设计或正式最低成本优化结果，也不以成本试算替代该功能。
6. 本地数据
当前生产环境未启用账号或云端工作区。本批原料、修改过的测算参数和配方方案保存在当前浏览器；清理网站数据、使用无痕模式或更换设备可能导致记录不可用，请定期导出重要记录。
7. 推荐使用环境
建议使用最新版桌面 Chrome 或 Edge。手机端更适合查询与查看；完整配方录入、参数来源核对和方案管理建议使用桌面浏览器。
8. 数据问题
如果发现中文名称、国外对应关系、规格或营养数据存在疑问，可使用营养速查中的问题反馈入口生成标准化反馈。
Usage Notice
Scope and limits of Feedy V4.561 Production ingredient profiles, database references, batch estimates, procurement value and cost trials, plus the development status of full formulation design.
1. Product positioning
Feedy is a pig-nutrition and ingredient-value decision workbench. Nutrient Lookup, Batch Net Energy, Procurement Value and Formula Cost Trial are currently available; the independent Formulation Design & Optimization module remains in development. Feedy is not a laboratory system or ERP and does not replace formal company approval, production validation or quality-management processes.
2. Database differences
The same ingredient name can represent materially different products across countries, databases, processes and specifications. Cross-database comparison should consider the original English name, record ID, specification, processing method and nutrient composition together.
3. Batch net-energy estimates
Model estimates support early screening and what-if analysis. Supporting CF, starch, NDF and ADF estimates are not laboratory measurements; reliable analytical or company values should take priority when available.
4. Formula Cost Trial (Procurement Value, page 2)
Formula Cost Trial answers how cost changes when ingredients, inclusion rates or prices change. It may use only selected major ingredients, does not require a complete 1000 kg/t formula and does not present the partial mixture as a formal nutrition assessment. A projected total cost assumes omitted ingredients remain unchanged.
5. Formulation Design & Optimization (in development)
This independent module is intended for complete formulas with explicit parameter provenance, an as-fed basis, nutrient targets and ingredient Min/Max/Fixed bounds. The current release exposes only the dedicated entry and development status. It does not provide executable full-formulation or formal least-cost results, and Formula Cost Trial is not presented as a substitute.
6. Local data
The current production environment does not enable accounts or cloud workspaces. Batch ingredients, modified calculation parameters and formula plans remain in this browser. Clearing site data, private browsing or changing devices can make records unavailable, so export important records regularly.
7. Recommended environment
Use the latest desktop Chrome or Edge. Mobile is better suited to lookup and viewing; full formulation entry, source review and plan management are recommended on desktop.
8. Data issues
If a Chinese name, foreign-equivalence note, specification or nutrient value appears questionable, use the structured issue-feedback entry in Nutrient Lookup.
