# HerdManager.co — Dairy Farm Management Software | International & Pakistan Editions

> HerdManager.co (Herd Manager) is cloud-based dairy farm management software for commercial dairy cattle farms, priced at $5 USD per animal per year, with two public editions: international (`/`) and Pakistan (`/pk`). The farm app covers per-cow milk recording (morning, afternoon and evening sessions), health and vaccination records with medicine withdrawal alerts, breeding and calving with synchronisation protocols, NRC-based ration analysis and per-pen feed plans, stock alerts, farm accounts with HR and payroll, 80+ PDF/Excel reports, and an AI farm assistant powered by DeepSeek. The public site also offers 18 free, no-login dairy calculators and a library of dairy farming guides. Herd Manager is built by a small team in Islamabad, Pakistan. The app interface is in English; you can ask the AI assistant questions in Urdu or Roman Urdu and it will usually reply in kind. It is built for dairy cattle; buffaloes can be recorded under breed "Other", but breeding dates use cattle gestation timings.
