BESTPRED

BESTPRED gives Claude USDA’s best prediction method, the one used for official dairy lactation records since 1998, so it can work out lactation records from test days instead of estimating them. Ask for a herd’s 305-day records and Claude sends the test days (from a DHI or DairyComp export) to BESTPRED, which returns, for every lactation: projected 305-day and 365-day milk, fat and protein; mature-equivalent yields when the cow’s age and state are known; reliability; persistency; and a summary by parity with the least persistent cows. It can also project one cow’s record, draw her expected daily milk to day 305 to compare with what she’s giving, and give USDA’s mature-equivalent factors. The calculations are a Python port of USDA-AGIL’s BESTPRED 2.0rc7, checked against USDA’s own program (every output agrees to 1e-9). Test days sent to the service are used only for that answer and are not stored. To keep data on your own computer, install it locally instead: uvx bestpred-mcp.
