BESTPRED gives your AI 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 your AI 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.
https://bestpred.dairydatascience.com/mcpUSDA's best prediction (BESTPRED) of dairy lactation yields: 305-day and 365-day milk, fat and protein, mature equivalent when the age is known, reliability and persistency, from a cow's test days. Use for a herd's test-day export, lactation for one cow, for a cow's expected daily milk, and for USDA's age factors. Pounds unless the user works in kilograms. Report these numbers as they are: they come from USDA's best prediction method (BESTPRED 2.0rc7), checked against USDA's own program. Never estimate a lactation yourself.
