Discover the MilkBot®
MilkBot® is a project to develop
technology to quantify both magnitude and shape of lactation curves
in a consistent and repeatable way. It is based on the simple observation that lactation curves vary,
no doubt influenced by genetics, environment, and health, and tools for characterizing that variation are
likely to be useful in understanding many problems in dairy herd management and dairy research.
There are two essential components to MilkBot® technology.
The MilkBot® Model
This is a simple nonlinear algebraic model predicting daily milk production as a function of DIM and
the four MilkBot® parameters, scale, ramp, offset, and decay. From fitted parameter values it is easy to calculated daily production at
any day in the curve, or M305, persistency, peak milk, peak day, and several other metrics.
The MilkBot® Fitting Engine
Calculating fitted parameter values from observed milk production data is complicated by the fact that
MilkBot is a nonlinear model, so the methods used for the more common linear models do not work.
We have developed a variety of fitting methods, including a very powerful maximum-likelihood genetic
algorithm that can fit a lactation starting from as little as a single data point. We provide access to
fitting software over the Internet as a service.
Publications and presentations describing MilkBot technology are listed on the
Publications page. Recent or upcoming items may be highlighted
on the DairySight News page. The MilkBot
fitting engine each get a dedicated page, and some possible
uses are discussed in the Applications page.
