ECM (Energy Corrected Milk)
BoviSync has a number of items that display different ECM (Energy Corrected Milk) values. These values only show for those herds that do regular DHI milk testing.
ECM = Energy Corrected Milk at last test day for the current lactation
PECM = Energy Corrected Milk at previous test day for the current lactation
2PECM = Energy Corrected Milk at second previous test day for the current lactation
BV_ECM305 = The predicted ECM during the first 305 DIM calculated by BoviSync using the most current test day information
BV_MEecm305 = Maturity corrected ECM for the first 305 DIM calculated by BoviSync using the most current test day information
The last two items shown are specific items only available in BoviSync. The BoviSync algorithm used to calculate these items is updated and recalculated periodically to stay current with the times. Animals must have at least one milk test at least seven days after fresh to generate a 305ME value.
