Table 2.

A summary of the training, testing, and total datasets. Cow information and descriptive statistics for the measured metrics including the body condition score (BCS), scale-measured weight, and metabolic body weight (MBW = BW^0.75) and the predicted metrics, including the predicted weight, co-efficient of determination for predicted weight vs. the measured weight, mean absolute error (MAE), and mean absolute percentage error (MAPE) are calculated
