An individual feed intake model based on daily observed milk yield and body weight was tested on robotically milked cows of three different breeds. The average mean absolute errors were significantly (p < 0.05) lower than errors obtained with the NRC (2001) model - 2.10 vs. 2.43 kg; 2.24 vs. 2.49 kg; and 1.87 vs. 2.13 kg dry matter intake (DMI) - for the Danish Red, Holstein, and Jersey cows, respectively.
