Ad libitum MR-fed calves vary in their feeding behavior and individual feed intake during the preweaning period. This study intended to classify ad libitum MR-fed calves according to their individual voluntary MR intake using a clustering approach. Analysis allowed discriminating two groups of calves with different MR meal size (HIGH; 2.2 ± 0.11 L MR/visit; LOW; 1.8 ± 0.07 L MR/visit). Differences in feeding behaviors were linked to growth performance and metabolic changes.
