In automatic milking systems, cows are attracted to concentrate food that is contained in a robot. This not only increases the number of milkings, but also the amount of concentrate food consumed. An increase in concentrate food consumption can affect the cow’s appetite, feeding behaviour and digestion and subsequent milk production. Therefore, this study investigated the effect of two concentrate allowances: 1) the ‘candy concept’ with a minimum amount of concentrate (1.2 kg) to attract the cow, and 2) the maximum of 7 kg of food concentrate per day. Cows in the first treatment consumed approximately 3.5 kg of concentrate per day, and cows in the second treatment consumed approximately 5 kg of concentrate per day. However, the number of voluntary milkings did not differ between the two treatments.
