To determine if beef bulls adjust their chewing pattern to avoid ruminal acidosis, the chewing behaviour of double-muscled (dm) and non-dm bulls was studied with a concentrate based diet, with and without straw. The conformation (dm or not) had no influence on chewing behaviour. The removal of the straw resulted in an importantly increased DM-intake. When fed 100% concentrates, significant rumination activity was recorded. Removing the roughage from the diet had no influence on time of eating, but induced a slight shift towards relatively more rumination during the second half of the day.
