Of 8 pairs of identical twins, one brother was fed 500 g protein daily and the other bull 700 g, from 18 mth of age. At 5 yr of age, live weight in the underfed bulls was 235 kg lower than in the others. Sexual behaviour, as assessed by total semen collection time, number of mounts/copulation, interval to 1st mounting, and interval between copulations, was superior in the underfed bulls. Reaction times in the underfed bulls were significantly shorter.
