The behaviour of eight litters of Large White x Landrace piglets aged 3 weeks was scored in flat-deck cages every 2 min for 12 h during the day, noting the frequences of 11 behaviour patterns. Similar observations were made at 6 weeks of age, and five main activities at the two ages were compared. There was a significant decrease in the frequency of aggressive encounters between the two ages, while the other activities remained at the same frequencies. The proportion of scores devoted to the main activities is given.
