Abstract

This study investigated how inclusion of grass/clover silage affected the time budgets and social behaviour of growing/ finishing pigs. The behaviour of 128 pigs was observed through video recordings. Pigs fed intact or chopped silage spent a larger proportion of their time active compared with pigs fed silage in pelleted form or fed only cereal-based feed. There was a trend for pigs fed silage in pelleted form or fed only cereal-based feed to respond strongly to social interactions more often than pigs fed intact or chopped silage, irrespective of initial performing pig behaviour. Pigs in groups fed intact silage had a lower number of wounds from violent social interactions on their bodies. Thus, additional provision of silage in an environment enriched with straw can further improve pig welfare.
