Environmental enrichment using substrates changes the behaviour of pigs by increasing the time spent exploring the environment and reducing the amount of penmate-directed behaviour (Beattie et al., 1995). The objective of the present study was to assess whether performance and meat quality are also affected by environmental enrichment.
In a randomised block design, three-hundred and twenty Large White x Landrace pigs were allocated to one of two environmental treatments from birth to slaughter. Five blocks were used, each containing eight groups of eight pigs. In each block, four groups were reared in barren environments which had slatted floors and recommended space allowances.
