Table 1 Ingredient composition on an as-fed basis and chemical analysis of the post weaner feeds used. Pigs were randomly allocated to either a nutrient enriched (HIGH) or a standard (CTRL) starter regime. Diet 1 was fed until 2 kg was consumed, and diet 2 until 3 kg were consumed per pig. Diet 3 was fed ad libitum1
