Weaning of the piglet from the sow commonly results in a growth check immediately post weaning, while the piglet adapts to the new conditions and feed source. Offering solid creep feed during lactation aims to reduce this post weaning growth check. Several studies have outlined the benefits of creep feeding, however these benefits are not always observed and may not influence lifetime performance. Piglets weaned at an older age are likely to consume more creep feed than those weaned younger, therefore it is hypothesised that offering creep feed during lactation may have fewer benefits for early weaned animals. In addition, there is evidence to suggest an interaction between weaning age and the ingredient composition of the creep diet (Callesen et al., 2007). The aim of this experiment was to determine the impact of offering different creep diets during lactation on lifetime growth performance and carcase composition of pigs weaned at 22 or 29 d of age.
