Summary:

Weaning is a highly stressful time for piglets, with multiple significant changes occurring simultaneously (change in diet, environment, mixing with unfamiliar piglets). Weight loss and increased cortisol levels have been observed for the first few days aft er weaning, indicating this is a stressful event for piglets. Inadequate food intake in the first two days aft er weaning, in combination with the stress of weaning, decreases piglet performance, resulting in increased disease susceptibility and mortality through changes in metabolic and immune function. Promoting solid feed intake before weaning by provision of creep feed familiarizes the piglets with solid food. Piglets that consume creep show better feed intake and improved growth rate in the critical weaning and post-weaning period. However, previous work conducted at the Prairie Swine Centre shows that the amount of creep feed consumed is oft en very low, and a high number of piglets fail to eat creep.

Previous research by others has determined that the amount of creep consumed by piglets can be increased by provision of a specially designed feeder that encourages exploratory interaction around the feeder. It is known that piglets raised outdoors are quick to consume starter feed and will oft en ingest soil and plant material while exploring their environment. However, piglets reared indoors do not have the same opportunity for exploration. This study builds upon current knowledge to investigate the effects of provision of environmental enrichment within the farrowing pen and nursery on exploratory behaviour, frequency of visits to the creep feeder, creep consumption and piglet growth rate. If simple enrichment can increase creep feed consumption in piglets this could result in reduced stress at weaning and better growth in the post-weaning period.
