N2 - This study analyses tail and ear postures of growing pigs in two different housing systems throughout the growing period. On one farm, 168 undocked pigs (84: barren housing, 84: enriched housing) were observed individually at three time periods: beginning, middle and end of the growing period. By scan sampling, the tail (curled-up, raised, hanging, tucked under, wagging) and ear posture (forwards, sidewards, backwards, mixed) was noted. Scans were performed hourly during the activity periods by direct observation. Moreover, the body posture (standing, feeding, lying (eyes open), lying (eyes closed) and tail lesions were noted. Data were analysed using the GLIMMIX procedure in SAS. Results revealed significant differences between the enriched and barren group especially for curled-up tails, tucked under tails and ears directed forwards. More curled-up tails and ears directed forwards occurred in the enriched and more tucked under tails in the barren habitat. The time period of observation also had significant influences. Tail lesions had significant effects on most tail postures. Most ear postures were influenced by the body posture of the pigs. Overall, this study contributes to the understanding of body language, specifically tail and ear postures in pigs.
