The present study was designed to investigate the effects of additional human contact (AHC) on the human–animal relationship (HAR) in broilers and on the birds’ productivity. A total of 1558 broiler one-day-old chicks were distributed into 12 equally sized pens at two different stocking densities (SDs), calculated on estimated weight at slaughter (4 pens with 32 kg/m ² and 8 pens with 16 kg/m ²). Six groups (2 high and 4 low SDs) received AHC, which consisted of 30-min sessions with visual human contact three days/week. The remaining six groups received as little human contact as possible and served as controls. A touch test was used to assess the human–broiler relationship and the production parameters measured were growth rate, mortality, feed consumption and feed conversion. The AHC treatment had a positive effect on the quality of the HAR but failed to affect any production parameter.
