摘要: Abstract In this study, the effects of artificial boar stimuli on oestrus expression in sows were compared to that a boar. During consecutive cycles, 12 gilts and 38 subjected one three treatments. A Back-Pressure-Test (BPT) was carried out twice daily presence robot (R) with: (1) olfactory auditory (R+O+A), (2) (R+A) or (3) without additional (R). As reference, BPT mature 30min after procedure. With boar, detection rate higher (100% versus 66% 81% (R+A), 75% (R); P >0.10). Artificial, did not add visual stimuli. Furthermore, results better than combination all
