[Halal slaughter with and without stunning in sheep: implications on animal welfare and bleeding efficiency]

ABSTRACT The objective of this study was to evaluate the implications on animal welfare and the sangria efficiency in halal slaugther with and without stunning in sheep. 102 sheep were appraised in a commercial slaugthter, divided randomly for the weight in two groups: with stunning (CI) and without stunning (SI). It was verified that the animals without stunning presented straighten signs and vocalization after 20 seconds of decapitation. There was significant difference for erythrocytes (P<0.05), hemoglobin (P<0.01), leucocytes (P<0.01), stress of biomarkers CK (P<0.01) and lactate (P<0.01). Alterations in serum were not observed for glucose and AST. There was significant statistical difference for bleeding efficiency (P<0.01). The results demonstrated that there was stress in the halal slaugther with and without stunning and better bleeding efficiency in animals with traditional religious slaughter without stunning.
