Abate halal com e sem insensibilização em ovinos: implicações sobre o bem-estar animal e a eficiência da sangria / [Halal slaughter with and without stunning in sheep: implications on animal welfare and bleeding efficiency]

O objetivo deste estudo foi avaliar as implicações sobre o bem-estar animal e a eficiência da sangria no abate halal com e sem insensibilização em ovinos. Foram avaliados 102 ovinos, em abate comercial, separados randomicamente pelo peso em dois grupos: com insensibilização (CI) e sem insensibilização (SI). Verificou-se que os animais sem insensibilização apresentaram sinais de endireitamento e vocalização após 20 segundos da degola. Houve diferença significativa para hemácias (P<0,01), hemoglobina (P<0,01), leucócitos totais (P<0,001), bem como para os biomarcadores de estresse, como CK (P<0,01) e lactato (P<0,001). Apesar de não apresentarem diferença estatística significativa, o LDH e o cortisol ficaram acima dos valores basais em ambos os grupos. Não foram observadas alterações séricas para glicose e AST. Houve diferença estatística significativa para eficiência da sangria (P<0,01). Os resultados demonstraram que houve estresse no abate halal com e sem insensibilização e melhor eficiência da sangria em animais não insensibilizados.(AU)

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.(AU)

Epistaxes: um desafio para o clínico na busca do prognóstico / Epistaxis: a challenge for clinicians in the search for prognosis

Background: Ailments that affect guttural pouches (GPs) include congenital malformations, tumors, and, especially, infections. Clinical signs of disorders of the GPs are not always specific, and include nasal secretion, epistaxis, and enlargement of regional lymph nodes. Deficient diagnosis and treatment tend to limit life expectancy. Some cases can lead to terminal exsanguination due to progression of the disorder if not diagnosed or if treatment fails. Unusual presentations may occur, and these cases require knowledge for prompt action and determination of the prognosis. The objective of this work is to report one of these unusual cases: epistaxis caused by rupture of the GP by a pharyngeal abscess.Case: A 6-year-old mare was presented for examination exhibiting purulent nasal secretion that had been ongoing for approximately 45 days (which had been treated as strangles for 7 days) and intermittent epistaxis for the past 20 days. When the mare was taken to the Veterinary Hospital, it also exhibited dysphagia with purulent nasal secretion mixed with the ingested food, a body condition score of 3/9, wheezing, mild ataxia, anemia (2.8 million RBCs/mm3 ; hematocrit = 14%), leukopenia (4,600 WBCs/mm3), and hyperfibrinogenemia (600 mg/dL). Upper airway endoscopy revealed presence of blood in the anterior third of the trachea, a blood clot in the left GP, and absence of bacterial of fungal plaques. Analysis of the bloody material collected from the GP showed presence of cocci bacteria and neutrophils. The treatment initially implemented was antibiotic therapy with enrofloxacin. Epistaxis worsened on the day following admission. Blood transfusion was carried out, but this procedure was not effective as profuse acute hemorrhage took place and led to death of the patient 48 h after admission. At necropsy, the left GP was laden with blood clots and serous/bloody content, and exhibited a circular/cylindrical lesion in its retropharyngeal portion.[...]
