    ABSTRACT: The aim was to conduct a retrospective study of the main epidemiological, clinical, pathological and laboratory findings from sheep suffering from obstructive urolithiasis, in the Agreste region of Pernambuco, Brazil. Thus, 66 medical records of non-castrated male sheep with age from 2 months and 5 years were analyzed. Most cases (79.63%) occurred during the rainy season. Most sheep were raised intensively (87.88%) and all were fed with concentrated ration. Main clinical signs were manifestation of pain, congestion of the mucosae, hyperthermia, and increased abdominal tension associated with urinary tract obstruction. Half of the animals showed total obstruction of the urethra, 69.7% of which died, whilst in cases of partial obstruction only 30.3% died. Laboratorial exams revealed neutrophilia and regenerative left turn, hyperfibrinogenemia, and azotemia. Urinalysis showed hematuria in 89.29% of the cases, and acidic pH in 46.43%. Erythrocytes, leukocytes, cell desquamation of urethral epithelium, and crystals of amorphous urate predominated in the examination of the sediment. Most frequent gross findings were pyelonephritis (61.54% of cases) and hydronephrosis (50%). In the ureter, ureteritis and hydroureter was observed. The bladder showed diffuse hemorrhagic cystitis (50%) and uroliths (57.69%). In the urethra, uroliths (61.54%) and diffuse hemorrhagic urethritis (57.69%) was found. The uroliths were composed mainly by hydrated calcium oxalate. It is concluded that in the Agreste region of Pernambuco, urolithiasis is an important disease of sheep with high mortality, associated with the ingestion of large amounts of concentrates and mineral supplements.

    ABSTRACT: RESUMO O presente trabalho objetiva relatar os principais tipos de distocias em cabras, no Agreste e Sertão de Pernambuco, avaliar os fatores relacionados com sua ocorrência e determinar a eficiência do tratamento utilizado (manobra obstétrica ou cesariana pelo flanco esquerdo). A maior incidência de partos distócicos ocorreu na estação chuvosa, com 84,6% dos casos. Os resultados mostraram predominância de distocias de origem materna (57,7%) sobre a fetal (42,3%), com maior incidência em cabras multíparas, mestiças e com gestações simples. A principal distocia materna foi a ausência ou dilatação cervical insuficiente, e fetal, alterações de atitude. A taxa de sobrevivência das mães alcançou 100 e 56,25%, enquanto suas crias atingiram 54,5 e 25%, após manobra obstétrica e cesariana, respectivamente, com predominância de cabritos vivos na primeira, e abortamentos na última. As manobras obstétricas e a cesariana pelo flanco esquerdo permanecem como opções seguras para o tratamento das distocias em cabras, quando realizadas em animais sem acentuada debilidade corporal ou endotoxemia grave, e também são importantes coadjuvantes, minimizando o impacto econômico causado por este distúrbio no Estado de Pernambuco. Palavras-chaves: cabras, distocias fetais, distocias maternas, índices de sobrevivência, procedimentos obstétricos. ABSTRACT The aims of the present study were to report the main dystocia causes in goats in Agreste and semiarid region of Pernambuco, evaluate factors related to their occurrence, and determine the efficiency of the treatment choice (obstetrical maneuver or left flank cesarean section). The incidence of dystocia was greatest in the rainy season ((84.6%). Results showed a major predominance of maternal dystocia (57.7%) over fetal dystocia (42.3%) with higher incidence in multiparous crossbreed goats with simple pregnancy. The main maternal dystocia was ringwomb while fetal dystocia was attitude alterations. Maternal survival rate achieved 100% and 56.25%, while kids reached 54.5% and 25% after obstetrical maneuver and cesarean

    ABSTRACT: The present work aimed to do a retrospective data analysis in 33 ewes with pregnancy toxaemia, focusing on the clinical and laboratorial aspects of the disturbance. The majority of the animals were raised intensively with free access to concentrate food and they were, at the final trimester of pregnancy, carrying two or more fetus. The laboratorial exams revealed hyperglycemia and ketonuria in most of the ewes. The clinical evolution varied from five to 17 days in the animals that died (42.4%) or received clinical discharge (57.6%), respectively. Thus, this work confirms that pregnancy toxaemia is a metabolic disorder leading to important economic losses in Pernambuco State, Brazil, due to the mortality of ewes and lambs.

    ABSTRACT: The carpal joint in goats is subject to diseases such as caprine arthritis encephalitis, leading to pain and a reduction in movement. Due to the scarce records of normal parameters, the aim of the present study was to assess the physiochemical and cytological make up of the synovial fluid in the carpal joint of 44 mixed-breed goat without joint disease. The following physiochemical characteristics were assessed: volume (0.94mL ± 0.26 mL), color (colorless to yellow), turbidity (46.50% were limpid), mucin precipitation (firm coagulant in limpid solution) and concentration of total proteins (1.95 ± 0.87 mg/dL). Cytological assessment consisted of global and differential leukocyte counts. The mean global count was 48.02 ± 24.47 cells/µL. The differential count was 25.07 ± 15.86 lymphocytes/µL and 16.31 ± 12.63 large mononucleated cells/µL. It is suggested that the parameter values obtained in the present study may be considered normal for synovial fluid in the carpal joint of adult mixed-breed goats.KEY WORDS: Carpus, goat, joint, synovia. A articulação do carpo dos caprinos é alvo de enfermidades, como a artrite-encefalite caprina, levando à dor e à redução dos movimentos. Devido à falta de registro de parâmetros normais, este estudo avaliou a constituição físico-química e citológica do líquido sinovial da articulação do carpo de 44 caprinos sem raça definida, que não apresentavam doença articular. Os parâmetros físico-químicos avaliados foram volume (0,94 mL ± 0,26 mL), cor (incolor a amarelo), turbidez (46,50% apresentaram-se límpidas), precipitado de mucina (coágulo firme em solução límpida) e concentração de proteínas (1,95 ± 0,87 mg/dL). Os dados citológicos corresponderam às contagens global e diferencial de leucócitos. A contagem global média encontrada foi de 48,02 ± 24,47 células/µL e contagem diferencial com 25,07 ± 15,86 linfócitos/µL e 16,31 ± 12,63 grandes células mononucleadas/µL. Sugere-se que os valores obtidos nesta pesquisa sejam considerados parâmetros normais para o líquido sinovial do carpo de caprinos adultos sem raça definida. PALAVRAS-CHAVES: Articulação, caprino, carpo, sinóvia.

    ABSTRACT: Introdução A toxemia da prenhez (TP) é uma doença importante no semi-árido ocorrendo, principalmente em ovelhas e cabras, suplementadas com concentrado, com bom estado nutricional (TP tipo 2), em fazendas produtoras de animais para a venda como reprodutores (animais de alta genética). Ocorre também em animais que não estão gordos, com escore corporal de 2 a 3 (TP tipo 1) [5]. A TP é caracterizada por hipoglicemia, cetonemia, cetonúria, debilidade e cegueira, presente em gestações gemelares, uma vez que o aporte nutricional se torne insuficiente para o desenvolvimento dos fetos. A enfermidade ocorre devido a uma baixa ingestão de energia, tendo como conseqüência a excessiva mobilização de gordura. Este excesso de gordura ultrapassa a capacidade do fígado em metabolizá-la, formando corpos cetônicos, os quais são responsáveis por alterações patológicas do sistema nervoso central [4,5,6]. As exigências nutricionais de fêmeas gestantes apresentam-se bastante elevadas no terço final da gestação (situação agravada com gestações gemelares). Objetivou-se avaliar o perfil de indicadores bioquímicos sanguíneos e urinários em ovelhas da raça Santa Inês durante o terço final da gestação, parto e pós-parto, e sua relação com o aparecimento de toxemia da prenhez.

    ABSTRACT: The aim of the present study was to report the main dystocia causes in sheep in Agreste and semiarid region of Pernambuco and to evaluate some factors related to their occurrence, besides of determining the efficiency of the treatment choices. The higher incidence of dystocia occurred in rainy season corresponding to 61.7%. Results showed a major predominance of maternal dystocia (71.6%) over fetal dystocia (29.4%) with higher incidence in primiparous and gemelar pregnant Santa Inês ewes. The main maternal dystocia was ringwomb while fetal dystocia was maldisposition in anterior presentation. Maternal survival rate correspond to 100% and 88.6%, while lambs achieved 41.2% and 46.7% after obstetrical maneuver and caesarean section, respectively, with predominance of unviable lambs in both procedures. Obstetrical maneuver and left flank cesarean section remain as safe options for the treatment of sheep dystocia and are also important coadjutants in minimizing the economical impact that this disease causes in Pernambuco.

    ABSTRACT: A sarna corióptica é de rara ocorrência em caprinos, no entanto trata-se de uma enfermidade cutânea importante, resultando em perdas econômicas decorrentes do retardo no desenvolvimento dos animais, da perda de peso e do prejuízo à indústria de couro. Desse modo, o objetivo do presente artigo é relatar a ocorrência de um surto de sarna corióptica em um rebanho caprino criado no município de Gravatá (Lat. 08° 12’ 04’’ S e Long. 35° 33’ 53’’ O), região Agreste do estado de Pernambuco. Os animais apresentavam extensas áreas de alopecia, eritema, crostas e espessamento da pele na região das axilas, peito, ventre e as faces caudal e craniomedial dos membros posteriores, além de intenso prurido. Foi realizado raspado cutâneo e identificado o ácaro Chorioptes bovis spp.PALAVRAS-CHAVES: Caprinos, Chorioptes spp, sarna. Chorioptic mange is of rare occurrence in goats, although it is an important skin disease resulting in economic loss due to the delay in the development of the animals, weight loss and economic losses to the leather industry. Thus, the aim of the present article was to report the occurrence of an outbreak of chorioptic mange in a goat flock reared in the city of Gravatá, (Lat. 08° 12’ 04’’ S and Long. 35° 33’ 53’’ W) in Pernambuco´s Agreste region. The animals showed wide alopecia areas, erythema, crusts and skin thickness in the following areas: armpits, sternum, ventral abdomen, caudal and cranium-medial facets of the hind legs and severe scratching. Chorioptes bovis spp was identified in skin scrapings.KEY WORDS: Chorioptes spp, goats, mange.

    ABSTRACT: No references were found in the literature reporting natural intoxication in goats by species of Dieffenbachia sp. because of its restricted access to livestock. Thus, the objective of the current work was to report the clinical and laboratorial findings in a case of natural intoxication by Dieffenbachia sp. in a goat. In the clinical examination, hyperthermia, dehydration of about 10%, subcutaneous edema from the submandibular to the xiphoid area, exteriorized tongue with edema and focal laceration areas in its dorsal side, ptyalism and gastrointestinal hypomotility were all observed. The laboratorial alterations were leukocytosis by neutrophilia, hyperfibrinogenia and a severe rise in serum creatinine kinase activity. This work shows the real possibility of the intoxication by Dieffenbachia sp. and the necessity of restricting animal access to this plant.

    ABSTRACT: RESUMO: Não foram encontrados na literatura pesquisada relatos de intoxicação natural em caprinos por espécies de plantas do gênero Dieffenbachia, visto que estas são de difícil acesso aos animais pecuários. Deste modo, o objetivo no pre-sente artigo foi relatar os achados clínicos e laboratoriais de um caso de intoxicação natural por Dieffenbachia sp. em um caprino. Ao exame clínico foi observado hiper-termia, desidratação em torno de 10%; edema subcutâneo estendendo-se da região submandibular até a xifóide; língua exteriorizada, edemaciada e com áreas focais de laceração em sua porção dorsal; sialorréia intensa e hipomotilidade gastrintestinal. As alterações laboratoriais encontradas foram leucocitose por neutrofilia, hiperfibri-nogenemia e aumento expressivo da enzima creatina quinase (CK). Neste trabalho mostra-se a ocorrência da intoxicação por Dieffenbachia sp., sendo necessário res-tringir o acesso dos animais a esta planta. Termos de indexação: intoxicação natural, Dieffenbachia sp., caprino.
