ABSTRACT
Os mercados importadores de carne de frango brasileira estão se tornando cada vez mais exigentes em termos de adesão aos princípios do bem-estar animal na criação e abate dos frangos. Um dos principais problemas relacionados ao bem-estar animal na cadeia de produção do frango de corte é o manejo pré-abate. Portanto, o objetivo deste estudo foi observar as principais causas de perdas e eliminação dos frangos de corte no abate emergencial em um abatedouro comercial e discutir possíveis formas de solucioná-las. Para tanto, foram implantados ábacos nas três linhas de abate ao lado do local da pendura das aves e registrado o número de aves que foram eliminadas ou estavam mortas, durante 10 dias, nos dois turnos de abate em um abatedouro comercial. Foram abatidas no experimento 4.563.293 aves, sendo que o total de perdas foi de 14.046 aves (0,3%). A mortalidade no transporte e/ou galpão de espera foi a principal causa de eliminação no abate emergencial (80,56%), seguida por aves pequenas refugos (19,1%), doentes injuriadas (0,18%) e lesionadas (0,11%). Conclui-se que para reduzir as perdas no pré-abate, os esforços devem ser direcionados principalmente na logística de transporte, visando assim à lucratividade do produto, pautado no contexto atual de bem-estar animal.
Brazilian chicken import markets are becoming increasingly demanding in terms of adhering to the principles of animal welfare in raising and slaughtering chicken. Thus, adapting the poultry to such requirements requires preslaughter failures control, that are main animal welfare problems in broiler production is preslaughter management. Therefore, the objective of this study wasto establish and quantify the main causes of losses related to pre-slaughter management in a commercial chicken slaughterhouse.In this way, abacuses were implanted next to the hanging in the three slaughter lines and the number of broilers eliminated or that were death on arrivals was recorded, for 10 days, in both slaughter shifts. 4.563.293 broilers were slaughtered in the experiment and the total number of boilers eliminated in the emergency slaughter were 14.039 birds (0.3%). The death on arrivals was the leading cause of elimination in emergency slaughter (80.56%), followed by small broilers (19.1%), injured broilers (0.18%) and fractured broilers (0.11%). It is concluded that to reduce preslaughter losses, efforts should be directed mainly to transport logistics andimprovements in the waiting shed, aiming to decrease mortality losses in this stage.

Abstract The aim of this study was to provide the first report on a new host for the digenean Paratanaisia bragai in the caninde macaw Ara ararauna along with the pathological aspects of the infection in the new host. The microscopic findings revealed the presence of granulomatous interstitial nephritis. This study contributes towards knowledge of parasitism by P. bragai in A. ararauna, and emphasizes the need to use best practices in wildlife conservation parks.
Resumo O objetivo deste estudo foi relatar, pela primeira vez, a arara canindéAra ararauna como um novo hospedeiro para o digenéticoParatanaisia bragai, bem como relatar aspectos patológicos relacionados à infecção no novo hospedeiro. Os achados microscópicos revelaram nefrite intersticial granulomatosa. Este estudo contribui para o conhecimento do parasitismo por P. bragai em A. ararauna e ainda faz um alerta para a adoção de boas práticas de criação em criatórios conservacionistas da fauna silvestre.

In the aviculture industry, the use of Lactobacillus spp. as a probiotic has been shown to be frequent and satisfactory, both in improving bird production indexes and in protecting intestine against colonization by pathogenic bacteria. Adhesion is an important characteristic in selecting Lactobacillus probiotic strains since it impedes its immediate elimination to enable its beneficial action in the host. This study aimed to isolate, identify and characterize the in vitro and in vivo adhesion of Lactobacillus strains isolated from birds. The Lactobacillus spp. was identified by PCR and sequencing and the strains and its adhesion evaluated in vitro via BMM cell matrix and in vivo by inoculation in one-day-old birds. Duodenum, jejunum, ileum and cecum were collected one, four, 12 and 24 h after inoculation. The findings demonstrate greater adhesion of strains in the cecum and an important correlation between in vitro and in vivo results. It was concluded that BMM utilization represents an important technique for triage of Lactobacillus for subsequent in vivo evaluation, which was shown to be efficient in identifying bacterial adhesion to the enteric tract.

Infecções fúngicas causadas por Macrorhabdus ornithogaster, Aspergillus flavus, Candida albicans tem sido descritas em várias espécies aviárias sendo responsáveis por promover alterações gastrointestinais, respiratórias, neurológicas e dermatológicas entre outras. O presente artigo descreve aspectos clínicos, anatomopatológicos, procedimentos diagnósticos, medidas preventivas e terapêuticas de um caso crônico de três infecções fúngicas concomitantes em periquitos australianos (Melopsittacus undulatus) provenientes de um criatório comercial encaminhado ao laboratório de Ornitopatologia do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade Estadual Paulista (FMVZ UNESP), campus Botucatu São Paulo, Brasil.
Fungal infections caused by Macrorhabdus ornithogaster, Aspergillus flavus, Candida albicans has been described as responsiblefor promoting gastrointestinal, respiratory, neurological and dermatological disorders in several avian species. The present paperdescribes the clinical signs, histopathological exams, treatment and preventions and of a chronic case of three fungal infectionsconcomitant in australian parakeet (Melopsittacus undulatus). The animals came from a commercial breeding facility and sent toOrnitopathology Laboratory of the Veterinary Hospital, Veterinary Medicine and Animal Science Faculty, Paulista State University(FMVZ - UNESP), Botucatu campus - São Paulo, Brazil.

The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode species in the body cavity, near the cervical air sac and lung region. This study contributes towards knowledge of parasitism in Brazilian wild birds and an anatomical region of the host as an infection site for Pelecitus sp.
O objetivo do estudo foi relatar, pela primeira vez, a coruja buraqueira Athene cunicularia como um novo hospedeiro para o nematóide filarídeo Pelecitus sp. do Sudeste do Brasil, bem como a ocorrência desta espécie de nematóides na cavidade corporal, próximos à região dos sacos aéreos cervicais e pulmões. Este estudo contribui para o conhecimento do parasitismo em aves silvestres brasileiras e uma região anatômica do hospedeiro como sítio de infecção para Pelecitus sp.
