Causes of death in goats in Rio Grande do Sul state, Brazil: analysis of 322 cases (2000-2016)

Abstract

The diagnosis of the cause of death in goats submitted to necropsy from January 2000 to December 2016 by Setor de Patologia Veterinária from the Universidade Federal do Rio Grande do Sul was reviewed. Epidemiological features, such as the breed, sex and age, in addition to the clinical and pathological features were evaluated. During this period, 322 goats were necropsied, in which a conclusive diagnosis was obtained in 290 (90%) goats. Goats that were part of other experimental study were excluded from this study. From these 290 cases, 167 (57.6%) corresponded to diseases of infectious origin and toxinfectious diseases, while 123 (42.4%) were classified as non-infectious conditions. Infectious diseases included 55 cases of bacterial origin, 59 cases with parasitary involvement, 14 cases of viral origin, and 39 toxinfectious cases. Non-infectious conditions were grouped into metabolic diseases (44 cases), plants or chemical substances poisoning (36), mineral and nutritional deficiencies (20), and neoplasms and developmental disorders (5). In the remaining 18 cases, a conclusive diagnosis was obtained, however the conditions did not fit into those criteria and were classified as “others”. The age range of the goats in this study was from 1 day-old to 10 years-old. Most of the goats were females (201), while 121 were males. Affected breeds included Boer, Saanen, Anglo-Nubian, Toggenburg and mixed breeds. Parasitic, infectious and toxin-infectious diseases were the main cause of deaths, especially haemonchosis, pleuropneumonia, eimeriosis and enterotoxemia. Among the non-infectious conditions, metabolic disorders, especially rumen acidosis, pregnancy toxemia and urolithiasis, were directly related to the management employed in the property. Plant poisoning diagnosis was also highlighted with locally present plants, such as Sida carpinifolia, as the most important.

Causes of death in sheep in Rio Grande do Sul, Brazil: analysis of 523 cases (2004-2019)

“…Most cases of pneumonia in our study were related to bacterial agents such as Mannheimia haemolytica. Some predisposing factors to bacterial agents in sheep observed in cases of our study are similar to what is described in goats (Bassuino et al 2018) and include stress, low temperatures, transportation, the mixture of animals of different origins, and subclinical haemonchosis. Pneumonia caused by M. haemolytica is characterized as cranioventral lobar or lobular fibrinous bronchopneumonia, foci of coagulative necrosis, and variable fibrinous pleuritis (Caswell & Williams 2016).…”

É possível integrar pecuária à conservação da biodiversidade? Estudo de casos de depredação de ovinos por onça-parda (Puma concolor)

“…Nos principais levantamentos de causas de morte em ovinos (Rissi et al 2010, Almeida et al 2013, caprinos (Rosa et al 2013, Bassuino et al 2018, bovinos (Lucena et al 2010, Rondelli et al 2017) e equinos (Pierezan et al 2009, Marcolongo-Pereira et al 2014 no Brasil; nenhum caso de depredação foi registrado. Nas duas regiões estudadas neste trabalho os casos de depredação de ovinos por onça-parda causaram sérios prejuízos econômicos, evidenciando que as condições ambientais eram favoráveis para os ataques.…”

Patologia De Equinos: Achados Macroscópicos De Equinos Necropsiados Em 2020

“…Nos últimos anos tornou-se frequente estudos das enfermidades que acometem equinos para a determinação de sua frequência e importância econômica (PIEREZAN et al, 2009a), assim como também foram realizados em bovinos (LUCENA et al, 2010), ovinos (RISSI et al, 2010), caprinos (BASSUINO et al, 2018) e suínos (KONRADT et al, 2020). É fundamental o conhecimento das enfermidades que afetam a população equina para que se realize uma determinação econômica e implementação de medidas para controle.…”
