“…A hemoncose foi a enfermidade parasitária de maior frequência em ovinos. Esta parasitose também foi evidenciada em destaque em outros estudos retrospectivos nesta mesma espécie [2,19,26]. Os sinais clínicos característicos de edema submandibular e palidez das mucosas e da carcaça e a visualização de exemplares adultos de Haemonchus contortus na mucosa abomasal à necropsia possibilitaram o diagnóstico desta enfermidade.…”

Background:Knowing the different diseases that affect the herds of a region is a fundamental necessity, because sanity is one of the main factors limiting animal production. Several studies have reported the diseases affecting the animals of various regions of Brazil; however, no such study was carried out in the state of Tocantins so far. Thus, the objective of this work is to report the main diseases diagnosed in cattle and sheep in the central and northern regions of the state of Tocantins, between January 2011 and December 2015. Materials, Methods & Results:The records and reports of the cattle and sheep treated by the clinicians and pathologists of the Ruminants Medical Clinic (SCMR) of the University Veterinary Hospital (HVU), School of Veterinary Medicine and Zootecnia (EMVZ), University Federal of Tocantins (UFT) during the study period were evaluated. The cases were classified into two categories, conclusive and inconclusive; the cases with conclusive diagnosis were classified according to the etiology and the organic systems involved. In the period of five years, 697 cattle and sheep were treated in the SCMR. The diagnoses were made using epidemiological, clinical, and pathological data, and in some cases, using complementary tests. Among the 697 cases reviewed, 692 (99.2%) and 5 (0.8%) cases were diagnosed conclusively and inconclusively, respectively. The most affected system was the digestive system, which accounted for 260 (37.6%) cases; this was followed by the locomotor 130 (18.8%) cases, nervous 56 (8.1%) cases, reproductive 57 (8.2%) cases, urinary 50 (7.2%) cases, skin 16 (2.3%) cases, muscular 11 (2%) cases, respiratory 34 (4.9%) cases, hemolymphopoietic 28 (3.5%) cases, endocrine 24 (3.5%) cases, sense organs 22 (3.2%) cases, and cardiovascular 4 (0.6%) cases. A total of 220 (31.6%) parasitic, 202 (29%) infectious, 106 (15.2%) toxic, 96 (13.8%) nutritional, 52 (7.5%) by physical agents, and 6 (0.8%) congenital/hereditary diseases were identified. Diseases of neoplastic, metabolic, and inconclusive nature represented 15 (2.1%) cases. Discussion: In this study, the most affected organic system was the digestive system. The disturbances of the digestive system in production animals are reported to comprise a group of important diseases, and they are responsible for large economic losses. Parasitic, infectious, and toxic diseases were more frequently diagnosed, a result similar to those of other studies carried out in Brazil. Haemonchosis was the most frequently occurring parasitic disease and occurrence in sheep. The characteristic clinical signs such as submandibular edema and pallor of the mucosa/carcass and the visualization of the abomasal mucosa in adult specimens on necropsy enabled the diagnosis of this disease. The foot injury were the most frequent disease among the others of the infectious order and affected the sheep. Such lesions are characterized by inflammation and ulceration of the skin of the digits, in which numerous bacteria are isolated. The most frequent toxic disorder was bo...

“…A verminose representou 25,71% dos casos diagnosticados em ovinos, 37,5% em caprinos e 11,11% dos atendimentos em bovinos. Estudos prévios colocam a verminose como principal doença infectocontagiosa em pequenos ruminantes [2,10,27,29,32].…”

“…As doenças infecciosas e parasitárias foram as mais diagnosticadas, com prevalências de 30% em bovinos, 29,85% em caprinos e 24,30% em ovinos. O predomínio de doenças infecciosas e parasitárias também foi observado em estudos prévios, tanto de casuísticas hospitalares [6,20,32] como em estudos conduzidos por laboratórios de diagnóstico patológicos [2,10,15,28,29]. Essa alta prevalência é atribuída as falhas de manejo sanitário existentes na produção de ruminantes.…”

were searched in the archives of the Hospital of Veterinary Clinics of UFRGS. Data on species, race, sex, age and diagnosis were collected. Diagnoses were classified as conclusive and inconclusive and the cases with conclusive diagnosis were classified according to etiology: infectious and parasitic diseases, metabolic and nutritional diseases, reproductive and obstetric diseases, toxic diseases, traumatic diseases. The prevalence of diseases and characteristics of ruminants attended (species, sex, category) was calculated. During the study period, between January 2007 and May 2018, 341 ruminants were attended, with emphasis on sheep (42%), goats (39%) and cattle (18%). In addition, a camel with foreign body obstruction, a sambar deer with fracture of the first thoracic vertebra and a buffalo with ruminal impaction were attended. The care profile was mapped, with predominance of females (57%) and adults (59%). Most of the animals did not present a defined breed, but among the breeds stands out Texel, of cutting aptitude, in sheeps and Saanen and Holstein, of dairy aptitude, in goats and cattle, respectively. In the retrospective study, the diseases with infectious and parasitic etiology presented the highest prevalence with 27.5% of the attendances, followed by reproductive (17.5%), traumatic (13.5%), metabolic (10%), others (10%) and toxic (2.5%). Sixty-six animals had inconclusive diagnosis (19.5%). Discussion: The highest prevalences were infectious and parasitic diseases, with emphasis on myiasis and verminosis. So, it is perceived that management corrections are sufficient to reduce the number of occurrences of diseases and prophylactic measures such as vaccination protocol, vermifugation and adequate nutritional management are allied in this walk. Among the reproductive diseases, dystocia (42.85%), which is one of the main causes of mortality in the peripartum period, has been highlighted. Dog attack was the major cause of traumas in ruminants and urolithiasis was highlighted in metabolic diseases. In toxic diseases, copper intoxication was the most important. Sheep are extremely sensitive to this intoxication, as they tend to accumulate copper in the organism. The retrospective study made it possible to visualize the panorama of HCV UFRGS visits to ruminants in the last years, mapping the profile and determining the casuistry of the diseases. Studies of hospital veterinary casuistry are rare, mainly involving ruminants. At the end, it is concluded that studies referring to casuistry are important to know the predominant diseases in a specific area and its risk factors considering differential diagnosis and future prevention programs.

“…Owing to the increase in sheep rearing that focuses on intense weight gain in a short period, animals are subjected to diets that include large amounts of concentrates, which predispose them to several metabolic disorders (SILVA et al, 2009;OLIVEIRA et al, 2015a). In a retrospective study at Mato Grosso do Sul state, pregnancy toxemia and acute ruminal lactic acidosis (ARLA) were the most common metabolic disorders found in sheep (ALMEIDA et al, 2013) Acute ruminal lactic acidosis (ARLA) is caused by the sudden intake of carbohydrates, especially when the rumen environment is not adapted. The ingestion of such diets stimulates rumen fermentation, and consequently, short chain fatty acids (SCFA) and lactic acid are produced that result in pH reduction and increase in rumen osmolarity that may lead to clinical disorders such as hyporexia, ruminal atony and dehydration (BARRETO JÚNIOR et al, 2008;ORTOLANI et al, 2008ORTOLANI et al, , 2010MINUTI et al, 2014;OLIVEIRA et al, 2015b).…”

The aim of this study was to evaluate the effects of two additives (probiotic and monensin) over clinical parameters of sheep submitted to acute ruminal lactic acidosis (ARLA). Eighteen sheeps were divided into three groups of six animals each as follows: probiotic group, supplemented with 4×10 9 CFU/animal/ day of Saccharomyces cerevisiae; monensin group, supplemented with 33 mg of monensin sodium per kg of diet; and control group, without any supplementation. After 30 days of diet (75% of Coast-cross hay and 25% concentrate with 14% of crude protein) and additive intake, ARLA was induced in the all animals by intraruminal administration of 15g of sucrose per kilogram (kg) of body weight. Complete physical examinations to assess the vital signs of the animals were conducted at the following times: baseline (T0), six (T6h), 12 (T12h), 18 (T18h), 24 (T24h), 36 (T36h), and 48 (T48h) hours after ARLA induction. At those times, blood samples were obtained to determine the plasma volume deficit (PVD) and ruminal content for pH measurement. All animals experienced clinical signs of ARLA with ruminal pH lower than 4.9 at T24h. The heart rate and PVD were lower (P < 0.05) in the probiotic group at T36h. Compared to the control and monensin groups, the probiotic group experienced milder ARLA characterized by lower degrees of dehydration and fewer clinical symptoms.Objetivou-se avaliar os efeitos de dois aditivos (probiótico e monensina sódica) sobre a parâmetros clínicos de ovinos submetidos a acidose láctica ruminal aguda (ALRA). Dezoito ovinos foram divididos em três grupos com seis animais cada assim constituídos: Probiótico, suplementado com 4x10 9 ufc/ animal/dia de Saccharomyces cerevisiae; Monensina, suplementado com 33 mg/kg de monensina sódica; Controle, sem aditivo. Após 30 dias de oferecimento da dieta (75% feno de Coast-cross e 25% concentrado com 14% de proteína bruta) e aditivos, os animais foram submetidos à indução de ALRA por meio da administração intraruminal de 15 gramas de sacarose por kg de peso vivo. Foi realizado exame físico completo nos animais com aferição dos parâmetros vitais nos seguintes momentos: basal (T0), seis (T6h), doze (T12h), 18 (T18h), 24 (T24h), 36 (T36h) e 48 (T48h) horas após a indução da ALRA. Em todos os momentos de avaliação foram obtidas amostras de sangue para determinação do déficit de volume plasmático (DVP) e de conteúdo ruminal para aferição do pH. Todos os animais apresentaram quadro de ALRA com pH ruminal menor que 4,9 no T24h, sem diferença entre os grupos (p = 0.092). A frequência cardíaca e o DVP foram inferiores (P<0,05) no grupo Probiótico no T36h. Os animais do grupo Probiótico apresentaram quadro de ALRA mais branda observada por menor grau de desidratação e menor ocorrência de sintomas clínicos em relação aos animais dos grupos controle e monensina.
