The increase in energy imbalance at the beginning of lactation leads to metabolic disorders, especially clinical ketosis, in highly productive dairy cows. The objective of this study is to evaluate the clinical characteristics, biochemical parameters, and cardiac biomarkers creatine kinase MB isoenzyme (CK-MB) and cardiac troponin I (cTnI) of 15 cows diagnosed with clinical ketosis treated at the Bovine Clinic of Garanhuns at the Federal Rural University of Pernambuco. Nine of the 15 cows were diagnosed with primary ketosis and six had concomitant diseases, including left abomasal displacement, metritis, pneumonia, and renal failure. The observed clinical signs were non-specific and included decreased appetite and milk production and weight loss. Approximately 53% of the animals had central nervous system involvement. For biochemical evaluation, 15 high-production healthy dairy cows at the initial stage of lactation served as the control group. The data were subjected to analysis of variance for simultaneous comparison between two means allowing testing the hypothesis on the means of the different groups and subjected to Pearson correlation at a level of significance of 5%. The levels of ?-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), glucose, fructosamine, total protein, albumin, creatinine, aspartate aminotransferase, creatine kinase, CK-MB, and cTnI were higher in the group with ketosis. The diseased animals presented changes in glycemia, reduction in tissue sensitivity to insulin, and a lower RQUICKI-BHB index, especially hyperglycemic animals. The increase in the levels of cardiac biomarkers suggests the occurrence of myocardial injury associated with bovine ketosis.

In order to differentiate groups of hypocalcemic (G1) and normocalcemic animals (G2) and infer the influence of subclinical hypocalcemia on metabolic profiles, this study determined calcium concentrations during the transitional period in 35 dairy goats healthy, pregnant, primiparous or multiparous, crossbreed or pure-bred dairy goats producing average 3 kg/day/goat. Therefore, blood samples were collected before (30, 20 and 10 days before parturition), on the day of delivery and after parturition (10, 20, 30, 40, 50 and 60 days postpartum). The variables measured were glucose, nonesterified fatty acids, β-hydroxybutyrate, cholesterol, triglycerides, amylase, total protein, albumin, urea, creatinine, aspartate aminotransferase, gamma glutamyl transferase, creatine kinase, total calcium, phosphorus, magnesium, chlorides, cortisol and insulin, as well as ionized calcium (Ca++), sodium and potassium. Goats were considered to have subclinical hypocalcemia if Ca++ ≤0.72 mmol/L. The data were analyzed by ANOVA. In subclinically hypocalcemic goats, serum concentrations of Ca++ decreased earlier (10dbp) than in normocalcemic goats (parturition) and remained lower throughout the transitional period (p=0,004). Among the measured variables, Ca++ showed greater influence on the NEFA, glucose, insulin and total calcium but also influenced the protein profile. Lower food intake by goats with subclinical hypocalcemia was one of the main factors interfering with the metabolic profile and likely the productivity of these animals. Studies should be conducted to measure the effects of subclinical disease on the production rates and on the emergence of other transitional period diseases.

Neurological disorders in cattle comprise a group of economically relevant diseases with high occurrence and mortality. In this way, the objective was to carry out an epidemiological study of the diseases with neurological manifestations in cattle admitted (alive or dead) to the Garanhuns Bovine Clinic/Federal Rural University of Pernambuco (CBG/UFRPE) from January 2009 to December 2019. Epidemiological information was collected from the clinical records regarding the age group, rearing system, time of year, and area of origin of the animals. The diseases were grouped into categories according to their origin: toxic or toxi-infectious, viral, traumatic/physical, parasitic, metabolic degenerative, bacterial, neoplastic, and others. A total of 6103 cattle were treated during the study period, of which 604 (10.1%) were diagnosed with diseases that had neurological manifestations. Of these, 331 cases were of single occurrence, and 231 cases occurred as outbreaks in the herd. Death was the outcome in almost 80% of the cases (465/596). The frequencies of the different categories were toxic or toxi-infectious (25.2%), viral (21.5%), traumatic/physical (13.6%), parasitic (9.8%), metabolic (9.3%), degenerative (2.3%), bacterial (2.2%), neoplastic (1.2%), and others (1.2%). It was found that almost half of the animals were older than 24 months (229/475), almost 80% were females, more than 60% were submitted to a semi-intensive to intensive rearing system, and the occurrence of disease was higher during the dry period of the year (363/614). The three most frequent neurological diseases in this study were rabies, trauma, and botulism.

Resumo Objetivou-se estudar a ocorrência das afecções podais em bovinos atendidos na Clínica de Bovinos de Garanhuns, Campus da Universidade Federal Rural de Pernambuco, no intervalo de 1999 a 2021. Realizou-se estudo retrospectivo dos prontuários, com total 334 casos, dos quais foram diagnosticadas 613 lesões digitais. Foi realizada a distribuição de frequência, média simples e desvio padrão para avaliação dos dados. A dermatite interdigital foi a mais frequente, sendo observada em 12,4% (76/613) dos casos, seguida por sola dupla 9,79% (60/613), laminite crônica 8,81% (54/613), úlcera de sola 7,83% (48/613) e a hiperplasia interdigital 7,24% (45/613). A laminite e suas consequências representaram 45% do total de lesões identificadas, acompanhadas por 36% das injúrias de causa secundárias ou incertas e de doenças infecciosas com 19%. A distribuição das lesões entre os membros foi de 68% nos pélvicos e 32% nos torácicos. As fêmeas criadas em sistema semi-intensivo, holandesas, com escore corporal III e porte grande eram mais acometidas. A claudicação estava presente em 78% dos animais, enquanto 10% não claudicavam. As taxas de letalidade e recuperação foram de 9% (31/334) e 73 % (243/334), respectivamente. No período chuvoso foram 51% dos casos e 49% na época seca. Os principais municípios de origem foram Bom Conselho 22,75% (76/334), Garanhuns 18, 86% (63/334) e Brejão 12,57% (42/334). O custo estimado com tratamento foi de US$ 150,13/caso. Provavelmente falhas de manejo nas propriedades foram importantes fatores de risco para as doenças. Sugere-se a implementação de medidas profiláticas para evitar as perdas econômicas associadas às enfermidades podais.

This study aimed to carry out a retrospective study of vagal indigestion cases diagnosed in cattle admitted at the Garanhuns Bovine Clinic, Federal Rural University of Pernambuco campus. This syndrome, caused by dysfunctions of the vagus nerve and characterized by motility disorders of the pre-stomachs and abomasum, represented 5.5% (70/1279) of digestive cases diagnosed in a period of 10 years and had an unfavorable prognosis in 78.3% of cases. Type II vagal indigestion was the most prevalent, accounting for 40% of cases, followed by type I (24.3%) and types III and IV, which accounted for 18.6% and 10.0% of cases, respectively. Vagal indigestion in 67.1% (47/70) of cases occurred as a result of other illnesses, such as traumatic reticuloperitonitis (27.7%), lung diseases (12.8%), gastric impaction (10.6%), abomasal ulcer (10.6%), lymphosarcoma (6.4%), and liver abscesses (6.4%). Motor changes in the gastrointestinal tract, such as hypomotility, abdominal distension, and bloat, as well as their consequences, were the most frequent clinical signs. Laboratory, ultrasonographic, and anatomopathological alterations mainly originate from the primary illnesses present in each case. The approach of this disease is essential due to its clinical and economic importance for livestock to expand the knowledge of its etiopathogenesis, thus contributing to a more accurate diagnosis by veterinarians working in the field of internal medicine for cattle. Objetivou-se realizar um estudo retrospectivo dos casos de indigestão vagal diagnosticados em bovinos atendidos na Clínica de Bovinos de Garanhuns, campus da Universidade Federal Rural de Pernambuco. Essa síndrome, causada por disfunções do nervo vago e caracterizada por transtornos de motilidade dos pré-estômagos e abomaso, representou 5,5% (70/1279) dos casos digestivos diagnosticados num período de 10 anos e apresentou prognóstico desfavorável em 78,3% dos casos. A indigestão vagal tipo II foi a mais prevalente, representando 40% dos casos, seguida do tipo I (24,3%) e dos tipos III e IV, que corresponderam a 18,6% e 10,0%, respectivamente. Em 67,1% (47/70) dos casos, a indigestão vagal ocorreu em consequência de outras enfermidades, tais como reticuloperitonite traumática (27,7%), doenças pulmonares (12,8%), compactação gástrica (10,6%), úlcera de abomaso (10,6%), linfossarcoma (6,4%) e abscessos hepáticos (6,4%). As alterações motoras do trato gastrointestinal, tais como hipomotilidade, distensão abdominal e timpania, assim como suas consequências foram os sinais clínicos mais frequentes. As alterações laboratoriais, de imagem e anatomopatológicas são oriundas principalmente das enfermidades primárias presentes em cada caso. Devido sua importância clínica e econômica para a bovinocultura, é primordial a abordagem dessa enfermidade, visando ampliar o conhecimento da sua etiopatogenia contribuindo dessa forma para um diagnóstico mais preciso pelos médicos veterinários atuantes na área de medicina interna de bovinos.

Resumo Os distúrbios neurológicos em bovinos abrangem um grupo de enfermidades economicamente relevantes de elevada ocorrência e mortalidade. Desta forma, objetivou-se realizar um estudo epidemiológico das enfermidades que cursaram com manifestações neurológicas que deram entrada (vivos ou mortos) na Clínica de Bovinos de Garanhuns/Universidade Federal Rural de Pernambuco no período de janeiro de 2009 a dezembro de 2019. Nos prontuários clínicos, foram coletadas informaçõe epidemiológicas referentes ao sexo; a faixa etária; ao sistema de criação, época do ano e a área de procedência dos animais. As doenças foram agrupadas em categorias de acordo com sua origem: tóxica ou toxi-infecciosa, viral, traumática, parasitária, degenerativa, metabólica, bacteriana, neoplásica e outras. Um total de 6103 bovinos foram atendidos no período estudado, dos quais 604 (10,1 %) foram diagnosticados com enfermidades que cursaram com manifestações neurológicas. Destes, 331 casos foram de ocorrência individual, 231 casos cursaram como surtos no rebanho. Quase 80% dos casos (465/596) teve o óbito como desfecho. As frequências das distintas categoria foram tóxica ou toxi-infecciosa (25,2%), viral (21,5%), traumática/física (13,6%), parasitária (9,8%), metabólica (9,3%, degenerativa (2,3%), bacteriana (2,2%), neoplásica (1,2%), outras (1,2%). Verificou-se que quase metade dos animais apresentavam idade superior a 24 meses (229/475), quase 80% eram fêmeas, mais de 60% eram submetidos a um sistema de criação de semi-intensivo a intensivo e a ocorrência foi maior durante o período seco do ano (363/614). As três enfermidades com manifestações neurológicas de maior ocorrência neste estudo foram a raiva, os traumatismos e o botulismo.
