Full textEste trabalho pretende ser um resumo do que na actualidade se debate a nível científico e clínico acerca da fisiopatologia, diagnóstico, tratamento, prognóstico e prevenção de uma patologia muito grave e ainda muito pouco compreendida como é a laminite em equinos. Sendo uma patologia algo frequente e debilitante, com prognóstico de reservado a mau, e embora existam há muitos anos tentativas da comunidade científica em explicar a laminite, de maneira a melhorar o tratamento e a prevenção, estes estudos têm sido muitas vezes contraditórios. Apesar de ter já existido uma grande evolução no estudo desta patologia no entanto o factor desencadeante não foi ainda comprovado cientificamente apesar de existirem algumas teorias a seu respeito. Serão apresentados dois casos clínicos que ocorreram durante o meu período de estágio, com os quais me apercebi não só das dificuldades atrás referidas mas também de outras associadas à clínica de equinos em Portugal, sendo a mais visível a vertente económica.

Full textA Osteoartrite (OA) é a principal causa de claudicação no cavalo de desporto e lazer, sendo uma afecção que tem grandes repercussões económicas. Este trabalho descreve algumas das características importantes da estrutura articular, bem como da sua fisiologia. Define a OA e todas as estruturas envolvidas no seu processo. Os mecanismos fisiopatológicos põem em evidência os factores de risco em causa e que determinam todo o processo de degradação articular. São descritos os vários meios de diagnóstico utilizados, quer os convencionais, quer as recentes técnicas imagiológicas (ressonância magnética, tomografia computadorizada e cintigrafia nuclear) quer ainda os biomarcadores do metabolismo da cartilagem articular e osso. A abordagem terapêutica é diversa incluindo os anti-inflamatórios não esteróides, os corticosteróides, os glicosaminoglicanos polisulfatados, o hialuronato de sódio, o pentosan polisulfato e o ácido tiludrónico, com o objectivo de travar a progressão da doença articular. Também são abordadas novas formas alternativas de tratamento da OA, como a terapia por meio de ondas de choque, a utilização de células estaminais mesenquimatosas e a terapia genética. Este trabalho é complementado pela descrição de dois casos clínicos, onde são abordados o diagnóstico e respectivo tratamento.
ABSTRACT - The Osteoarthritis (OA) is the main cause of lameness in the sport and leisure horse, being an affection with great economic evolvement. This work describes the main characteristics of the joint structure, as well as its physiology. It defines the OA and all the involved structures in its process. It’s physiopathology puts in evidence all the risk factors and all the process of joint degradation associated. Diagnosis methods are mentioned, not only the conventional ones, but also the recent imaging techniques (magnetic resonance imaging, computed tomography and nuclear scintigraphy) and the use of the bone and cartilage biomarkers. Diverse types of treatment are used, as it is the case of non-steroidal anti-inflammatory, corticosteroids, polysulfated glycosaminoglycan, hyaluronan, pentosan polysulfate and acid tiludronic, drugs, achieving to decrease the progression of the joint disease. Also new forms of treatment of the OA are referred as the therapy using shock waves, mesenchymal stem cells and the gene therapy. Two clinical cases are described, where the diagnosis and treatment are boarded.

Sete equinos hígidos, de ambos sexos, foram utilizados para este experimento, com objeto de avaliarmos as diferenças de temperatura do casco do animal, antes e após o ferrageamento a quente, com auxílio de termógrafo infravermelho, por duas avaliações com intervalo de 45 entre elas. O teste t de Student pareado foi escolhido para análise estatista, e foram considerados valores significativos para diferentes momentos do ferrageamento quando p<0,05. Houve diferença significativa de temperatura em quase todas imagens realizadas do casco quando comparadas as temperaturas anteriores e posteriores ao ferrageamento a quente. Embora as temperaturas tenham se elevado após ferrageamento, este aumento não ultrapassou a temperatura corpórea fisiológica (37,5ºC-38,5ºC). Não houve danos ao estojo córneo como linhas de estresse e rachaduras. Não houve falha no crescimento do casco entre os ferrageamentos. Os animais não manifestaram dor, e tão pouco alteram o comportamento durante o procedimento. Os parâmetros vitais não apresentaram diferença significativa entre os momentos. Por estes resultados, é possível aventar que o ferrageamento a quente é uma prática segura e não causa danos ao casco.
Thermography has been widely used in veterinary medicine, mainly in diagnostic, prognostic and preventive aid. The aim of this study was to observe the temperature of toracic hooves, the anterior limbs, before and after the hot fitting, with the help of a thermograph, to establish a temperature pattern after the shoeing and to infer if it can cause damages to the hoof equine. Although the forged horseshoe reaches very high temperatures, the hoof temperature rise did not exceed physiological temperature values. Based on the maintenance behavior during the procedure, maintenance of the normal values in the physical examinations and with the conservation of the hoof growth, between one shoeing and another, it is possible to infer that the hot fitting is a safe practice and does not cause damage to the hoof.

Full textIn order to evaluate the effect of supplementation with gamma-oryzanol in horses undergoing aerobic exercise were used ten Purebred Arabian horses, geldings, mean age 35±8.15 months and mean weight of 375±22.78 kg at the beginning of the experimental period, divided into two groups of five animals each, named \"gamma\" and \"control\" groups. The experiment was conducted at the Laboratório de Pesquisa em Alimentação e Fisiologia do Exercício de Equinos (LABEQUI), belonging to FMVZ-USP, at Campus Administrativo de Pirassununga, São Paulo, adopting individual daily consumption of 2% of body weight, based on dry matter, 50% of forage composed of grass hay and 50% commercial concentrate. In each meal, the animals received fifty milliliters of vegetable oil, and only the gamma group received the gamma-oryzanol (ten grams daily). Both groups were trained in electronic walker for sixty minutes at a maximum speed of 12 km/h, five times a week. During the trial period of six months, the horses were evaluated monthly to weight gain, body condition score, and plasma lipids (total cholesterol and HDL-C, VLDL-C, LDL-C, and triglycerides). The every fortyfifth days were performed ultrasonographic measurements of the thickness of muscle and adipose Longissimus dorsi, and the thickness of the fat layer at the insertion of the tail. We obtained heart rates (HR) at baseline, during maximal work (HR peak), final HR and HR at 10 and 20 minutes after the end of the exercise. We used a completely randomized design with repeated measures and significance level was 10 %. In relation to body weight or measure ultrasound there was no difference between the groups, but was observed reduction of body condition score, reducing over time (p=0,04) of 10 % for the gamma group when compared with the control group (6.5 %). The total cholesterol concentration was higher (p=0.001) for the gamma group (113.99 mg/dL) than the control group (108.55 mg/dL). Regarding the heart rate (HR) effects were observed over the time baseline HR (p=0.001), final (p=0.003), and at the end of exercise after 10 (p < 0.001) and 20 (p = 0.009) minutes. The HR after 20 minutes also showed interaction time*treatment (p=0.05) , the gamma group had lower average (46.03 bpm) than the control group (46.21bpm) , and over the 180 days the average this variable reduced by 30 % for the gamma compared to control group (7 %). Supplementation with gamma-oryzanol in horses undergoing aerobic exercise can provide a reduction of body condition score, raising the concentration of plasma cholesterol and can improve heart rate recovery after exercise.

A doença do navicular, osteíte podal e a laminite estão entre as enfermidades de maior incidência em equinos, sendo todas elas citadas como afecções de origem vascular. A fotopletismografia é um método diagnóstico não invasivo que quantifica o tempo de reenchimento venoso baseado na circulação periférica terminal. Objetivou-se estudar a exequibilidade e viabilidade da fotopletismografia podal em equinos, padronizando os valores normais para a espécie. Foram utilizados 10 equinos hígidos, avaliando-se os membros torácicos em diferentes superfícies, sendo dividos em dois grupos: Grupo Borracha (GB) e Grupo Concreto (GC). A fotopletismografia foi realizada com os animais em posição quadrupedal, realizando-se movimentos pendulares para mimetizar movimentos de apoio e elevação do membro, realizando-se cinco movimentos consecutivos e então, imediatamente induzidos ao repouso, obtendo-se então, o tempo de reenchimento venoso (TRV). Não houve diferença significativa entre o membro torácico direito e membro torácico esquerdo nos diferentes grupos (p=0,75). A média do TRV nos equinos do grupo borracha (GB) foi de 12,650 ± 1,694 e no grupo concreto (GC) foi de 12,700 ± 1,387 segundos, não demonstrando diferença significativa entre os diferentes pisos (p=0,98).

Abstract: The thoracic limb disorders are the major cause of the musculoskeletal changes affecting the horses. Navicular disease, foot osteitis and laminitis are among the diseases of higher incidence in equines, all of which are cited as affections of vascular origin. Photoplethysmography is a noninvasive diagnostic method that quantifies venous refill time based on the terminal peripheral circulation. The objective is study the feasibility of foot photoplethysmography in horses, standardizing the normal values for this species. Thoracic limbs were used on different surfaces and divided into two groups: Rubber Group (RG) and Concrete Group (CG). The photoplethysmography was performed with the animals in a quadrupedal position, with pendular movements being performed to mimic support and elevation movements. Five consecutive movements were performed, and then immediately induced at rest, and venous refilling time (VRT). There was no significant difference between the right and left thoracic limbs in the different groups (p=0.75). The mean TRV in the horses of the rubber group (GB) was 12.650 ± 1.694 and the concrete group (CG) it was 12.700 ± 1.387 seconds, showing no significant difference between the different floors (p=0.98). The reference values in horses are different in relation to human patients. It can be concluded that the photoplethysmography of the thoracic limbs in horses can be used as an auxiliary method to evaluate the microcirculation of the foot, the reference value fo...

Full textO termo “cólica” é referente a um conjunto de manifestações de dor abdominal, geralmente com origem ao nível do tracto gastrointestinal ou, menos frequentemente, em outras estruturas localizadas no interior do abdómen. Embora nem sempre seja possível estabelecer um diagnóstico, as causas mais frequentes parecem ser as obstruções simples. Além disso, os quadros de cólica são muitas vezes moderados, resolvendo-se espontaneamente ou necessitando apenas de uma intervenção terapêutica. No entanto, trata-se de uma das entidades clínicas mais importantes na medicina equina, não só pela sua prevalência como também pelas suas consequências. De facto, e apesar dos meios de diagnóstico e tratamento actualmente disponíveis, a cólica pode acarretar prejuízos económicos avultados para os proprietários, para além do respectivo envolvimento afectivo. Assim, é importante que o prognóstico seja o mais exacto possível, uma vez que é fundamental para a tomada de decisões sobre a gestão de cada caso clínico. Nesse sentido, têm vindo a ser realizados numerosos trabalhos com o intuito de utilizar as informações recolhidas durante o exame clínico para melhorar a capacidade de o médico veterinário estabelecer um prognóstico. De entre todos os parâmetros que têm sido estudados, os que mais frequentemente apresentam uma associação com o desfecho dos casos de cólica são aqueles que reflectem a condição cardiovascular. O presente trabalho teve como principal objectivo apresentar os factores de prognóstico da cólica em equinos que têm vindo a ser referidos na literatura, bem como estudar a importância de alguns deles numa amostra da população compreendendo 20 casos de cólica com origem ao nível do tracto gastrointestinal (incluindo a peritonite). Através da análise dos resultados obtidos, foi possível constatar que, comparativamente com os cavalos sobreviventes, aqueles que morreram apresentaram um grau de dor e um tempo de repleção capilar mais elevados, uma coloração anormal das mucosas e uma motilidade intestinal mais reduzida. Além disso, verificou-se que a temperatura rectal, a frequência cardíaca e a concentração sanguínea de glucose elevadas, bem como a presença de uma baixa concentração plasmática de proteínas totais, estavam associadas a um prognóstico desfavorável. Embora não tenham sido encontradas diferenças significativas entre os grupos de desfecho no que respeita à concentração sanguínea de lactato, os resultados obtidos revelaram uma grande proximidade em relação ao nível de significância considerado, tendo-se registado valores superiores para este parâmetro no grupo dos não sobreviventes.
ABSTRACT - Prognostic factors in equine colic - The word “colic” often refers to a particular set of manifestations of abdominal pain that are frequently related with the gastrointestinal tract or, to a lesser extent, with other structures located in the abdomen. The more frequent causes seem to be related with simple obstructions, although it is not always possible to establish a diagnosis. Also, the clinical boards associated with colic often present themselves as moderate and tend to self-resolve or need simple therapeutic intervention. Nevertheless, this is one of the most important clinical subjects in equine practice not only due to its wide spread occurrence, but also because of its consequences. In fact, and despite all the diagnosis techniques currently available and the continuous evolution in treatment, colic related problems tend to result in large expenses for the owners, as well as affective issues concerning personal loss. It is therefore important that the prognosis is as accurate as possible since it plays a key role in all the decisions that need to be taken and in the management of each clinical case. Numerous research efforts have thus been undertaken with the goal of using the information gathered during the clinical examination to improve the veterinarian’s ability to establish a prognosis. Of all the parameters that have been studied, those that are more often associated with the outcome are the ones that reflect the patient’s cardiovascular status. The present study sets its main goal in presenting the colic prognostic factors referred to in the literature, and to study the importance of some of them in a sample of 20 horses with colic of gastrointestinal origin (also including peritonitis). The analysis of the results enabled to conclude that in comparison with the survivors, the non survivors presented higher severity of pain and capillary refill time, abnormal mucous membranes colour, and reduced intestinal motility. Also, higher rectal temperatures, heart rates and blood glucose concentrations, and lower plasma total protein concentrations, were found to be associated with worse prognosis. Although no significant differences have been found within the two outcome groups for the blood lactate concentration, the results revealed only a slight difference to the considered significance level, and higher values of this parameter were found for the non survivors.

Nosso estudo avaliou as características biomecânicas (comprimento e frequência da passada, deslocamento dorsoventral, potência dorsoventral, propulsão, potência médio lateral e potência total) de potros da raça Mangalarga Marchador, comparando com os melhores animais adultos da propriedade com o objetivo de identificar precocemente características desejáveis da marcha. Foram avaliados doze potros nos primeiros quinze dias de vida e dez adultos, em uma mesma propriedade. A obtenção das variáveis cinemáticas e cinéticas foi realizada com o equipamento de análise de andamento Equimetrix (Centaure Métrix, Fontainebleau, France) e a velocidade acompanhada com uso de GPS preso no braço do treinador. Foi realizada a comparação dos dois grupos, ao passo e à marcha. Nossos resultados demonstraram que ao passo podem ser observadas precocemente nesta raça a frequência e a simetria desde o nascimento e a regularidade a partir do décimo primeiro dia de vida. Em relação à marcha, a regularidade foi o único parâmetro consistente desde o nascimento
The aim of this study was to compare the biomechanical characteristics of gait (length and frequency of the gait, dorsoventral displacement, dorsoventral power, propulsion, lateral power mean and total power) of foals and adult animals from Mangalarga Marchador breed to identify early characteristics of gait. Twelve foals were evaluated during the first 15 days of life and the results were compared to the mean values recorded from 10 adult horses. Kinematic and kinetic variables were obtained with Equimetrix (Centaure Métrix, Fontainebleau, France), and speed was monitored using a GPS attached to the trainer's arm. Step and marcha gait analyses were compared between groups. At walk, our results demonstrated that frequency and symmetry are similar to adults and can be observed early in foals since the day of birth whereas regularity is characteristic for this breed from the 11th day of life on. Regarding gait, regularity was the only consistent parameter since birth

Devido à característica e ao envolvimento vascular da pododermatite asséptica, a compreensão das ocorrências vasculares dentro do casco passou a ser o foco dos trabalhos científicos. A venografia começou a ser utilizada para este fim. É um método de diagnóstico por imagem minimamente invasivo, prático e essencial para acessar a circulação digital. Auxilia, portanto, médicos veterinários e ferradores na escolha da terapêutica apropriada para a restauração da circulação do digito; possuindo acurado valor prognóstico. No presente trabalho, para o estudo venográfico dos cascos de membros torácicos, foram utilizados 19 equinos com idade média de 9,5 ± 4,4 anos, 12 machos e 07 fêmeas, sendo 11 animais com ausência de sinais clínicos de claudicação e 08 apresentando grau de claudicação de apoio, variando de 1 a 4/5, de acordo com método proposto pela AAEP. O objetivo do trabalho foi avaliar venogramas dos dígitos de animais claudicantes e não claudicantes, a partir da criação de escala semi-quantitativa de preenchimento por contraste radiográfico, nas seguintes regiões: arco terminal, vasos laminares dorsais a falange distal, plexo coronário, vasos circunflexos e bulbo do talão. Os dados obtidos foram submetidos à análise estatística ANOVA, complementados por TUKEY, com nível de significância p < 0,05 para comparação entre todos os grupos (membro torácico esquerdo de animais não claudicantes, membro torácico direito de animais não claudicantes, membro torácico esquerdo de animais claudicantes e membro torácico direito de animais claudicantes). Obteve-se diferença estatística entre os venogramas dos animais claudicantes e não claudicantes, não importando o membro torácico utilizado para a análise. Isso significa dizer que o animal com deficiência de apoio apresenta menor perfusão do dígito. Quanto as regiões observadas, a diminuição de irrigação se fez presente com maior frequência no arco terminal, nos vasos circunflexos e nos vasos laminares dorsais.
Due to the characteristic and vascular involvement of aseptic pododermatitis, the understanding of vascular occurrences within the foot became the focus of scientific work. The venography began to be used for this purpose. It is a minimally invasive, practical and essential diagnostic imaging method to access the digital circulation. It assists, therefore, veterinarians and farriers in the choice of the appropriate therapy for the restoration of the circulation of the digit, having an accurate prognostic value. In the present research, 19 horses with a mean age of 9.5 ± 4.4 years,12 males and 07 females, were used for the venography study of the foot of the forelimbs, of wich 11 without clinical signs of lameness and 08 presented a degree of claudication of support, varying from 1 to 4/5, according to the method proposed by the AAEP.The purpose of this study was to evaluate the venograms of the digits of both, claudicating and nonclaudicating animals, from the creation of a semi-quantitative scale flilled by radiographic contrast data, of the following regions: terminal arch, dorsal laminar vessels to the distal phalanx, coronary plexus, circumflex vessels and heel perfusion. The gathered data were submitted to ANOVA statistical analysis, complemented by TUKEY, with significance level p <0.05 for comparison between all groups (left thoracic limb of non-claudicating animals, right thoracic limb of non-claudicating animals, left thoracic limb of claudicating animals and right thoracic limb of claudicating animals). There was a statistical difference among the venograms of the claudicating and non-claudicating animals, regardless of the thoracic limb used for the analysis. This means that the animal with a support deficiency has lower perfusion of the digit. Regarding the regions observed, the decrease of irrigation was more frequently present in the terminal arch, circumflex vessels and dorsal laminar vessels.

Full textRESUMO: Objetivou-se avaliar o efeito da suplementação de levedura Saccharomyces cerevisiae na dieta de equinos senescentes e seus efeitos sobre o desempenho e coeficientes de digestibilidade aparente de nutrientes. Foram utilizados 18 equinos machos castrados, sem raça definida, com peso médio 426,167±25,3kg e idade média de 17,5±1,42 anos. Os tratamentos consistiram na utilização de diferentes fontes de leveduras adicionados a 200g de concentrado, sendo: tratamento controle - sem adição de levedura (10mL meio de cultura estéril); tratamento contendo a levedura Saccharomyces cerevisiae, UFMG 905 na concentração de 3x108 UFC/mL/dia; e o tratamento contendo probiótico comercial composto por Lactobacillus casei >7,9x104UFC/mL, Lactobacillus acidophilus >7,9x104UFC/mL e Saccharomyces cerevisiae >1,5x106UFC/mL. A dieta padrão foi composta por concentrado comercial e feno Tifton 85 (Cynodon spp) na proporção de 30:70, respectivamente. O experimento teve a duração de 31 dias, sendo 28 dias de adaptação e três dias para o ensaio de digestibilidade. Foi avaliado o desempenho dos animais por meio do peso, consumo de concentrado, de volumoso e da dieta total. Para determinação dos coeficientes de digestibilidade foi utilizado o método de coleta total de fezes. O isolamento de microrganismos Lactobacillus spp. usou-se a contagem direta em placas. O delineamento foi inteiramente casualizado, sendo três tratamentos e seis repetições, considerando o animal a unidade experimental. Os dados foram analisados por meio da ANOVA e teste Dunnet, considerando 5% de significância para as variáveis de desempenho e 10% para os coeficientes de digestibilidade. O peso final, consumo de concentrado, volumoso e dieta total não diferiram entre os tratamentos (P>0,05). Entretanto, houve aumento do peso (P=0,03) e maior ganho de peso (P=0,03) nos animais suplementados com a levedura UFMG 905. A matéria orgânica, extrato etéreo, fibra em detergente neutro, fibra em detergente ácido e teor de carboidratos não estruturais não diferiram entre os tratamentos (P>0,10). Entretanto, os coeficientes de digestibilidade da matéria seca (P=0,05) e da proteína bruta (P=0,10) foram maiores no tratamento comercial em relação ao controle e o coeficiente de digestibilidade da hemicelulose foi reduzido (P=0,01) no tratamento comercial em relação ao controle, o crescimento bacteriano nos tratamentos UFMG905 e comercial foram semelhantes entre si com elevação de 106 para 107 ufc/g. Em conclusão, a suplementação de probiótico contendo Saccharomyces cerevisiae em dietas para equinos acima de 16 anos, aumentou o ganho de peso, a digestibilidade da matéria seca e da proteína bruta e favoreceu um crescimento de Lactobacillus spp., podendo ser utilizado como probiótico. Mais estudos são necessários no sentido de definir concentrações ótimas de leveduras e seus efeitos em equinos.

Full textThe aim of this study was to analyze free type 1 insulin-like growth factor (IGF1) and insulin (INS) concentrations in follicular fluid during folliculogenesis in mares, and to localize type 1 IGF receptor (IGF1R) on follicular walls. During the breeding season, 40 mixed-breed mares sent to slaughter at an abattoir, with ages ranging between 6 to 16 years were used. Mares were humanely slaughtered. Internal reproductive tracts were recovered within 10 min after slaughter; ovaries of cyclic mares were separated from the rest of the tract. Mares were categorized into four groups: G1 – Follicle ≤ 13.5 mm and CL identifiable; G2 – Follicle of 13.6 to 22.5 mm and CL identifiable; G3 – Follicle of 22.6 to 31.5 mm and CL identifiable; G4 – Follicle ≥ 31.6 mm and CL difficult to identify. The follicular fluid (FF) was aspirated and stored at -80°C until use. After puncture of the FF, a fragment of the ventral portion of the follicular wall was removed to perform immunohistochemistry to localize IGF1R receptors. Free IGF1 was determined by immunoradiometric assay. INS was determined by a liquid phase radioimmunoassay. The concentration of free IGF1 and INS in FF increased with follicle growth (P < 0.05). Immunohistochemical score of IGF1R on granulosa and internal theca cells from equine follicular wall on different groups increase (P < 0.05) with follicular raise. We conclude that free IGF1 and INS concentrations in FF and IGF1R in follicular walls of mares increase with follicular growth during folliculogenesis, giving evidence of important role of IGF1 and INS in follicular development, and an interaction between both hormones in ovarian reproductive physiology. As the mare is a model research for comparative studies in follicular dynamics for consideration in women, the conclusion of this study can be applied to humans also.

Full textCurrently, the evaluation of training and nutrition for sport horses, has been widely studied in order to achieve maximum performance of sport horses in competitions. The body composition of muscle and fat deposition, as well as in humans, is one of the best indicators of performance. The body condition score (BCS) is a subjective indicator of body condition in horses, based exclusively on fat deposition. Ultrasonography has proved to be a valuable tool in the evaluation. In order to study the relationship score with measures of body fat and muscle thickness obtained by ultrasonography in three distinct races, we used 14 Thoroughbred horses (PSI), 7 Quarter Horses (QM) and 10 Purebred Arabian horses (PSA) with a mean age of 3.5 ± 0.5 years and average weight of 471 kg. Os animals were evaluated by ultrasonography in three regions parallel to the spine, back fat thickness (EGL ), thickness of gluteal muscle (EMG) and fat thickness in tail (EGC). the measurements were performed every 30 days for 60 days. The results showed a different behavior between the races, but the correlation of scores with a measure of body fat thickness at the head of the tail (EGC), had a higher correlation, compared with the other variables Ultrasonographic evaluation proved to be a reliable and practical tool for assessing body condition of horses in sport horses.

Full textChanges in feed for horses led to change also the natural tooth wear, making it cluttered and even inefficient, contributing broadly to digestive disorders. The aim of this study was to investigate the implications of dental treatment on the digestive and metabolic parameters of horses. Eight horses, Arabian race, castrated male, mean age 80 ± 7 months and average weight of 460 ± 28 kg never undergoing dental treatment were used. The animals were housed in individual stals, fed a diet consisting of 2% of body weight (BW) in MS/day, divided into 0.75% of pelletized concentrate formulated for equine maintenance and 1.25% grass hay ( Cynodon sp. cv. Tifton 85). The treatments were divided into control group (D0; animals without any dental treatment), D20 group (animals evaluated twenty days after dental treatment) and D40 group (animals evaluated forty days after the dental treatment). The animals went through a period of adjustment to the 15-day diet and five days of total collection. The floating teeth consisted of sedation and, as a result, reduction of excessive enamel points and occlusion adjustment, seeking to improve the range of masticatory movements. The variables evaluated were: apparent digestibility coefficient (CD) of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP) and ether-extract (EE); area under the curve (AUC) of glucose and insulin, ingestive behavior, cholesterol, triglycerides, and lipoproteins concentration, fecal pH, short chain fatty acids (SCFA) and lactic acid in the stool. The experimental design was completely randomized with repeated measures time, and data were submitted to analysis of variance considering a 5% significance. There were differences in apparent digestibility (P<0.05) with reduction in the ADF in D20 and D40 groups. For SCFA profile, floating teeth increased propionic acid D40 group compared to the control and reduction of lactic acid in the feces of the D40 group compared to the control. The animals of group D40 had weight reduction (P<0.05). The odontoplastia did not interfere in the remaining parameters. It can be concluded that after floating teeth there were changes in voluntary intake of roughage, which promotes change in concentrate/roughage diet of horses, interfering in the fermentation environment and postprandial metabolic.

Full textThe biologic behavior of a rabies virus recently isolated from an equine raised at a region neighbor to São Paulo, Southeast Brazil, the isolate M82-02, was studied in mice by inoculating through intracerebral and intramuscular route, for evaluation of characteristics related to its infectivity, pathogenicity, incubation period and course of clinical illness and also the virus capacity to invade other non-nervous tissues. The first intracerebrally passaged mouse brain was submitted for antigenic typing by using a set of monoclonal antibodies (MABs) prepared at the Canadian Food and Inspection Agency, Ottawa, Canada, and it was found to be a variant of vampire-bat related rabies virus. After extraction of genetic material, the sample was characterized genetically at the National Institute of Infectious Diseases, Tokyo, Japan, ant the isolate belonged to genotype 1 of the Lyssavirus gene, closely related to the Vampire-bat related virus group-VRRV, common among the Brazilian rabies virus isolates from herbivores and vampire bat Desmodus rotundus. The successive intracerebral and intramuscular passages in mice provoked a slight increase in the virus titer, and the stabilization of the incubation period. In its 10th passage, the isolate was used as the antigen in mouse serum neutralization test, for the assessment of equine sera which had been vaccinated with a commercial PV rabies inactivated virus vaccine, the equine sera were tested in parallel with the CVS strain and some sera were found with neutralizing titer >0.5 IU/mL. Using the isolate M82-02 of rabies virus as an antigen in the neutralization test, no significant difference could be detected, when the results were compared to that of the CVS strain. By means of direct fluorescent antibody (dFA) test, the presence of rabies virus antigen was detected in tissues of brain, lung and kidneys of mice inoculated by intramuscular route, especially in serially passaged materials. The CDC-potency test for evaluation of a commercial vaccine using the field isolate M82-02 as a challenge virus showed a poorer result than the challenge with the fixed CVS strain, however, this method needs further modifications for the routine use.

Were used eight animals, Mini-horse breed, geldings, aged 42±6 months, average weight 135±15 kg, fed a diet containing high relation concentrate:roughage, consisting of 60% commercial concentrate and 40 % of grass hay, which variation was the inclusion of essential oil containing 7% carvacrol, with the treatments divided according to the level of inclusion: 0 (control), 100, 200 and 300 ppm. The experimental design was 4x4 latin square with repeated measures over time and the data were subjected to analysis of variance with a significance level of 5%. The results of the digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF) and acid deterge nt fiber (ADF) were, respectively, P=0.48; P=0.66; P=0.58; P=0.64; P=0.55; P=0.58 and P=0.46. Faecal pH values were found suitable (pH=6.38) to the balance of microorganisms, and there was no effect of treatment (P=0.84). In evaluation of the area under the curve (AUC), weren´t observed effects of treatment (P=0.48) values for glucose. The response of plasma insulin showed a quadratic effect for AUC (P=0.05) in times 90, 150 and 210 minutes.

Full textNa espécie equina a placenta é do tipo epiteliocorial, o que impossibilita a passagem de anticorpos para o feto durante a gestação. A transferência de imunidade depende integralmente da ingestão e absorção intestinal das imunoglobulinas (Ig) maternas veiculadas pelo colostro, nas primeiras 24 horas de vida. As infecções neonatais devem-se, principalmente, à falha na transferência passiva de imunidade (FTPI), que tem como principais causas a lactação prematura, a produção de colostro de fraca qualidade ou em reduzida quantidade e a incapacidade de ingestão de colostro ou falha/anomalia na absorção intestinal de Ig. O principal objectivo deste trabalho consistiu na avaliação de factores que influenciam a transferência passiva de imunidade (TPI), através da determinação das concentrações de IgG e Proteína Total (PT) no soro de éguas, no dos respectivos poldros e no colostro (antes e após a sua ingestão). Foi determinada a densidade do colostro com o auxílio de um colostrómetro, a concentração de PT pelo método de Bradford e o teor de IgG por cromatografia por afinidade (High Performance Liquid Chromatography). Paralelamente, no pós-parto foram avaliados os parâmetros vitais do poldro com vista à determinação da sua categoria de risco, tendo-se verificado posteriormente a sua correlação positiva com o seu nível sérico de IgG. Nas amostras de colostro recolhidas após ingestão, e considerando a variável tempo decorrido desde o parto, verificou-se um decréscimo significativo do rácio IgG:PT. Não se verificou a existência de correlação entre o nível sérico de IgG na égua e no respectivo colostro, assim como entre o colostro e os níveis séricos nos poldros em que se verificou prévia ingestão. Contudo, o nível sérico de IgG na égua parece influenciar positivamente o respectivo nível sérico nos poldros que ingeriram colostro. Foram encontrados níveis séricos de IgG mais elevados em poldros que ingeriram colostro relativamente aos que não ingeriram, o que confirma o importante papel do colostro na TPI. Com a realização do presente trabalho, concluiu-se que os níveis de PT no poldro podem ser falíveis para a avaliação da TPI.
ABSTRACT - In the equine species the placenta is epitheliochorial, which does not allow the transfer of antibodies to the fetus during the pregnancy. Therefore, the transfer of immunity from the mare to the foal entirely depends on the ingestion and intestinal absorption of maternal immunoglobulins (Ig) from the colostrum in the first 24 hours of life. The neonatal infections are mainly due to the failure of passive transfer of immunity (FTPI) that has as main causes premature lactation, production of low quality colostrum or in reduced quantity and incapacity to suckle or failure to absorb the Ig. The main aim of this work consisted of the evaluation of factors that influence the transfer of passive immunity (TPI) through the determination of IgG and Total Protein in mares’ serum, their respective foals’ serum and colostrum (pre and post suckling). The determination of the colostrum density by a colostrometer, total protein content with the Bradford Protein Assay and the content of IgG by High Performance Liquid Chromatography were performed. Evaluation of the vital parameters of the foal in the post-partum period was carried out, as well as the determination of their risk category and it has been observed a relationship between the risk category and the IgG level in the foals’ serum. In the colostrum samples collected after suckling and considering the time elapsed since parturition, it was observed a significant decrease of the IgG:PT ratio. A correlation between mare’s serum IgG and colostrum could not be reached, as well as between the colostrum and the foals after suckling. However, mare’s serum IgG seem to positively influence the foals’ serum IgG level in the foals that had suckled. It could be observed an increased serum IgG levels in foals that had suckled comparing with the ones that did not, fact that confirms the important role of colostrum in TPI. With the completion of this work, a conclusion was reached that total protein levels in the foal can be considered an unreliable parameter to evaluate the TPI.

Full textThe aim of this study was to compare the use of two commercial extenders using chicken egg yolk with the same extenders, to which ema (Rhea americana) egg yolk was added. Six Criollo breed stallions were used during the off-breeding season period. Six collections per stallion were used. The ejaculate aspect, total and progressive motility were evaluated with a microscope; concentration was determined with a Neubauer counting chamber. After evaluation, semen samples were divided in two aliquots and diluted 1:1 in each of the centrifugation extender Equimix (Nutricell Nutrientes Celulares). For freeze that semen we used two commercial extenders: A (extender with glycerol) or B (extender with methylformamide) and was added 20% rhea egg yolk or 20% chicken egg yolk . Semen samples were examined at least 1 week after freezing, for total and progressive motility, physical and functional membrane integrity (HOST test and CFDA-PI fluorescence) (Lagares et al. 1998; Harrison & Vickers, 1990). The extenders of a given brand with or without rhea egg yolk had no significant difference according to total and progressive motility, although there was difference (p = 0,05) between extenders when different brands were compared, no matter if they were added Rhea egg yolk or not. Membrane functionality showed difference only when compared Extender A and B with Rhea egg yolk. Membrane integrity had no significant difference between all the treatments. These results show that Rhea egg yolk might be an alternative to making an equine semen extender.

Full textIn this study, three concentrations of N-acetyl- l-cysteine (NAC) were evaluated by sperm motility, membrane functionality (hypo-osmotic test), and sperm chromatin integrity. the hypo-osmotic test showed only 32.4% (P <0.05) of the cells having a functional membrane 12h into the cooling process, while the fresh semen (0h) was 53.5%. The percentage of motile cells decreased within 12h of cooling from 38.9 to 19.7%, with no difference between 12 and 24h of cooling. The tests of sperm chromatin dispersion and hypo-osmotic shock revealed similarities between the periods of cooling at 24 to 48h. In Experiment 2, the nine stallion ejaculates were divided into 4 equal parts, diluted in half with Kenney milk powder supplemented with 5.0, 2.5 and 0.5mM NAC and a group not supplemented (0.0mM). The evaluations were made fresh (0h), 24 and 48h after cooling. The analysis of motility was assessed in all experiments up to 24 hours. In experiment 2, the addition of 0.5 to 5.0mM NAC resulted in areas of similar sperm chromatin dispersion (59.7 and 55.5μM2, respectively). However, the area of the chromatin dispersion between non-supplemented group=0.0mM (65.3μM2) and 2.5mM NAC (52.8μM2) differ (P <0.05). The percentage of cells with plasma membrane function were similar between the supplemented with 0.5mM NAC and non-supplemented (0.0mM) groups with (39.7 and 39.8%, respectively), but higher than 2.5mM (34.5%) and 5.0mM (34.2%). Progressive motility of ejaculates supplemented with NAC were similar, but only the group with 0.5mM NAC which resulted in 35.2% of mobile cells showed similarities with the non-supplemented group (36.2%). The greatest damage to sperm chromatin in equine semen diluted with 50% seminal plasma kept cooled to 5°C was due to 24h cooling. The addition of 2.5 and 5.0mM NAC inhibits the mobility and functionality of the equine sperm membrane, but does not cause a deleterious effect on the integrity of the DNA.

Full textEquine piroplasmosis is caused by Theileria equi and Babesia caballi, which are important tick-borne hemoprotozoan, and cause impact to the equine industry worldwide. The disease can occur as an acute, subacute or chronic forms. Subclinical infection is common in endemic areas and animals that recover from primary infection usually become carriers and act as disseminate the disease. Due to the importance of horses in the maintenance of equine piroplasmosis, as well as the risk of introduction of these organisms into diseases-free areas, the aim of the present study was to detect antibodies against T. equi and B. caballi in a horse population highly exposed to tick bites in north and south-central region of Paraná State, southern Brazil. Thus, serum samples from 198 horse from different breeds, ages, and gender were analyzed by using a commercial competitive ELISA (cELISA) kit. In the north region, blood samples were collected from 32 horses from a rural settlement and 24 carthorses from Londrina city. In the south-central region, 142 blood samples from cart horses from: Colombo (n=48), Pinhais (n=76), and Curitiba city (n=18) were collected. A total of 193/198 (97.5%) horses were seropositive for at least one piroplasm. Antibodies anti- T. equi were found in 155/198 horses (78.3%), 137/198 (69.2%) were seropositives for B. caballi and 99/198 (50%) for both pathogens. Horses living in Colombo and Londrina were more likely to be seropositive for T. equi than those living in Curitiba (p < 0.05). In addition, horses >10 years and 5-10 years were more likely to be seropositive for T. equi than those <5 years (p < 0.05). No significant association was found between gender or presence of ticks, and seropositivity to T. equi (p > 0.05). In conclusion, the high seroprevalence of B. caballi and T. equi found reinforce the importance of active surveillance programs in endemic areas, since these horses may act as carriers of these piroplasms.

Full textGlycerin in food can be considered a good source of energy. Thus, its use as a substitute part of grains and other starchy foods is widely studied since these foods can cause metabolic and digestive changes when in high consumption. The objective of this study was to compare levels of glycerin addition in the equine diet. Eight male, castrated Mini-Horse male ponies, aged approximately 9 years ± 6 months, mean body weight of 149.80 ± 17.20 kg and mean body score of 5.4 ± 0.7 were used. The animals were housed in individual stalls. Individual daily consumption of 1.75% of body weight (CP) was used, with 1% CP in dry matter (DM) from bulky and 0.75% CP in DM from concentrate, with a ratio of 60:40 voluminous: concentrate). The experimental design used was the contemporary 4 x 4 double Latin square. The diets differed in the glycerin inclusion levels (0, 4, 8 and 12%) that were calculated in relation to the percentage of concentrate supplied per animal. The evaluations were performed in four periods, 14 days of adaptation to the diet, 5 days of total collection of feces (TCF) and 2 weeks of interval between periods. The total apparent digestibility of nutrients and fermentability of glycerol from the TCF were evaluated through glycemic, insulinemic, short chain fatty acid, non-esterified fatty acid (NEFA) and faecal pH analyzes. Safety and acceptability analyzes were also performed, which consisted of analyzes of liver and renal function, triglycerides, cholesterol and fractions, besides the evaluation of the animals\' feeding behavior. In addition to analysis of economic implications from the simulation of substitution of corn by crude glycerin. The data were submitted to analysis by the Statistical Analysis System (SAS Institute Inc., 2010). For the significant results, the Tukey test was used with P <0.05. There were no differences between treatments in any of the analyzes performed (P <0.05). Glycerin was palatable and acceptable. The substitution of corn for glycerin, even at 1%, represents economically 0.42% gain. The supplementation of crude glycerin in the equine diet presents itself as safe, without affecting the alimentary behavior, the hygiene and the digestive health of the animals, with economic justification for use.
