Abordagem clinica e estratégias de manejo da cinomose em canídeos silvestres: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) FARIA, Alex Takahashi de; CARVALHO, Ana Luisa Gonçalves de; TORRES, Maria Lúcia Marcucci
The study on distemper reveals that this viral disease can affect several native species, resulting in serious consequences for populations of wild canines, whether kept in captivity or not, with high rates of morbidity and mortality. The clinical signs observed in wild canines are similar to those found in domestic dogs and include lethargy, fever, nasal and ocular secretion, in addition to severe neuromuscular complications that can develop over time. The transmission of the virus between different species represents a significant threat to the conservation of wild species, especially due to the proximity of urban areas to the natural environment, which results in the fragmentation and degradation of habitats. In addition, the migration of domestic species to conservation and rehabilitation centers also contributes to the spread of the virus, since animals can carry pathogens and transmit the disease to wild species. This work highlights the importance of an effective clinical approach in the management of distemper for the conservation of wild canines, demonstrating the importance of adopting appropriate diagnostic methods and treatment strategies, as well as the application of preventive measures for the intervention and spread of the disease between species, thus protecting the health of these animals and preserving them from infectious diseases.
Acupuntura na Medicina Veterinária em pequenos animais: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) BENASSI, Lívia Araújo; PAIVA, Jhenifer Antonucci; GONÇALVES, Brenna Maria Cyrino Nogueira
Acupuncture is a Traditional Chinese Medicine therapy that uses specific points throughout the body, called acupoints, to insert needles and/or transfer heat to defined areas of the skin. This, through nerve stimulation, triggers responses in other areas of the body with a cascade of local, regional or systemic physiological effects, with the purpose of correcting possible energy imbalances responsible for causing diseases and/or pain. In veterinary medicine, there are 32 simple points and 40 bilateral points that are most commonly used in small animals. The points can be stimulated through various techniques in addition to traditional acupuncture, such as moxibustion, acuinjection, electroacupuncture, among others. The most commonly used techniques are used to control pain, and may also have significant effects in the treatment or adjuvant therapy in animals with neurological dysfunctions and/or sequelae, musculoskeletal dysfunctions or even behavioral disorders such as anxiety, aggression and fear in small animals. Acupuncture has been shown to be a safe, effective therapy with no side effects. Therefore, this study performs a literature review with the aim of elucidating the techniques and uses of acupuncture in small animals within veterinary medicine, emphasizing numerous benefits as an adjuvant treatment in various pathologies within the clinical routine.
Análise macroscópica comparativa do intestino do Puma Concolor e Felis Catus
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) MARQUES, Mariana Nogueira; RIBEIRO, Camila; MANÇANARES, Celina Almeida Furlanetto; AIUB, Plinio Bruno; VITOR, Victório Jordão; ROSA, Ricardo Alexandre
This study compared the macroscopic anatomy of the intestine of domestic cats and the Puma concolor, which is one of the largest felines in Brazil, widely distributed throughout the country, and is highly relevant as a flagship animal that suffers enormous losses due to human action. Due to its extreme national importance, the study of its anatomy is essential for academic, clinical, surgical purposes and for actions to preserve it. Since the digestive system is one of the main agents for the homeostasis of an organism, anatomical knowledge of the intestine, the largest portion of this system, is essential. The intestine of felines is divided into the small intestine, composed of the duodenum, jejunum and ileum, and the large intestine, composed of the cecum, colon and rectum. This work aims to analyze, describe and catalog the morphology of the intestine of the puma (Puma concolor) to improve anatomical knowledge of this animal for a variety of needs, such as scientific work, clinical and surgical assistance, environmental and food management, and mainly to help preserve and conserve this species.
Análise microscópica comparativa do intestino da Puma Concolor e Felis Catus
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) RIBEIRO, Camila; MARQUES, Mariana Nogueira; MANÇANARES, Celina Almeida Furlanetto; AIUB, Plinio Bruno; VITOR, Victório Jordão; ROSA, Ricardo Alexandre
This study compared the microscopic anatomy of the intestine of Puma concolor with that of the domestic cat in order to describe, evaluate and catalog the differences and similarities in the intestinal morphology of these species. The intestine is the largest portion of the digestive system and is extremely important for the proper functioning of the organism. Under microscopy, both intestines have mucosal, submucosal, muscular and serous layers; however, only the small intestine has villi, while this structure is absent in the large intestine. The microscopic intestinal anatomy of domestic and wild felines is similar. The puma is one of the largest felines in Brazil, widely distributed throughout the national territory, and is highly relevant in the country. Furthermore, it is a national animal and suffers enormous losses due to human actions. Therefore, this research aims to enrich the anatomical knowledge of Puma concolor to assist in clinical and surgical care, environmental management, and mainly in the preservation of this species.
Anestesia em lagomorfos para procedimentos odontológicos: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) CUSTÓDIO, Marina Mendonça; BONFANTE, Juliana da Silva
The wild animal clinic has been growing significantly in recent times, especially the lagomorph clinic, which, due to their high docility and easy adaptation to their owners, has aroused people's interest in acquiring them as pets. Despite their gentle temperament, rabbits are animals that become stressed easily, requiring greater care on the part of the veterinarian when handling and restraining these animals. Consequently, it is necessary to know the physiological, anatomical and pharmacological particularities of the species, considering that rabbits have a high chance of developing dental problems, often requiring surgical treatment. Therefore, it is essential to choose an anesthetic protocol appropriate for the animal in question, having knowledge about the drugs to be used, their possible side effects and establishing the important points that must be followed during the anesthesia. Furthermore, during the entire surgery it is necessary to monitor the patient's vital parameters, always aiming to provide greater safety to the procedure and greater comfort to the animal. The present work aims to report on the different drugs that can be used in routine anesthetic procedures in lagomorphs, highlighting the manner of use and their effects, as well as the particularities of the species in question.
Avaliação do exame coproparasitológico na gestão sanitária de fazendas produtoras de gado de corte: relato de caso
(Centro Universitário da Fundação de Ensino Octávio Octávio Bastos, 2024-10-09) FERRI, Luis Daniel de Castro; SILVA, Vitor Montouro da; VARZIM, Fernanda Leme da Silva Bastos
Cattle slaughterhouses are considered one of the most important places for diagnosing diseases transmitted by animals. These diseases can be inflammatory, infectious, zoonotic and, in most cases, parasitic. Diseases of parasitic origin are rarely detected during ante mortem examinations because the animals often do not present major clinical signs to be observed at the time of inspection. Major economic losses often occur due to the disposal of organs and carcasses when affected by parasitic diseases. Therefore, the correct detection, sanitary control and treatment of parasitism on the farm itself is of great importance and value. To this end, the objective of this production was to evaluate fecal samples through coproparasitological examination of beef cattle confined on a farm, correlating them with the sanitary protocol used for these animals and the final certificate from the cattle slaughterhouse. After the positive results in these animals, and information, he made other rural producers, under the guidance of the veterinarian, use the same health protocol in a personalized way in their animals, in order to evaluate and prove its effectiveness, as well as reduce their economic losses, ensuring greater profitability when slaughtering their animals.
Babesiose canina: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) HONÓRIO, Vinícius Martinelli; CUSTÒDIO, Marina Mendonça; TONON, Mariely Thais de Souza
Canine babesiosis is a disease caused by a protozoan transmitted mainly through Rhipicephalus sanguineus and blood transfusions contaminated by the agent Babesia sp., capable of infecting the cells of the hematopoietic system (red blood cells). It is a disease that commonly causes hemolytic anemia in dogs. Affected animals often present apathy, weight loss, fever, diarrhea, anorexia, and lymphadenopathy, and may present in subclinical, hyperacute, acute, or chronic forms, negatively affecting the health of the animals. To diagnose the disease, the use of serological methods, blood smears, and molecular methods (PCR) are alternatives, each of which has its own particularities for each phase of the disease. Once diagnosed, the animal must undergo supportive treatment associated with the use of drugs that combat the protozoan, thus ensuring a more effective recovery. Diagnosing and treating the disease early makes the prognosis more favorable, thus avoiding the chances of complications from the disease. Controlling the vector both in the animal and in the environment in which it lives is essential to minimize the risk of contagion of the disease, preventing the spread of the agent. The objective of this review is to report on the involvement of dogs by babesiosis, covering the epidemiology, clinical changes, diagnosis, treatment, prognosis and prevention.
Cinomose em lobo guará Chrysocyon Brachyurus no Brasil
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) JOANA, Luana Passos; AIUB, Plinio Bruno
Canine distemper is a highly contagious multisystem disease transmitted by the canine distemper virus, which belongs to the Paramyxoviridae family and the Morbillivirus genus. Its main clinical signs consist of purulent oculonasal secretion resulting from pneumonia due to secondary infection, fever, cough, anorexia, vomiting, dermatitis and depression. Neurological signs such as seizures, muscle rigidity, spasms, paresis, paralysis, ataxia, motor incoordination, blindness and myoclonus also occur in more advanced stages of the disease. The domestic dog is its main reservoir, however, it can also affect several species, such as the maned wolf, a wild canid. Infection of wild animals by the disease, resulting from urban encroachment into protected areas and an increase in the number of unvaccinated stray domestic dogs, poses a threat to wildlife conservation. Treatment of the disease consists of alleviating symptoms, either with supportive therapy, antipyretics, anticonvulsants and even antibiotics to prevent secondary infections. Since there is no specific treatment for this disease, the main way to combat it is through prevention. Studies have shown that the modified live virus vaccine used in domestic dogs is safe and effective for maned wolves, both in adulthood and as pups. However, this scenario becomes unlikely when it comes to free-living animals, making prevention extremely difficult.
Doença renal crônica em felinos domésticos: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) HONÓRIO, Vinícius Martinelli; LIMA, Júlia Cristini Ribeiro de; GONÇALVES, Brenna Maria Cyrino Nogueira
Chronic kidney disease (CKD) is a disease characterized by loss of functional quality and/or irreversible structural damage to the kidneys that commonly affects domestic felines, especially older ones, resulting in decreased kidney function over months to years. There are congenital and acquired causes that can trigger the disease, causing affected animals to frequently present clinical signs such as lethargy, vomiting, dehydration, polyuria, uremic ulcers and weight loss, generating a significant impact on the quality of life and longevity of these pets. To diagnose the disease, it is necessary to analyze the clinical signs presented by the animal together with the results of laboratory tests that evaluate kidney function, as well as the use of ultrasound, which is a crucial imaging test to evaluate kidney morphology and detect possible lesions. Since it is an irreversible disease, treatment becomes palliative, through means that slow the progression and aim to minimize the clinical impact of the disease on the patient. Staging the disease is essential for guiding treatment and patient prognosis. This classification takes into account serum creatinine levels and other markers of kidney damage, as well as the clinical signs presented by the animals. The objective of this review is to report on the involvement of felines by chronic kidney disease, including clinical and laboratory changes, diagnosis, treatment and prognosis.
Estafilectomia com rinoplastia em buldogue francês: Relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) MICHELETTI, Carolina Dantas; IZIDORO, Letícia Cristina; NOZAWA, Marcela Helena; GONÇALVES, Brenna Maria Cyrino Nogueira
Brachycephalic dog syndrome is prevalent in breeds such as Pugs, Boxers, Shih Tzus, French Bulldogs and English Bulldogs, due to anatomical abnormalities such as nostril stenosis and elongated soft palate. Consequently, these changes lead to several complications such as eversion of laryngeal sacs and tonsils, macroglossia and tracheal collapse, which generate significant consequences for the animals, mainly esophageal and gastric distension due to increased respiratory effort. Symptoms include noisy breathing, stridor, increased inspiratory effort, coughing, altered voice, episodes of emesis, cyanosis of the mucous membranes and syncope. Diagnosis is based on history, clinical signs, physical examination and complementary exams such as cervical and thoracic radiographs to evaluate tracheal narrowing. Finally, surgical treatment is essential, with staphylectomy to reduce the lengthening of the soft palate and rhinoplasty to remodel the nasal structure, in addition to palliative measures such as maintaining cool environments and controlling physical effort. Thus, this case report addresses the accurate diagnosis, surgical treatment and recovery of respiratory syndrome in a French Bulldog, highlighting the importance of early intervention and postoperative care to improve its quality of life.
Estudo retrospectivo de casuística das enfermidades de equídeos atendidos no setor de grandes animais do Centro Universitário UNIFEOB
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TODERO, Larissa Midiane; SILVA, Lara Romero; CELOTTI, Gustavo
Whether for work, leisure or sports, the number of equines has been growing worldwide, which proves and increases the interaction of these animals with humans, as well as their importance for people's way of life and well-being. Through a retrospective data collection, this study collected data from the medical records of equines treated in the large animal sector of the Veterinary Center of the Octávio Bastos Foundation for Education University (UNIFEOB) from March 2018 to March 2023. Through the medical records, 434 animals were analyzed, with emphasis on the following data: breed, species, sex, age, weight, outcome and diseases according to the affected system. According to the statistics obtained in this study, it can be concluded that the category that had the most animals treated was that of gastrointestinal diseases, with 147 animals treated, representing approximately 33.9% of the care that occurred from March 2018 to March 2023. Right after that were musculoskeletal care, with 77 occurrences, approximately 17.7% of the total. Therefore, the objective of this research was to identify the profile of the equines and the main diseases that affected these animals treated at the veterinary center during the period analyzed.
Falha na trasferência de imunidade passiva em neonato equino: Relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) SILVEIRA, Ana Claudia Cassiano; COELHO, Bruno Machioni; RIBEIRO, Amanda
Failure of passive transfer of immunity (FTIP) is a relatively common immune condition in equines, as the newborn needs maternal antibodies, originating from colostrum, to have immunological protection in the first weeks of life, which is called passive immunity. The antibodies present in colostrum are immunoglobulins and are transferred to the newborn only in the first hours of life through the ingestion of colostrum. This colostrum is formed approximately 30 days before parturition and is essential for the maintenance of the foals' lives, being able to maintain significant serum levels of immunoglobulins up to 90 days of life. In many cases, the newborn foal does not ingest colostrum or ingests a small volume, and this may be related to several factors, from difficulty in standing up, difficulty in suckling, pre-existing diseases from intrauterine life and even failure in the production of colostrum by the mare. Failure to ingest colostrum results in FTIP and can lead to dehydration, hypoglycemia and later to infections or even sepsis, in the first hours of life. In these cases, the foal may die if not treated quickly. Therefore, this study aims to report a case of FTIP in a newborn horse treated at the UNIFEOB Veterinary Center.
A fisiologia do ciclo estral da fêmea canina: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) CADETIO, Giovana Carneiro; CONCEIÇÃO, Juliana Costa Zuppi da
Female dogs are monoestrous domestic non-seasonal species that do not depend on the season to ovulate and, therefore, their ovulation is spontaneous. The estrous cycle of female dogs is not something concrete, as each female dog has its own cycle and specific behavior in each reproductive phase. Puberty varies between six and 10 months in small dogs and eight to 24 months in large dogs. The reproductive cycle of female dogs is divided into four distinct stages: i) proestrus (lasting five to 20 days); ii) estrus (lasting four to 12 days); iii) diestrus (lasting 60 days); and iv) anestrus (lasting 120 to 240 days). Ovulation occurs in the face of a high dose of luteinizing hormone (LH) and follicle stimulating hormone (FSH), and can last from 48 to 60 hours after the peaks of these hormones. Diagnosis of the phases of the estrous cycle is performed through complementary exams such as vaginal cytology, hormone level measurement (progesterone and estrogen), ultrasound and vaginoscopy. The behavior of the dog will depend on which phase of the reproductive cycle she is in, since each phase has a predisposing hormone that causes changes and modifications in her behavior and reproductive anatomy. In view of this, it is important to seek to improve more effective methods for diagnosing the different phases of the estrous cycle. This could include research and development of new diagnostic techniques that are more accurate, faster and accessible to veterinarians.
Haemonchus Contortus como causa de atrofia gelatinosa cardíaca em caprino: Relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TEIXEIRA, Luiza Ramos; OLIVEIRA, Braian Rombaldo de; MARTINELLI, Paulo Edson Baptista; ESTEVAM, Kamile Jorge; SANTOS, Gabriele Araújo Rodrigues dos; BIRGEL, Daniela Becker; BIRGEL JÚNIOR, Eduardo Harry
Haemoncosis is an important parasitic disease that normally affects sheep and goats and is caused by the nematode of the genus Haemonchus, of the Trichostrongyloidea family. Its evolutionary cycle has a period of development in the host, called the parasitic phase, and another called the environmental phase. This parasite is known for its extreme resistance to anthelmintics, becoming a major problem for goat and sheep farming. The control of haemoncosis depends on early awareness by the producer, monitoring the proliferation of H. contortus and management protocols and prophylactic measures such as anthelmintic treatments. The clinical signs observed are anemia, apathy, hypoproteinemia, anorexia, dehydration, weight loss, generalized edema and decreased milk production. Among the necropsy findings, gelatinous atrophy of cardiac fat can be seen, which is normally observed in cachectic animals, or those undergoing some process of carbohydrate deprivation, or any process that results in an abrupt loss of body weight, requiring the use of lipid reserves, initiating a process of lipolysis and mobilization of this fat for ATP synthesis. The present study aims to report a case of haemoncosis in a goat in which gelatinous cardiac atrophy was observed as one of the necropsy findings.
Hiperadrenocorticismo em felinos: manifestações clinicas, métodos diagnósticos e tratamento - Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) BIZAIA, Emily Cristina; RIBEIRO, Camila; GONÇALVES, Brenna Maria Cyrino Nogueira
Although uncommon in felines, hyperadrenocorticism is an important condition to understand in this species, since it presents a challenging diagnosis and treatment. The most common clinical signs are polyuria, polydipsia, polyphagia, skin atrophy, bulging abdomen, symmetrical bilateral alopecia, weight gain and muscle atrophy. These are usually the same symptoms as diabetes mellitus or skin hyperfragility, since hyperadrenocorticism can be related to these pathologies. In laboratory tests, stress leukogram, hyperglycemia, glycosuria and hypercholesterolemia are common, and there may also be an increase in ALT and ALP. In addition to laboratory tests, this disease requires a more specific diagnosis, such as low-dose dexamethasone suppression tests, adrenocorticotropic hormone stimulation or high-dose dexamethasone suppression tests, and also the cortisol-creatinine ratio. For treatment, the use of trilostane, cabergoline, radiotherapy or hypophysectomy for pituitary tumors and unilateral or bilateral adrenalectomy are indicated. The objective of this work is to carry out, through bibliographic research, a review of the pathology of hyperadrenocorticism in felines, so that we have a deeper understanding of it, since it is less common, and thus obtain knowledge about the diagnosis and more effective forms of treatment.
Hiperplasia endometrial cística em cadelas: Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) CADETIO, Giovana Carneiro; SANTOS, Débora Nogueira dos; CONCEIÇÂO, Juliana Costa Zuppi da
Cystic endometrial hyperplasia, or more popularly known as pyometra, is one of the main reproductive disorders found in routine veterinary clinics, and is therefore the most common in female dogs. Pyometra refers to an inflammatory process in the uterus, which is caused by a hormonal influence associated with a bacterial infection with accumulation of purulent secretion. Symptoms range from mild, such as anorexia, apathy, to more severe signs, such as emesis, diarrhea, polyuria, and polydipsia due to lesions in the renal parenchyma by previously formed immune complexes. The patient may possibly die. Pyometra can manifest itself in two forms: open (open cervix) or closed (closed cervix), with the closed form being the most dangerous. Diagnosis is made through clinical signs, patient history, and additional tests, such as laboratory tests, ultrasounds, and radiographs. Treatment should be emergency due to the risk of progression to sepsis. In view of this, the most indicated treatment is surgical procedure, ovariohysterectomy, however, in some cases clinical treatment with the use of medication may be chosen, especially in breeding females. The prognosis depends on the clinical case and the patient's recovery, but is considered poor to poor. In view of this, it is important to analyze the different methods of diagnosis, treatment and prognosis of pyometra in female dogs, aiming to provide relevant information for an effective and improved approach to this clinical condition in veterinary settings.
Malformações congênitas em bezerros decorrentes do consumo do bagaço de maçã na alimentação de vacas prenhes na região sul do país: Revisão de literatura
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) OLIVEIRA, Braian Rombaldo de; PEREIRA, Aline Aquino; CONCEIÇÂO, Juliana Costa Zuppi da
Apple pomace is widely used in cattle feed in most of the southern region of Brazil, and is composed of peels, stalks, leaves, seeds and pulp, with components such as fiber, sugars, low levels of lipids, proteins, vitamins and minerals. This product has been linked to congenital malformations in calves, resulting from the ingestion of pomace by the pregnant mother, although there is no evidence that this relationship actually exists. However, after several studies, it was found that it is not the apple pomace itself that causes the malformation, but rather the components present in this pomace, which may be pesticides used in apple production and cultivation that can cause mutagenicity, as well as mycotoxins that also cause mutagenicity. Another possible cause is manganese deficiency, due to excessive ingestion of apples, which have low levels of manganese in their pulp. The malformations caused by this are chondrodysplasia and dwarfism, and these diseases are recognized as diseases that hinder the growth and development of the animal, due to the conditions in which the animal is born, such as short, curved, rigid bones, and coarse joints. It is also possible to find malformations in organs, thus preventing their proper functioning. Thus, the objective of this work is to compile data from the literature, addressing the main causes of congenital malformations in calves from pregnant cows fed apple pomace in the southern region of the country.
Maximizando a produção de milho com UTRISHA N®: um avanço sustentável na alimentação animal - Revisão bibliográfica
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) SANTOS, Bruna Pan dos; COSTA, Leonardo; VERDURICO, Lenita Camargo
Currently, the cereal with the largest production in the world is corn, and in Brazil, 46% of its total production is destined for animal feed. In animal nutrition, corn is used to feed both ruminants and non-ruminants and, despite not having much protein, it is an excellent source of energy. Therefore, to ensure that corn crops achieve good productivity, it is important to provide macronutrients such as nitrogen, potassium, phosphorus, calcium and magnesium in adequate quantities, as they are required in greater quantities by plants. Thus, aiming at sustainable advancement in animal nutrition together with maximizing corn production, this review examines the use of Corteva Agriscience's commercial biological inoculant Utrisha N®, developed with the exclusive strain of Methylobacterium symbioticum, a Gram-negative, strictly aerobic, rod-shaped bacterium, which aims to reduce the application of nitrogen fertilizers, promoting sustainable agriculture, since, in addition to fixing atmospheric nitrogen, the product stimulates plant growth, reducing the need for fertilizers by up to 50% in certain crops. Measures like this not only promote agricultural efficiency, but also minimize environmental impact, highlighting the importance of sustainable agricultural practices in the production of animal feed.
Megaesôfago secundário a persistência do quarto arco aórtico direito em felino: Relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TAGLIAFERRO, Karoline Saturnino; AZEVEDO, Giovana Helena da Silva; TORRES, Maria Lúcia Marcucci
Persistence of the fourth right aortic arch is characterized by being a congenital vascular ring anomaly most commonly observed in dogs, considered rare in cats, comprising 95% of all vascular ring anomalies found in small animals. This condition results from malformations arising from changes in the embryogenesis of the aortic arches, where the right aortic arch persists in relation to the left aortic arch, leading to esophageal stenosis and, consequently, megaesophagus. The most evident clinical signs are regurgitation, weight loss, excessive appetite, apathy and discomfort after meals, in addition to dehydration and weakness, especially in puppies, in which dry food has recently been introduced. Respiratory signs may be associated with secondary aspiration pneumonia, due to megaesophagus. The diagnosis can be obtained through the analysis of clinical signs together with imaging tests, such as computed tomography, magnetic resonance imaging and simple or contrast radiography of the cervicothoracic region, where esophageal dilatation is visualized mainly with the contrast medium. Treatment is performed through a surgical procedure together with adjustment of dietary management, with a reserved prognosis, according to the clinical picture of each individual. Thus, the present study aims to describe the case report of persistent fourth aortic arch with secondary megaesophagus in a feline, in which the surgical procedure was performed as a treatment method.
Nutrição na bovinocultura de leite: Revisão de literatura
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) RODRIGUES, Rafaela F.; BUSSOLO, Rafaela M.; V. JÚNIOR, Paulo Cesar
This paper addresses the crucial influence of adequate nutrition on the production and health of dairy cattle. The research explores how a balanced diet that meets the specific nutritional requirements of dairy cows can significantly increase production and improve the quality of milk produced. In addition, the impacts of inadequate nutrition, such as nutritional deficiencies and health problems, which can negatively affect both milk production and quality, are discussed. During the dry, pre-calving, lactation and post-peak periods, animals will have varying nutritional requirements. These changes are influenced by feed intake capacity, body weight and the amount of milk produced. Cows that produce large volumes of milk require a substantial amount of nutrients for milk production and often have to draw on their body reserves, especially in the first few days after calving. During this critical period, the demand for nutrients is high to sustain milk production, which may result in the cow using body reserves to meet these increased metabolic needs. It is concluded that the basis for quality milk production is adequate food and nutritional management, meeting all needs and thus achieving optimal production and animal well-being.
