In dairy farming, cows display important metabolic changes during the transition period, particularly high-production cows, which need nutrients in greater quantity to meet the required demand. The aim of this study was to determine the prevalence of subclinical hypomagnesemia in pre- and post-partum dairy cows inserted in milk-production systems in the Sousa microregion and the district of São João do Rio do Peixe, both in the State of Paraíba, Brazil. As such, visits were made every two weeks to 34 rural properties, where the team collected 357 blood samples by venepuncture, 106 from pre-partum lactating cows and 251 from lactating cows in the post-partum period. It was found that the properties supplied three types of mineral supplement: a single supplement of NaCl, a supplement of NaCl + mineral base, and a commercial supplement. The cows receiving the commercial mineral supplement had the highest prevalence (10.53%) of the disorder, even showing a significant difference (P < .05) between the other types of supplement. In relation to reproductive period, it was found that the post-partum cows had a higher prevalence of subclinical hypomagnesemia (9.96%) than did the pre-partem cows (8.49%); there was, however, no significant difference (P > .05) between the two. Studies such as this are fundamental for alerting rural and technical producers to the occurrence of subclinical hypomagnesemia in the region, in addition to the damage caused by metabolic disorders.
<p class="Default">Technological innovation has had a remarkable rise and its use in rural areas has become a subdisidiary method for both producers and professionals in the agrarian area. In dairy cattle, there is a lack of information about nutritional management. The supply of minerals is inadequate and it does not meet the requirements of animals often. The objective of this study was to develop an application to estimate the nutritional requirements of calcium for dairy cows and to help producers to provide adequate amounts of this mineral. The application was created from the Java platform, using recommendations from the National Research Council (NRC), with calculation of requirements for maintenance of lactating and non-lactating cows, females in growth, gestation. The application enables the filling of data from animal characterization to the type and quantity of concentrate and forage provided. After filling the data the application will generate the result informing whether the cow in lactation has a deficit, surplus or if it is receiving adequate amounts of the mineral. It also demonstrates the amount of calcium that should be increased or decreased, according to the needs of each animal. Using the bovine calcium application, producers will provide an appropriate supplement, reducing unnecessary costs and increasing milk production.</p>
Prejuízos decorrentes de manejo nutricional inadequado, principalmente no que se refere à suplementação mineral, confere problema corriqueiro enfrentado por muitos produtores de vacas leiteiras, levando a diminuição na produção e consequentes perdas econômicas. Desta forma, objetivou-se com a iniciativa de extensão a realização de campanhas para conscientização do manejo adequado de suplementação mineral em bovinos leiteiros de produtores inseridos nos municípios de Sousa, São João do Rio do Peixe, Santa Helena e Paulista, localizados no Sertão Paraibano. O público efetor foram discentes do curso de Bacharelado em Medicina Veterinária do Instituto Federal de Educação, Ciência e Tecnologia da Paraíba. Utilizou-se a metodologia participativa com o princípio de troca de saberes e reorganização de conceitos. Os recursos utilizados para ministração das palestras nas campanhas foram data show, banners, cartazes e vídeos. Durante visitas às propriedades foi possível verificar que o manejo não era realizado de forma adequada, identificando erros como fornecimento limitado de suplementação mineral, mistura e diluição de sal comercial com sal comum e cochos de tamanho inadequado. Porém após intervenção da equipe, os produtores conseguiram modificar essa realidade e afirmaram conseguir melhorias na produção e sanidade dos animais com adoção das práticas de manejo aprendidas durante as campanhas e dias de campo.
<p>A alta demanda energética enfrentada por vacas leiteiras durante o período de transição, associada ao balanço energético negativo, podem levar à mobilização excessiva de lipídeos, acarretando em danos ao fígado. Objetivou-se avaliar o perfil sérico de fosfatase alcalina de vacas leiteiras durante o pré e pós-parto na microrregião de Sousa-PB. Foram coletadas 284 amostras sanguíneas, sendo 106 de vacas no pré-parto e 178 de vacas do pós-parto e realizada mensuração da enzima. Nenhuma das amostras avaliadas apresentou valores séricos da enzima acima do normal, indicando que os animais não apresentavam lesões hepáticas. A avaliação da fosfatase alcalina auxilia na prevenção de distúrbios durante o período de transição, porém para confirmação do diagnóstico deve-se levar em consideração avaliação de outros metabólitos e sinais clínicos.</p>
Problems related to the locomotor and gastrointestinal systems correspond to the highest percentage of clinical cases. However, diseases related to the respiratory system can result in low animal performance or even the animal’s removal from athletic life. This paper aims to report a case of permanent tracheotomy in a horse. The animal was treated at the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital - HOVET, with respiratory noise and dyspnea claims. In the anamnesis, the owner reported that the animal had been presenting respiratory difficulty for 20 days. On physical examination, respiratory noise and dyspnea were noted. Endoscopy was performed, from which a marked decrease in the arytenoid cartilage movement on the right and left sides was noted. It was possible to diagnose a stage IV case of bilateral laryngeal hemiplegia, combining clinical signs with endoscopy findings. Thus, the surgical treatment of permanent tracheostomy was chosen. After surgery, drug therapy using antibiotics and anti-inflammatory drugs was performed. In addition, a nº 6 metal tracheostomy cannula was inserted. After 36 days of hospitalization, the animal was discharged with regression of clinical signs.
