ABSTRACT
Treatments of postsurgical dehorning in cattle usually includes topical application of healing agents in wounds. The Bacterial Nanocellulose (BNC) may come to a complementary treatment for these wounds. Two new complementary treatments with BNC and BNC loaded with nisin were evaluated for wound healing in surgical dehorning in bovine. Hence, two groups of experiments were run, and 12 animals were used in each group. All animals, in right and left horns, received antisepsis treatment. For the first group, the left horn was the control, and on the right one the BNC was applied. For the second group, BNC was applied on the left horn (control) and on the right ones BNC+nisin was applied. In both experiments, wounds were evaluated macroscopically by photographic images and microscopically by histology. For macroscopic evaluations, a significant difference was observed over time, but only in the comparison within the same groups. Microscopic analyzes did not showed significant differences in any type of comparison. In conclusion, there was a clinical improvement in the wound healing response with the application of BNC. However, there was no significant difference between BNC compared to the nisin loaded in BNC. For the first time it was applied a BNC in surgical dehorning wounds in bovines and evaluated the efficacy of treatment in a real animal handling situation.
ABSTRACT
The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling of newborn male calves; and dehorning without pain mitigation. To address the first aim 40 participants were interviewed using open-ended semi-structured questions designed to probe their views and attitudes about dairy production in Brazil, and 300 participants answered a questionnaire that included an open-ended question about the welfare of dairy cattle. Primary concerns reported by the participants centered on milk quality, which included the rejection of any chemical additives, but also animal welfare, environmental and social issues. The interviewees rarely mentioned animal welfare directly but, when probed, expressed several concerns related to this topic. In particular, participants commented on factors that they perceived to influence milk quality, such as good animal health, feeding, clean facilities, and the need to avoid or reduce the use of drugs, hormones and pesticides, the avoidance of pain, frustration and suffering, and the ability of the animals to perform natural behaviors. To address our second aim, participants were asked questions about the four routine management practices. Although they self-reported being largely unaware of these practices, the majority of the participants rejected these practices outright. These data provide insight that animal welfare may be an important issue for members of the public. Failure to consider this information may increase the risk that certain dairy production practices may not be socially sustainable once lay citizens become aware of them.
ABSTRACT
A actinobacilose bovina ou "língua de pau" é uma enfermidade esporádica que resulta na glossite granulomatosa dos animais acometidos. A enfermidade comumente é secundária a traumas da cavidade oral pela ingestão de alimentos grosseiros, embora também há relatos de actinobacilose atípica após a realização de procedimentos cirúrgicos. Relata-se a doença em uma novilha da raça girolanda, 15 meses de idade, apresentando sialorréia, protrusão e edema da língua após 20 dias de submetida ao procedimento de descorna cosmética. O diagnóstico foi baseado no histórico clínico e nos achados de cultura bacteriana com isolamento de Actinobacillus lignieresii. O animal foi submetido ao tratamento com antimicrobiano de amplo espectro, além de lavagem bucal com solução antisséptica até completa resolução do quadro clínico.
The bovine actinobacillosis or "wooden tongue" is a sporadic disease that results in granulomatous glossitis of affected animals. The disease is commonly secondary to trauma of the oral cavity by the ingestion of stemmy forage. However there are also reports of atypical actinobacillosis after surgical procedures. It is reported a heifer of Girolanda breed, 15 months old, presenting drooling, tongue protrusion, tongue edema after undergoing the dehorning procedure. The diagnosis was based on clinical history and on bacterial culture for Actinobacillus lignieresii. The animal was subjected to therapy with broad-spectrum antibiotic plus mouthwash with antiseptic solution until complete resolution of the clinical status.
Actinobacilosis bovina o "lengua de madera" es una enfermedad esporádica que se traduce en glositis granulomatosa de los animales afectados. La enfermedad es comúnmente secundaria a trauma de la cavidad oral por la ingestión de forraje, sin embargo también hay informes de atípica actinobacilosis después de procedimientos quirúrgicos. Se informa de una novilla de raza girolanda, 15 meses de edad, con sialorrea, protuberancia y edema de lengua, edema después de 20 días de haber sido sometido al procedimiento de descuerne cosmética. El diagnóstico se basa en la historia clínica y los hallazgos en el cultivo bacteriano como Actinobacillus lignieresii. El animal se sometió a terapia con antibióticos de amplio espectro más enjuague bucal con solución antiséptica hasta la resolución completa del cuadro clínico.

A descorna cirúrgica em bovinos adultos pode resultar em uma série de complicações trans e pós-operatórias. A deiscência é mais comum, principalmente por tensão exagerada na linha de sutura quando não há pele suficiente para aproximação das bordas. O objetivo deste trabalho foi comparar duas técnicas de descorna cirúrgica e propor um método alternativo para redução de tensão na linha de sutura. Foram utilizados 20 bovinos mestiços (Bos taurus/Bos indicus), sendo que em dez, foi utilizada a técnica de descorna rotineira no corno direito e no esquerdo a técnica proposta. Nos demais, foi realizada, no corno direito a técnica proposta e no esquerdo a técnica rotineira. A técnica rotineira constou de ressecção de uma elipse de pele sobre a base do corno, divulsão tecidual, amputação do corno com fio serra e dermorrafia com fio poliamida 0,80 em padrão de sutura interrompida simples. A técnica cirúrgica proposta consistiu de uma incisão retilínea iniciada próximo à eminência nucal até a base medial do corno, completada com uma incisão curva formando uma meia elipse em direção latero-rostral. Na base lateral do corno foi excisada outra meia elipse posicionada latero-caudalmente. Após a amputação do corno com fio serra, realizou-se a dermorrafia como na técnica rotineira. A técnica proposta reduziu o tempo de cirurgia, possibilitando menor divulsão tecidual, com adequada aproximação das bordas da ferida e menor tensão na linha da sutura.

Metal clamps were used in dermal suture of fifty crossbred cattle, of various weight, ranging from 1.5 to 5 years of age; after esthetic dehorning. The animals were operated on differents farms from Goiás State, Brazil, during 1995 and 1996 and evaluated after surgery. Four animals showed serous exudation two days after surgery. One animal had unilateral sinusitis and in other three there were wound dehiscence. The technique proposed was fast; skin divulsion was easier, there was a good hemostasy and cicatrization was esthetic. Metal suture is fast and easily applied.
Os grampos de metal foram empregados na dermorrafia de 50 vacas mestiças (Zebu/Holandês) de peso variado, com idade entre 18 e 60 meses após serem submetidas à descorna plástica. Os animais foram operados em diferentes propriedades rurais do Estado de Goiás, durante os anos de 1995 e 1996 e avaliados durante o pós-operatório. Quatro animais apresentaram exsudação serosa local, dois dias após a cirurgia; um animal desenvolveu sinusite unilateral e, em dois outros, houve deiscência da ferida. A técnica utilizada reduziu o tempo de cirurgia, facilitou a divulsão da pele e produziu hemostasia satisfatória. A aplicação dos grampos foi rápida e fácil, e a cicatrização satisfatória.
