RESUMO

Pathological changes in the umbilical region are common in calves. Among such alterations, omphalitis is included. This term is used to define inflammation and infection of the external structures of the umbilicus. According to the affected structures, it can be subclassified into omphalophlebitis, omphaloarteritis, omphalourachitis and panvasculitis. These inflammations are usually associated with bacterial infections. There are predisposing conditions that include inadequate handling such as poor hygiene and neglect of primary care. Omphalitis can affect the animal in a multisystemic way, compromising its well-being and bringing economic losses. In treatment, the use of antimicrobials does not always solve the problem. Thus, surgical treatment can be used, which has good results and should be the choice in the disease. The objective of this work is to report 30 cases of omphalitis in calves, submitted to surgical or conservative treatment. Thirty cases of omphalitis in calves treated in the routine of the Veterinary Hospital of the Paranaense University was analyzed. On physical examination, the animals presented fever, apathy, hyporexia or anorexia and increase of umbilical volume, usually with purulent secretion. Some animals had sepsis and arthritis. In animals with sepsis, hyperemia of the episcleral vessels, dehydration and severe apathy were observed. In calves with arthritis, increased joint volume, pain on palpation and lameness were observed. In animals where the owners did not authorize the surgery, treatment was instituted with sulfadoxine and flunixim meglumine. In dehydrated calves, fluid therapy was used. Animals that were surgically treated received the same clinical treatment protocol as non-operated animals. The surgical procedure was performed under general anesthesia and consisted of resection of the affected umbilical structures. Omphalophlebitis was the most common illness. The most frequent complication was sepsis. Calves treated surgically had a higher survival rate (86.66%) than those treated clinically (46.67%). The clinical signs presented by all animals converged with the literature, allowing for clinical diagnosis. Clinical examination is essential for diagnosis in omphalitis cases. Complementary methods include ultrasound, thermography and laparoscopy, which are important to identify changes in intra-abdominal umbilical structures. Accurate diagnosis of the involved structures was only possible in animals surgically, as well as alterations in organs such as the liver and bladder. There is great variability related to the umbilical structures involved, according to initial care, breeds, seasonality or even the method of conception. Unlike what is observed in the literature, in the present study, there was a higher prevalence of omphalophlebitis, demonstrating variability in relation to the umbilical structures involved. Sepsis, observed in 16.7% of cases, results from bacterial ascension of the umbilical structures. Lameness due to polyarthritis was found in 10% of animals. Meningoencephalitis was observed in 3.3%. Hepatic and retroperitoneal abscedation were observed in 6.7% and 3.3% of cases, respectively. Conservative treatment with antibiotics and local antiseptics has a limited effect on this type of condition, which was proven in the present study, since the survival rate was statistically higher in animals surgically treated.(AU)

RESUMO

A pecuária de corte brasileira tem sido marcada por intensas transformações, resultantes da aplicação de técnicas modernas de produção, da utilização dos cruzamentos entre raças, e das exigências do mercado consumidor. O desempenho do período pré-desmama é importante por se tratar do primeiro resultado de produtividade animal e a classificação e tipificação das carcaças possibilitam enquadrá-las em diferentes classes e, assim, direcioná-las a diferentes mercados. O objetivo deste trabalho foi comparar o desempenho pré-desmama e características de carcaças entre dois grupos genéticos: Nelore (NE), e ½ sangue Angus-Nelore (F1), os quais foram abatidos sem castração e suplementados a pasto do nascimento ao abate. Foram tomados, ao acaso, 36 animais sendo 18 machos da raça Nelore (NE) e 18 machos oriundos do cruzamento industrial entre Nelore e Angus, machos (F1), sendo todos submetidos ao mesmo manejo e abatidos sem castração, com idade aproximada de 20 meses. Durante o processo de abate, as carcaças foram classificadas e tipificadas. O grupo F1 foi superior ao grupo NE com diferença significativa referente ao peso ao nascer (p=0,0046), peso ajustado aos 205 dias (p=0,0002), peso ao desmame (p=0,0005), ganho de peso diário entre o nascimento e os 205 dias (p=0,001). Quanto às características de carcaças não houve diferença estatística entre os grupos (p>0,05), sendo que, ambos atingiram a exigência frigorífica para espessura de gordura. Observou-se uma superioridade nos animais F1 quanto ao desempenho pré-desmama, e nota-se a possibilidade de terminar animais inteiros a pasto, com acabamento de carcaça mínimo, desde que bem alimentados.


The Brazilian beef cattle industry has been marked by dramatic changes resulting from the application of modern production techniques, use of crossbreeding and consumer market requirements. The performance of the pre-weaning period is important because it is the first result of animal productivity, and the evaluation and classification of carcasses enable their categorization into different classes, and thus, their directing to different markets. The objective of this study was to compare the pre-weaning performance and carcass traits between two genetic groups: Nellore (NE) and Angus-Nellore crossbreed (F1), which were slaughtered without castration, receiving grazing supplementation from birth to slaughter. Thirty-six animals were randomly selected, 18 Nelore (NE) and 18 Angus-Nellore crossbreed (F1) animals, all males, submitted to the same management system and slaughtered without castration, with approximate age of 20 months. During the slaughtering process, carcasses were classified and typified. The F1 group was superior to the NE group with significant differences related to birth weight (p = 0.0046), weight adjusted to 205 days (p = 0.0002), weaning weight (p = 0.0005), daily weight gain between birth and 205 days (p = 0.001). Regarding carcass traits, there was no statistical difference between groups (p> 0.05), and both reached the requirement for fat thickness. F1 animals were superior in relation to pre-weaning performance, and there is possibility to slaughter whole animals on pasture, with minimal carcass finishing if well fed.

El desempeño del período pre destete es importante por tratarse del primer resultado de productividad animal, la clasificación y tipificación de los esqueletos posibilitan encuadrarlos en diferentes clases y, así, dirigirlos a diferentes mercados. El objetivo de esa investigación ha sido comparar el desempeño pre destete y características de esqueletos entre dos grupos genéticos: Nelore (NE), y ½ sangre Angus-Nelore (F1), los cuales fueron abatidos sin castración y suplementados a pasto desde el nacimiento al abate.

Durante el proceso de abate, los esqueletos fueron clasificados y tipificados.

Sobre las características de esqueletos no hubo diferencia estadística entre los grupos (p>0,05), siendo que, ambos alcanzaron la exigencia frigorífica para espesor de grasa. Se observó una superioridad en los animales F1 en el desempeño pre destete, y se nota la posibilidad de terminar animales enteros a pasto, con terminación de esqueleto mínimo, desde que bien alimentados.
