RESUMO

Fraturas ósseas e luxações são mais comuns em animais jovens e, na maioria das vezes, essas fraturas ocorrem devido ao manejo incorreto desses animais, podendo levar a uma queda de produção a curto ou longo prazo, gerando perdas econômicas e produtivas de animais de alto padrão genético. Nesse contexto, o objetivo deste trabalho foi relatar a ocorrência de uma fratura na região metacarpiana do membro torácico esquerdo de uma bezerra Gir de 12 dias de idade, causada por uma contenção ineficaz durante a pesagem. O animal proveniente de uma fazenda em Umirim/CE foi encaminhado ao Hospital Veterinário de Grandes Animais do Centro Universitário INTA em Sobral/CE. Ao passar pelo exame radiográfico, foi constatada a fratura na região metacarpiana do membro torácico esquerdo. O animal foi imobilizado de forma manual, seguindo-se métodos semiológicos para minimizar o estresse. Para a imobilização do membro, foi utilizada a muleta de Thomas modificada e bandagens, associadas ao controle da dor com as drogas Flunixin meglumine (1,1mg/kg) e Fenilbutazona (4,4mg/kg). Depois da imobilização, o animal seguiu internado no HOVET-GA e, após 18 dias, foi realizada uma nova radiografia para ver o progresso a partir do tratamento adotado. Constatou-se a formação de um calo ósseo, com a ossificação da fratura, não sendo necessário o encaminhamento cirúrgico do animal. Assim, o tratamento com muleta de Thomas modificada foi efetivo para a recuperação do membro fraturado, além de ser um tratamento de baixo custo e fácil aplicação, tendo o animal apresentado uma boa resposta ao tratamento terapêutico para controle da dor.

Bone fractures and dislocations are more common in young animals and mostly occur due to incorrect handling of these animals, which can lead to a short or long-term drop in production, generating economic and productive losses of animals of high genetic standard. This study aimed to report the occurrence of a fracture in the metacarpal region of the left thoracic limb of a 12-day-old Gir heifer, caused by an ineffective restraint during weighing. The animal from a farm in Umirim/CE was sent to the Veterinary Hospital of Large Animals of the University Center INTA in Sobral/CE. The radiographic examination found a fracture in the metacarpal region of the left thoracic limb. The animal was manually immobilized following semiological methods to minimize stress. For the limb immobilization, a modified Thomas crutch and bandages associated with pain control with the drugs Flunixin meglumine (1.1mg/kg) and Phenylbutazone (4.4mg/kg) were used. After immobilization, the animal remained hospitalized at HOVET-GA and after 18 days a new radiograph was performed to evaluate the progress achieved with the treatment adopted. It was found the formation of a bone callus with the ossification of the fracture, not requiring the surgical referral of the animal. Thus, the treatment with the modified Thomas crutch was effective for the recovery of the fractured limb, in addition to being a low-cost and easy-to-apply treatment. The animal showed a good response to the therapeutic treatment for pain control.

RESUMO

A criação de bezerras é uma das fases mais importantes na bovinocultura leiteira e um manejo profilático em ambientes físicos de alojamento é crucial para evitar acidentes que possam comprometer a vida produtiva dos animais futuramente. O bezerreiro tropical é um dos alojamentos mais comuns utilizados no Nordeste brasileiro em grandes criações, possivelmente devido ao baixo custo. Diante disso, objetivou-se nesse trabalho relatar um acidente provocado por tropeço em fio extensor de superfície do bezerreiro tropical, no qual ocasionou um traumatismo tibial em uma bezerra Girolando de dois meses de idade. O atendimento ocorreu no Hospital Veterinário de Grandes Animais do Centro Universitário Inta (Uninta) em Sobral/CE e o animal foi proveniente de uma fazenda de alta produção leiteira da cidade de Umirim/CE. O exame clínico revelou que a região afetada foi próxima ao jarrete. O exame radiográfico constatou fratura na região epifisária da tíbia proximal. Após avaliação pela equipe clínica e cirúrgica, o paciente foi encaminhado para cirurgia de correção, mas antes foi estabelecida imobilização e bandagens para manter o membro afetado imóvel até a realização do procedimento cirúrgico. O tratamento clínico medicamentoso pós-cirúrgico foi conduzido, além de foram instituídos cuidados diários de limpeza do ferimento cirúrgico com antisséptico local. Após a realização da cirurgia de correção da fratura, estando o paciente estabilizado, este mesmo animal recebeu alta médica 17 dias depois da internação. Desta forma, o bezerreiro tropical está passando por mudanças estruturais e de manejo para evitar mais traumas provocados pelo tropeço, enroscamento e quedas das bezerras.

Calf rearing is one of the most important stages in dairy cattle and, prophylactic management in physical accommodation environments is crucial to avoid accidents that could compromise the productive life of these animals in the future. The tropical calf is one of the most common housings used in the Brazilian Northeast in large creations, possibly due to the low cost. This study aimed to report an accident caused by tripping over surface extender wire of the tropical calf, which caused a tibial trauma in a 2-months-old Girolando heifer. The attendance took place at the Veterinary Hospital for Large Animals of the Inta University Center (Uninta) in Sobral/Ce and the animal came from a high-production dairy farm in the city of Umirim/Ce. The clinical examination revealed that the affected region was close to the knuckle. The radiographic examination showed a fracture in the epiphyseal region of the proximal tibia. After evaluation by the clinical and surgical team, the patient was referred for corrective surgery, but before that, immobilization and bandages were established to keep the affected limb immobile until the surgical procedure was performed. The post-surgical medical treatment was conducted, in addition to the daily care of cleaning the surgical wound with local antiseptic. After the surgery, to correct the fracture with the patient stabilized, the hospital discharge occurred 17 days after hospitalization. Thus, the tropical calf, is undergoing structural and management changes to avoid further trauma caused by stumbling, tangling, and falling.

RESUMO

The aim of this work went to evaluate the spermatic morphology of ram semen cooled to 4 °C in nature (INCW) and in powdered coconut water (ACP-102®) during the rainy and dry season in the Northeast of Brazil. The semen of four rams was collected, divided into two fractions and diluted in INCW and ACP-102®. The samples were conditioned in refrigerator to 4 °C and after 2, 24 and 48 hours of cooling were submitted at thermo resistant test (TT). Semen slides were executed in the beginning and in the end of TT to evaluation of the spermatic morphology (SM). The SM parameters, within different preservation times (2, 24 and 48h) and extenders (INCW and ACP-102®), were expressed in media and standard deviation (SD) and submitted to Tukey test (p<0.05). According to the diluted samples in ACP-102®, was observed a percentage increase of morphology normal spermatozoon in the rainy season as was verified in the dry season. In conclusion, the ACP-102® extender present good preserve capacity. Agreed with this study, the raining season did not have influence on the characteristics of spermatic morphology.

RESUMO

Knowing the follicular dynamics and predicting the time of ovulation is fundamental to the success ofbreeding programs that use reproductive biotechnologies. The objective of this study was to characterize thefollicular dynamics of crossbred cows reared in the northern region of the Ceará state, Brazil, identifying themoment of ovulation and correlating the time of ovulation with the rectal temperature. According to the dataobtained, there was a time difference on the onset of estrus and ovulation period between the cycles analyzed inthe dry season (≈27 hours) and the rainy months (≈33 hours). In addition, rectal temperature tends to decreaseas ovulation approaches. These data show the importance of knowing the pattern of follicular dynamics toimprove the pregnancy rate of herds in different conditions.(AU)
