Resumo
Esta dissertação foi realizada no âmbito da conclusão do Mestrado Integrado em
Medicina Veterinária da Universidade Lusófona de Humanidades e Tecnologias e teve como
propósito o desenvolvimento do tema Partos distócicos em Bovinos de Carne. Reúne uma revisão bibliográfica extensa sobre o tema e uma apresentação e discussão de quatro casos
clínicos.
Um parto distócico pode ser definido como um parto difícil, que possa reduzir o potencial
reprodutivo materno e a viabilidade fetal. Do ponto de visto clínico, as causas da distocia podem ter origem fetal, materna ou feto-materna, sendo imprescindível que todas as causas físicas e/ou fisiológicas que impedem a sua progressão normal, sejam diagnosticadas e corretamente
resolvidas.
Um parto distócico pode representar elevadas perdas económicas diretas para os
produtores sendo por isso, fundamental adotar um conjunto de medidas preventivas, de modo
a promover o desenvolvimento reprodutivo das explorações, e como efeito, um aumento na
produtividade, rendimento e bem-estar animal.
Nesta dissertação, são apresentados quatro casos clínicos de partos distócicos em
bovinos de carne, os quais foram selecionados de forma que fosse possível demonstrar as distintas formas de apresentação e abordagem de um parto distócico em vacas. Relativamente as causas de distocia, a desproporção feto-materna e a incorreta disposição fetal representam um número significativo na amostra de casos observados durante período de estágio, pelo que,
o grande desafio destes pacientes estará relacionado com a precocidade do diagnóstico, no
maneio efetuado e na capacidade de manter os produtores interessados na aplicação de
medidas preventivas através da criação de protocolos e formações dirigidas aos mesmos.

This dissertation was carried out within the scope of the conclusion of Integral master’s in veterinary medicine at Univesidade Lusófona de Humanidades e Tecnologias de Lisboa and with the purpose of developing the theme of dystocic parturition in bovines. It brings together an extensive literature review on the topic and presentation and discussion of four clinical cases. A dystocic parturition can be defined as a difficult parturition, that can reduce the maternal reproductive potential and even decrease fetal viability. From a clinical point of view, the causes of dystocia can be classified according to their origin as fetal, maternal or fetal-maternal, and it is essential that during the first and second stages of labor, all physical and/or physiological causes that impede its normal progression, are diagnosed and correctly resolved. A dystocic parturition can represent high direct economic losses for producers. Therefore, it is essential to adopt a set of preventive measures, in order to promote reproductive development on farms, as well as increase productivity, income, and animal welfare. In this dissertation, four clinical cases of dystocic parturition in bovines are presented, which were selected in order to demonstrate the different approaches of a dystocic parturition in bovines. Regarding the causes of dystocia, maternal-fetal disproportion and incorrect fetal disposition represent a significant number of cases in the sample observed during the internship period, meaning that, the great challenge of these animals will be related to the precocity of the diagnosis, their living conditions, and in the ability to keep producers interested in the application of preventive measures through the creation of protocols and training. Keywords: dystocia; parturition; bovines; economic impact; calf
