Neste presente relatório encontram-se descritas e caracterizadas as atividades desenvolvidas durante o estágio em clínica e cirurgia de bovinos de leite, contemplando também uma revisão bibliográfica sobre os fatores predisponentes de torção uterina (TU) em bovinos de leite. Foram recolhidos dados relativos à condição corporal (CC), número de partos, sentido da torção uterina, grau da torção e método de correção da mesma de 58 vacas assistidas com torção uterina, selecionadas aleatoriamente. Para além disto, foram recolhidos dados do feto proveniente destes casos de distócia, nomeadamente a apresentação no canal do parto, o sexo e a viabilidade. Correlacionaram-se algumas destas variáveis para testar hipóteses descritas na bibliografia. Verificou-se a existência de relação entre o grau da TU e a viabilidade fetal; entre o grau da TU e técnica de resolução executada e por fim entre a viabilidade fetal e a técnica de resolução aplicada. Verificou-se que a maioria das vacas que desenvolveram TU eram multíparas, sendo mais frequente durante o terceiro parto. Foi também possível observar que a maioria das TU ocorreram no sentido anti horário (esquerda em vista caudal) e entre 180º e 270º; Clinics and reproduction of dairy cattle Abstract: This report describes and characterizes the activities developed during the internship in clinical practice and surgery of dairy cattle. It also includes a literature review on the predisposing factors of uterine torsion (UT) in dairy cattle. Data was collected on body condition score (BCS), number of births, direction of uterine torsion, degree of twist, correctional method thereof and the survival of 58, randomly selected, cows assisted with UT. In addition, fetal data was collected from these cases of dystocia, in particular the presentation of the fetus in the birth canal, sex and viability. Some of these variables were correlated in order to test hypothesis described in the bibliography. A relationship was found between the degree of UT and fetal viability; between the degree of UT and the correctional method applied and finally between the fetal viability and correctional method applied. It was found that the majority of cows that had UT were multiparous, with UT being more frequent during the third birth. It was also possible to observe that the majority of UT’s that occurred were anticlockwise (left from the caudal view) and between 180º and 270º.
