Abstract(s)
O diagnóstico do sexo do feto equino pode ser realizado através ultrassonografia transrectal ou
transabdominal. Por via transrectal, o diagnóstico é feito no início da gestação pela localização do
tubérculo genital, caudalmente à inserção do cordão umbilical nos machos, e ventralmente à cauda nas
fêmeas.
Entre o dia cem e o dia duzentos e vinte de gestação, o sexo pode ser determinado por via
transabdomnial. A identificação dos machos é realizada principalmente através da observação do pénis
e nas fêmeas através da visualização das glândulas mamárias e tetos associados.
A viabilidade fetal pode ser avaliado pelas mesmas duas abordagens. Os principais parâmetros
encontrados incluem o diâmetro ocular fetal, atividade fetal, frequência cardíaca fetal, diâmetro aórtico
fetal, integridade do cordão umbilical, espessura combinada uteroplacentária, qualidade e quantidade
dos fluidos fetais. Esta avaliação permite identificar algumas anomalias e, assim, tomar as medidas
adequadas para assegurar uma boa gestação e viabilidade fetal e pós-natal do poldro.
Diagnosis of the sex of the equine fetus can be performed by transrectal or transabdominal ultrasound. By transrectal route, the diagnosis is made at the beginning of pregnancy by the location of the genital tubercle, caudally to the insertion of the umbilical cord in males and ventrally to the tail in females. Between one hundred and two hundred and twenty days of gestation, sex can be determined transabdominally. The identification of males is carried out mainly through the observation of the penis and in females through visualization of the mammary glands and associated teats. Fetal well-being can be assessed by the two ways. The main parameters observed include fetal ocular diameter, fetal activity, fetal heart rate, fetal aortic diameter, umbilical cord integrity, uteroplacental combined thickness, fetal fluids quality and volume. It permits to identify abnormalities and allow taking appropriate measures to ensure a good pregnancy and fetal and post-natal viability.
