Pregnancy determination in does is commonly performed using real-time ultrasonography to visualize the presence of an embryo/fetus and placentomes within the uterus. Transabdominal ultrasound is quick and reliable and can detect pregnancy as early as 30 days, though it is most accurate after 45 days gestation.

Ultrasound scanning proves to be a low-cost, accurate method of determining pregnancy status, stage of pregnancy and litter size. By grouping animals according to pregnancy status, stage and/or litter size, managers can increase production efficiency, improve allocation of farm resources and improve the health and welfare of the flock/herd.

2024年12月29日 · Ultrasound can detect pregnancy in goats as early as 17–28 days postbreeding. During this period, transrectal ultrasound techniques are used to diagnose very early pregnancy. The transducer is inserted into the goat’s rectum, providing a clear view of the uterus and gestational sac.

2020年6月30日 · Ultrasonography (USG) for embryo-foetal foetometry is widely used in the management of goat breeding. Tissues and organs of the embryo/foetus are measured and evaluated to assess gestational age. Transrectal, transabdominal and transvaginal probes are used to perform the ultrasound examination.

2012年7月20日 · With advances in ultrasonography of small ruminants, assessment of pregnancy in goats is challenging for accurately managing reproduction. This article presents an up‐to‐date review of the use...

2023年2月9日 · The evolution of some fetal growth indices and arterial blood flow parameters in the umbilical cord of the embryos and fetuses of primiparous pregnant goats of Murciano-Granadina breed were analyzed by ultrasonography. Weekly ultrasonographic sessions took place from 18- to 125-days post-breeding. Fetal measures were carried out by ultrasound B ...

2015年7月9日 · 2D and 3D ultrasound were performed from day 20 to 120 of gestation, twice in week from day 20 to 60 and once in week from day 60 to 120 of gestation on six goats. The ultrasonographic images were obtained using Toshiba, Nemio-XG …

2019年3月15日 · Ultrasonography is a technique commonly used in veterinary reproduction in species including goats. Pregnancy in goats can be detected as early as the 16th day post-breeding via transrectal way. However, because of the early embryonic losses, it is recommended to delay the transrectal examination until days 32-34 of gestation.

1998年6月1日 · Detection of the caprine embryo by ultrasonography and confirmation of its viability by heartbeats was shown to be a reliable method for early pregnancy diagnosis in Anglo-Nubian goats. Ultrasonic measurement of crown-rump length was useful in …
