Triplets at about 2 Months.
Three amniotic vesicles. Gestational age approximately 2 months. An ultrasonogram with a sector scanner would permit counting of fetuses and thus adjustment of the nutrition for ewes carrying multiples.
Smith MC (2006)
Fetus - 81 Days.
Crown Rump length of 8 cm at 81 days of gestation.
Shipley C (2006)
Ultrasound Unit.
Ultrasound unit with a transrectal probe primarily for pregnancy diagnosis.
Shipley C (2006)
Transabdominal Ultrasound.
The ewe may be placed on her rump while the transducer scans the lower abdomen for the presence of the fetus or fetuses and fetal fluids.
Drost M (1980)
Rectal Abdominal Palpation 1.
With the ewe in dorsal recumbency, a 15 cm diameter rod is gently inserted into the rectum. Proper restraint is essential. The potential for rectal trauma is considerable. The procedure is no longer recommended.
Hulet CV (1972)
Rectal Abdominal Palpation 2.
The rectal probe is angled upwards towards the udder. When the ewe is pregnant, the rod presses the gravid uterus against the ventral abdominal wall where it can be identified by the hand of the operator which has been placed on the abdomen in front of the udder.
Hulet CV (1972)
Rectal Abdominal Palpation 3.
When the ewe is not pregnant (or very early pregnant) the firm rod can be distinctly felt below the abdominal wall in front of the udder.
Hulet CV (1972)
