cycling level
which (2) animals do ultrasonography on both rectal

- mare
which (4) animals do ultrasonography on abdominal probe
- pig
- ewe
- dog

c. dog, cat

post mating
a. cow = 13 days
b. mare = 9-16 days
c. dog, cat = 28 days
d. pig = 25-70 days

SOW
this pregnancy diagnosis, it is more commonly used than ultrasound in farms because it is less expensive
dopplers
pregnancy diagnosis that detects:
1. increased blood flow in uterine arteries
2. fetal heartbeats
3. umbilical artery pulsation
4. fetal movement
dopplers
Position of Medata Probe (pigs):
medial to stifle skin fold in a vertical level
with the 2nd from the last teat
Uterine arteries
pulsation
Position of Medata Probe (pigs):
a. 1st 1/2 pregnancy: probe pointed dorsally (level of 3rd from last teat)
b. Late pregnancy: probe pointed dorsally on the boundary of mammary gland (level of 3rd or 4th from last teat)
Fetal heartbeat
Position of Medata Probe (pigs):
probe pointed dorsally on the boundary of mammary tissue (level of 3rd or 4th from the last teat)
Fetal movement
Some dopplers can detect the _____ fluid in pregnant animals.
