of ultrasonographic diagnostics of pregnancy in bitches depending
on the first mating -
Vet World. 2008; 1(10): 293-295
aim of the present study was to follow up the potential of routine
ultrasonographic diagnostics of pregnancy in bitches depending on
the first mating. The experiments were performed on 32 bitches.
Pregnancy was detected using transabdominal ultrasonography with
Siemens sonoline adara equipment and a covex 5 MHz probe.
Subsequent serial examinations were made to sonographically
characterize normal canine prenatal development based about the
first mating. An enlarged uterus, gestational sacs and fetal poles
were recognized as the features of early bitchs pregnancy and were
first seen at 16 and 21 days, respectively. Cardiac activity was
detected earliest on gestational day 22 and recognizable canine
fetal morphology appeared at day 28. Generalized fetal movements
were first noted at day 28.
Key words: pregnancy,
bitch, ultrasound, mating
