Preg-Tone
The Preg-Tone ultrasonic device emitted sound waves in the high frequency range, which means ultrasound.
The unit measures the amnion fluid which fills the uterus after insemination. The head has to be
held on the right side and the ultra sound will be reflected from the fluid. If the uterus does not contain
amnion fluid no reflection will be received and that means not pregnant. If the animal is pregnant, you
will hear a continuous tone. If the animal is not pregnant, you will hear an intermittent tone. So you can
clearly hear, if the animal is pregnant or not.
Place the head between the 2nd and 3rd teat, ca. 3 cm upwards and 45° angled ahead, so that you do
not meet the bladder. The sonar beam should pass the animal‘s spine 1 cm beneath, at the other side.
Keep the head good on the skin but not with too much pressure to avoid deforming at the body area.
Change also the direction of the beam so that you meet the whole uterus. No signal shows that a smooth
contact has not been made. If you place the head too far backward the possibility of meeting the animals
bladder is given. This can cause false result because the urine reflects. If you are not sure, please repeat
the test after the animal has drained its bladder.
