HK pregnancy test for swine

HK Pregnancy Testers for Pigs
You can quickly and reliably detect pregnant sows using the
pregnancy tester between the 28th and 75th day after the last
insemination with over 90 % certainty.
Usage:
After applying the contact oil, the probe is directed around
5 - 6 cm above the teat line, in front of the second teat from
the back, at a 45 º angle upwards against the sow’s body.
Gently moving the probe back and forth on the contacted
skin area helps you detect the central region of the
abdominal cavity.
