Pregnancy Scanning of Goats
Goats may be scanned for pregnancy testing from six weeks (42 days) after the billy is removed. Animals are ultra sounded externally using a BCF ultrasound unit.
Pregnancy Scanning Options
Pregnant or empty only (wet or dry)
Nannies can be tested for pregnancy from six weeks after the billy being removed to full term
Foetuses May be split between the joining period into early or late pregnancy. For the most accuracy the billy should be in for no longer than 70 days (10 weeks) with scanning occurring 42 days (6 weeks) from the billy coming out.
For the most accurate twinning nannies should be scanned from 42 days (6 weeks) to 105 days (15 weeks). Before this time pregnancies may not be seen by the ultrasound and after this time lambs are too large to tell apart and separate.
For the most accurate triplet scanning nannies should be scanned from 42 days (6 weeks) to 84 days (12 weeks). Before this time pregnancies may not be seen by the ultrasound and after this time lambs are too large to tell apart and separate.
Electronic tags may be scanned to identify pregnancy status with a file available on completion of scanning.
Nannies are to be either yarded or kept in a bare holding paddock the night before for ease of handling when scanning occurs.
Identifying Pregnant Nannies
Nannies can be identified in two ways during scanning either via a spray raddle or a 5-way draft may be setup at the end of the scanning race.
All equipment used is washed and disinfected via a self-contained wash-down unit upon completion of each job to prevent disease transfer between properties.
