Advanced Breeding Services was established in October
1993 The partners were senior employees of Australian
Sheep Artificial Breeders (ASAB) and Southern Angora
Breeders (SAB) from 1978 to 1993, Bronte Mawson as
manager / embryologist and Dr. Lyn Davies as head
veterinarian. Both businesses developed as industry
leaders equipped to apply “new” artificial breeding
technology to emerging demand from specialist stud sheep
and goat breeders within the Australian livestock
During these formative years (1978 to 1993) the team
worked with Professor David Armstrong, Dr. Bob Seamark,
Dr Lou Warnes and Dr. Simon Walker, world leading
research scientists dealing specifically with artificial
breeding technology. The team worked on the development
of reliable super ovulation protocols, culture media and
techniques, embryo freezing and thawing, short term
embryo storage and experimental cloning work. The ABS
commercial programmes in those days were forefront
applications of very recent research and evolved into
robust procedures that have stood the test of time.
Some well recognized industry firsts developed from this
early research into embryo transfer and its commercial
application are listed below.
The team proved that twin transfers (as opposed to
single embryo transfers) increased conception rate and
embryo survival rate markedly.
Established a super
ovulation protocol using FSH-P that was far superior to
Defined the optimum
synchrony between embryo recipient and donor.
Initiated the use of
Hepes-SOFM as a culture media, semen diluent and buffer.
Hepes-SOFM used to culture
single cell embryos to blastosysts.
Hepes-SOFM used to store
embryos at 4ºC for 24-48 hours.
Developed strategies to
handle luteal failure in donors.
Developed commercial non
surgical embryo collections in Angora Goats.
protocols for synchronizing recipients.
Timed ovulation and
insemination in Merinos to achieve 90% plus
fertilization in ET.
Set high standards in
donor and recipient surgery and anesthesia.
During this time A.B.S operated
throughout SA, TAS, VIC, NSW and QLD with extensive
programs run in NZ and USA. Client programs varied from
the hobby farmer with two Angoras flushed to large
Merino businesses setting up 300 donors.
SAB positioned as the
major ET contractor at Kirra Quarantine Station SA for
the importation and expansion of Angora and Suffolk
genetics from the USA.
SAB was awarded the
contract to collect and freeze 1000 cashmere embryos in
Tasmania for export to USA.
ASAB set up the semen
processing laboratory and ET facility at Haddon Rig NSW
ASAB programmed 50 to 300
donor each year at Haddon Rig from 1988-93.
SAB organized all facets
of the AB programs toproduce 2000 Angora embryos in SA
for export to NZ and 2000 Angora and Cashmere embryos in
NZ for export to the UK.
SAB managed and operated
500 donor ET programs for Arpac International in SA and
Both businesses worked
with elite stud animals for the same clients year after
ASAB put in place the team
that produced the first cloned sheep in Australia.
SAB and ASAB always
produced consistent commercial results.
Today ABS is a small mobile team
geared to meeting the requirements of sheep and goat
breeders throughout Australia in AI, ET, embryo freezing
and thawing, and organizing the import and export of
