Australia’s Longest Serving Sheep Artificial Breeding Company
GENSTOCK is a family owned business and was established in 1984 by Craig and Elizabeth Heggaton. Craig was involved in the first commercial laparoscopic artificial breeding programme in Australia. GENSTOCK has always been in the forefront of sheep artificial breeding in Australia.
GENSTOCK is an approved Embryo and Semen Collection centre for Export. We have clients in many countries such as NZ, Uruguay, Cananda, USA and Argentina.
GENSTOCK has performed over 1,500,000 laparoscopic inseminations; 40,000 embryo transfer flushes and pregnancy scanned more than 10 million ewes.
Due to the advancement in technology and improvement in Australian standards in semen assessment, GENSTOCK averaged a 75% conception rate in the last season. In a single embryo transfer season, mature ewes averaged 7.5 pregnancies per donor flushed and maiden ewes (from 6 months of age) averaged 5.1 pregnancies per donor flushed.
