Global Reproduction Solutions (GRS) offers an on farm embryo transfer (ET) service for cattle breeders across Australia. We regularly visit farms in various states around the country, servicing both dairy and beef clients. We provide our clients with an easy to read yet detailed program to follow and we take the time to discuss each donor’s flush history or expected results. We try to set a program to maximize results whilst ensuring the on-going viability of the donor being flushed.
GRS is also able to offer an on-centre environment at Goorambat for beef donors and dry dairy cows or heifers. Each donor is routinely checked to ensure that they are ready to be flushed and enter a program with a specifically designed, controlled, nutritional protocol to maximize results. We set up and run the programs personally, ensuring the AI is done on time, at the right time.
We are also able to set up and run recipients to transfer embryos fresh on the day of flushing. This is a great advantage to many breeders who may not have enough recipients of their own or who do not have the time or ability to run their own recipients.
GRS are experienced in the art of embryo splitting. This is an added advantage to breeders looking to maximize the number of pregnancies from fresh transfers. Embryo splitting is performed by taking a fine blade and splitting suitable embryos into 2 demi embryos. Each of these demi embryos are transferred fresh into suitable recipients. Experience has shown that the subsequent pregnancy rate is between 100 and 120% of the original number of embryos split.
GRS have been sexing embryos for a number of years and is the only Australian based company offering this service on a regular basis. We use a Y chromosome specific PCR based process that was originated by Dr C Herr. The process works by taking a small 6-10 cell biopsy off suitable embryos on flush day, adding YCD and running the biopsy through a DNA amplifier then through an agarose gel. The embryos can be frozen for later transfer or placed in recipients on the day of flushing. This service is used by a number of our dairy clients who are looking to increase the number of heifer calves.
GRS runs a Department of Agriculture accredited embryo export facility, allowing clients with overseas interest to be able to meet demand for their genetics. We have been exporting bovine embryos to countries including New Zealand, Canada, USA, the EU and China, spreading the best of Australian bovine genetics across the world.
We also work in close conjunction with Dave and Roz Kennett of Genstock NSW, who run an ovine embryo export facility, and have been able to meet demand for ovine and caprine embryos to many different countries.
