Scientists expect to revolutionise animal genetic improvement programs after successfully integrating molecular marker technology with novel reproductive technologies.

The combined package, developed by CSIRO Tropical Agriculture, was announced at the CSIRO Industry Colloquium held in Rockhampton on 28 November.

Dr Gerard Davis of CSIRO Tropical Agriculture said the technology, known as SMART (Selection with Markers and Advanced Reproductive Technologies) breeding, is at the forefront of breeding technology.

He said at the moment, genetic analysis in cattle can identify gene markers for production and product quality traits. These can be used as predictors of the future performance of a bull or heifer, or their progeny.

"Since the genetic makeup of an animal remains fixed from the time of fertilisation, gene marker testing can even be applied to embryos."

He said novel reproductive technologies make it possible to produce embryos from heifer calves. These embryos can undergo genetic diagnosis for sex, inherited disorders and gene markers for specific traits.

Used in combination, these technologies have the ability to significantly enhance breeding programs. Preliminary calculations show the technology may lead to a six fold faster genetic progress.

Applications include rapid multiplication of individual animals of particular genetic merit, and efficient selection between and within families, lines or breeds.
