Sex selection = more heifers, improved animal welfare and greater genetic gain

Through the Dairy Futures CRC’s Sexed semen program, researchers are developing new cost-effective technology to overcome the conception limitations of existing sex-selection technology.

“Sex selection of sperm for female-only births not only improves animal welfare through less unwanted males calves, but also increases the rate of genetic gain by allowing greater heifer selection opportunities.”

Sexed semen — program aims

Existing sex-selection technology has significant limitations due to reduced conception rates. Dairy Futures CRC researchers are applying a two-stage approach to the problem that will:

  • Produce a cost-effective solution, which can be adapted to current management practices, that delivers a 70:30 female:male ratio.
  • Develop a longer-term solution using stem cell technology that has the potential to deliver a 100% female result.

Collaborative approach

All projects in the Sexed semen program involve partnership between research providers and end-user organisations. Organisations that are involved in this program include:

Dairy Australia Monash University
