The recently-developed technique can help farmers tell the sex of a chick without cracking an egg.
new study
from researchers at the University of California, Davis and a startup company at the university called Sensit Ventures Inc., it is possible to sniff out the egg’s volatile organic chemicals and determine the egg’s sex. The team first had to find out if the chemicals released by male and female embryos give off reliably detectable differences. Atat the UC Davis Department of Mechanical and Aerospace Engineering, the team developed sensing chip technology that can collect and analyze organic chemicals in the air.
They adapted suction cups that are already used for industrial handling of eggs to “sniff” air from the eggs without actually opening them up. Gas chromatography and mass spectrometry analyzed the air samples and the sex of the eggs was confirmed by DNA analysis at the UC Davis Department of Animal Science.
“We think that the hardware platform invented at UC Davis could be integrated into hatcheries,” Turpen said.Laura is a science news writer, covering a wide variety of subjects, but she is particularly fascinated by all things aquatic, paleontology, nanotechnology, and exploring how science influences daily life.
