Biobest Laboratories Ltd

Bird Sexing

Biobest Diagnostics (formerly Angen) provides specialist Avian DNA sex testing and diagnosis services to bird owners and veterinary surgeons. We are the only laboratory conducting these tests in the UK - we do not refer samples overseas.

The sexing PCR detects DNA sequences in the avian sex chromosomes. Cock birds are ZZ, and hen birds ZW. We have developed two slightly different methods based on this difference, which allow us to test most species of birds successfully. To view the complete list of avian species which we have successfully sexed to date please click here. If you have a species which is not on this list please contact us to discuss your options.
