A new system for effectively and efficiently sampling and analyzing blood from livestock has been developed by engineering professor Suresh Neethirajan. Known as Lab on a Chip, the tiny, field-deployable system is directed at testing specifically for subclinical ketosis. This condition puts cows at risk of ketosis, a disease that reduces fertility and milk production. The system was developed in the University’s BioNano Laboatory where Neethirajan is the principal investigator. Lab on a Chip will be site-tested in 2015 at the Livestock Research and Innovation Centre – Elora Dairy Facility.
