Sensors for early detection of diseases in calves created in Voronezh

Scientists from the Voronezh State University of Engineering Technologies have developed sensors that allow early detection of respiratory diseases in cattle by a swab from the nose of an animal, according to a press release from the Russian Science Foundation (RSF).

“We have developed a simple non-invasive technique that can quickly detect respiratory infections, significantly simplify the diagnosis of diseases and allow earlier treatment of sick calves. This will improve the quality and quantity of MILK and MEAT received on farms, prevent both the death of cattle and costs for his treatment," Anastasia Shuba, Ph.D.

The sensors analyze the volatile compounds contained in the nasal mucus, and with high accuracy determine changes in their composition, indicating diseases. To analyze the full complex of these volatile substances, chemists designed 16 sensors with various coatings of polymers and nanomaterials, which are able to absorb biomarkers of respiratory diseases with the greatest efficiency.

The results of the study are published in the journal Veterinary Sciences. it was supported by a grant from the Russian Science Foundation.
