Multi-country metabolic signature discovery for chicken health classification.

Introduction: To decrease antibiotic resistance, their use as growth promoters in the agricultural sector has been largely abandoned. This may lead to decreased health due to infectious disease or microbiome changes leading to gut inflammation.

Objectives: We aimed to generate a m/z signature classifying chicken health in blood, and obtain biological insights from the resulting m/z signature.

Metabolic fingerprinting reveals extensive consequences of GLS hyperactivity.

Background: High glutaminase (GLS;EC3.5.1.
