Tracing (r)bST in cattle: Liquid-based options for extraction and separation. “Journal of Liquid Chromatography & Related Technologies”, vol. 40(11), 541-5481082-6076http://hdl.handle.net/10347/16238Growth hormone (GH) or somatotropin (ST) is a species-specific polypeptide hormone produced in the pituitary gland of vertebrates. When administered exogenously to dairy cattle, it has galactopoietic effects and is capable of increasing the milk yield. Recombinant bST enabled large-scale applications in farms, enhancing significantly milk production. While it is banned in the European Union (EU), several countries permit the trade and use of recombinant somatotropins in animal husbandry. In this context, effective analytical methods are needed for residue control to avoid an illegal use of rbST but also to prevent fraudulent labeling in some cases. The present review includes studies published in the last 5 years (from 2012 to 2017) to monitor rbST in bovine animals, using liquid-based applications. It is then intended to serve as a practical guide to help those laboratories interested in developing analytical methods to detect rbST use and abuseeng© 2017 Taylor & Francis GrouprbSTBovineSomatotropinLiquid chromatographyExtractionSeparationCattleMaterias::Investigación::33 Ciencias tecnológicas::3309 Tecnología de los alimentos::330915 Higiene de los alimentosjournal article10.1080/10826076.2017.13314531520-572Xopen access
