Serum-based metabolomics characterization of pigs treated with ractopamine


ABSTRACT: A study was performed to determine if serum-metabolomics could be used to establish a predictive tool for identifying ractopamine misuse in pigs. Ractopamine, a beta-agonist used as growth promoter in livestock, is with great controversy, and it has been forbidden in most countries worldwide. However, due to economic benefits, the possibility of widespread abuse of ractopamine still exists. “Omics” strategies, based on the observation of physiological perturbations, are promising approaches to tackle drug misuse in breeding animals. In this context, our aim was to set up a high performance liquid chromatography - high resolution mass spectrometry (HPLC-HRMS) based metabolomics workflow for screening pig serum for ractopamine administration. Therefore, an untargeted metabolomics approach was developed to characterize and compare serum metabolic profiles from control and treated pigs. Two different extraction strategies were investigated, and the results showed that the combination of methanol extraction and methanol-water extraction protocols significantly improve the metabolites coverage. A two-level data analysis using univariate and multivariate statistical analyses was carried out to establish descriptive and predictive models, which enabled the discrimination of treated animals from control animals and highlighted a number of candidate biomarkers that contributed the most in the observed discrimination. This research indicates that metabolomics approach can be considered as a powerful strategy to highlight biomarkers related to ractopamine treatment in pig which may subsequently be implemented as screening strategy to predict for such illicit practices.
