A fundamental issue of farm animal welfare is to keep animals clinically healthy, without disease or stress, particularly
in intensive breeding, in order to produce safe and quality food. This issue is highly relevant for the food industry
worldwide as they are directly linked to public health and welfare. The aim of this review is to explore how proteomics
can assess and improve the knowledge useful for the strategic management of products of animal origin. Useful indications
are provided about the latest proteomics tools for the development of novel biotechnologies serving the public
health. The multivariate proteomics approach provides the bases for the discovery of biomarkers useful to investigate adaptation
syndromes and oxidative stress. These two responses represent the milestones for the study of animal welfare.
Moreover their implementation in the characterization and standardization of raw materials, process development, and
quality and safety control of the final product of animal origin represents the current frontier in official surveillance and
