Abstract

Proteomics is a set of molecular biology tools of utmost significance in life sciences. Over the last 40 years, its usefulness has been demonstrated in different scientific fields. Specifically concerning domestic and wildlife species, proteomics use has been hindered by several factors: technical difficulties inherent to the lack of databases specific to such animal species and a general lack of knowledge on principles and applications of proteomics by researchers in these fields. Our research group has been using proteomics as a research tool to study the physiology of domestic animals over the last 20 years, effectively complementing classical animal science studies. In this talk, we retrospectively address some of such examples: the use of algae as alternative feedstuffs in piglets, tolerance to seasonal weight loss in dairy goats and difference between male and female muskox (Ovibos moschatus) proteomes of different tissues. In all examples, we delve into the rationale behind each subject, its main results and accomplishments allowed by proteomics. We make some considerations on how the use of proteomics may become more accessible to a broad scientific audience, particularly through infrastructure projects like the recent EPIC-XS. We conclude that Proteomics is a tool of the utmost interest in this very particular research field and that its use should be fostered by research collaboration, particularly between research groups in animal sciences and proteomics platforms.
