Biochemical and proteomic analyses of the physiological response induced by individual housing in gilts provide new potential stress markers

Abstract

The objective assessment of animal stress and welfare requires proper laboratory biomarkers. In this work, we have analyzed the changes in serum composition in gilts after switching their housing, from pen to individual stalls, which is generally accepted to cause animal discomfort.
