Open AccessSkeletal muscle metabolomics and blood biochemistry analysis reveal metabolic changes associated with dietary amino acid supplementation in dairy calves
The effects of different amino acid (AA) supplementations of milk protein-based milk replacers in pre-ruminant calves from 3 days to 7 weeks of age were studied. Animals were divided into 4 groups: Ctrl) Contr...

The Use of Proteomics to Study Biomarkers of Stress and Welfare in Farm Animals
Animal welfare and stress are important issues mainly because of public perception, marketing, product acceptance and production efficiency, quality and quantity. They are complex conditions that include physi...

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

Open AccessSerum haptoglobin dynamics in pigs vaccinated or not vaccinated against porcine circovirus type 2
The present work describes the serum haptoglobin (Hp) dynamics in piglets vaccinated and non-vaccinated with a commercial porcine circovirus type 2 (PCV2) vaccine at 3 weeks of age, and its relationship with t...

Neurotransmitter levels and proteomic approach in pig brain: pre-slaughter handling stress and cognitive biases
Stress can be defined as a brain-body reaction towards stimuli arising from the environment or from internal cues that are interpreted as a disruption of homeostasis. The organization of the response to a stre...

Targeted proteomics as a tool for porcine acute phase proteins measurements
It is mandatory, after protein identification, to validate candidate markers in a larger amount of samples for biomarker discovery. The most used methods for validation of new markers are enzymatic or immunoas...

The search of stress markers in porcine by using proteomics
Welfare problems are important for ethical reasons and because they may cause great economic losses. Nevertheless, objective laboratorial criteria to evaluate animal stress are still lacking. Several plasma co...

Oxidative stress and acute phase response associated to changes in housing from pen to individual stalls in reproductive sows
Under field conditions, gilts are usually housed in pens of 10–15 sows by group, when they arrive into the production facility from the multiplication unit. After spending there the quarantine period, they are...

Open AccessAssociation between plasma metabolites and gene expression profiles in five porcine endocrine tissues
Endocrine tissues play a fundamental role in maintaining homeostasis of plasma metabolites such as non-esterified fatty acids and glucose, the levels of which reflect the energy balance or the health status of...

Two forms of transforming growth factor-β distinguished by multipotential haematopoietic progenitor cells
Type-β transforming growth factors (TGF-βs) are polypeptides that act hormonally to control proliferation and differentiation of many cell types1,2. Two distinct homodimeric TGF-β polypeptides, TGF-β1 and TGF-β2...
