Background
Maturity of intestinal functions is critical for neonatal health and survival, but comprehensive description of mechanisms underlying intestinal maturation that occur during late gestation still remain poorly characterized. The aim of this study was to investigate biological processes specifically involved in intestinal maturation by com...
La production de viande à moindre coût nécessite de disposer d’animaux robustes, efficaces, capables de s’adapter aux contraintes d’élevage. Ceci requiert l’évaluation de la capacité de l’animal à constituer et restituer ses réserves énergétiques. Ce travail de thèse a donc pour objectif d’identifier de potentiels biomarqueurs sanguins en lien avec...
The molecular mechanisms underlying feed efficiency need to be better understood to improve animal efficiency, a research priority to support a competitive and sustainable livestock production. This study was undertaken to determine whether pig blood transcriptome was affected by differences in feed efficiency and by ingested nutrients. Growing pig...
Primer sequences used for analysis of gene expression by qPCR.

Probes expressed in whole blood of pigs selected for low or high residual feed intake (RFI) fed a low-fat, low-fiber (LF) or high-fat, high-fiber (HF) diet, with significant interaction between line and diet.

A better understanding of the control of body fat mass and distribution is required for both human health and animal production. The current study investigates plasma parameters in response to changes in body fat mass.
Pigs from two lines divergently selected for residual feed intake were fed diets contrasted in energy sources and nutrients. Betwee...
The increasing use of unconventional feedstuffs in chicken’s diets results in the substitution of starch by lipids as the main dietary energy source. To evaluate the responses of genetically fat or lean chickens to these diets, males of two experimental lines divergently selected for abdominal fat content were fed isocaloric, isonitrogenous diets w...
The increasing use of unconventional feedstuffs exhibiting high fibre content in broiler's diets results in thesubstitution of starch by lipids as the main energy source. To evaluate the adaptability of genetically fat or leanbroilers to such diets, 48 male chickens were fed isoenergetic and isoproteic diets with high (8%, HL) or low(2%, LL) lipid...
With the aim to improve livestock production efficiency, thereis a need to gain insights into the molecular mechanisms underlyingfeed efficiency. There is increasing evidence that wholeblood may provide valuable insight into whole-body energyhomeostasis. The current study was undertaken to determinewhether pig blood transcriptome was affected by ge...
Adipose tissue mass is an important trait to be considered for pig production efficiency. Research work related to obesity indifferent species suggests that blood biomarkers of lipid metabolism can be found. The aim of the current study was to identifywhole blood molecular indicators associated with variations in adipose tissue mass in growing pigs...
Excessive deposition of body fat is detrimental to production efficiency. The aim of this study was to provide plasma indicators of chickens' ability to store fat. From 3 to 9 wk of age, chickens from 2 experimental lines exhibiting a 2.5-fold difference in abdominal fat content and fed experimental diets with contrasted feed energy sources were co...
Selection for high prolificacy and lean growth rate in swine has been associated with a substantial increase in piglet mortality. The first 24‐48 hours after birth represent a critical period for survival. A major determinant for early survival is piglet maturity at birth which relies greatly on the process of tissue maturation during the last mont...
