Effet des coproduits riches en fibres alimentaires sur l'utilisation disgestive et métabolique des minéraux chez le porc et le poulet by Marion Bournazel( )

1 edition published in 2017 in French and held by 1 WorldCat member library worldwide

L'optimisation de l'utilisation de phosphore reste un enjeu majeur pour assurer la durabilité de nos filières avicoles et porcines. Aujourd'hui, l'utilisation de coproduits, relativement riches en fibres alimentaires, est grandissante. Or, les fibres alimentaires sont reconnues pour moduler les processus de digestion et la digestibilité des nutriments. Ce travail de thèse a permis de progresser sur les mécanismes digestifs engendrés par l'apport de coproduits riches en fibres alimentaires et leurs effets sur la digestion des minéraux, en lien avec la phytase microbienne, spécifiquement chez le porc et le poulet. Leurs conséquences métaboliques en terme de balance minérale et d'équilibre acidobasique ont également été mises en évidence Les connaissances acquises vont contribuer à l'amélioration de l'apport en minéraux, notamment de phosphore et de calcium, dans des formules diversifiées chez le porc et le poulet. A terme, ceci permettra de mieux adapter nos systèmes d'alimentations au regard des enjeux de durabilité
Caractérisation fonctionnelle et biochimique des protéases et antiprotéases présentés dans le jaune d'oeuf "gallus gallus". by Marie Bourin( )

1 edition published in 2011 in French and held by 1 WorldCat member library worldwide

Le jaune d'œuf est une source de nutriments et de molécules bioactives pour l'embryon. Il renferme de nombreuses protéases et antiprotéases, dont la fonction reste méconnue. Notre objectif était d'identifier et de caractériser les protéases/antiprotéases associées spécifiquement à la formation du jaune d'œuf (vitellogénèse). Les précurseurs du jaune sont exprimés par le foie à la maturité sexuelle des poules. Par une approche transcriptomique, nous avons identifié 582 gènes, dont 15 protéases et antiprotéases, sur exprimés par le foie des poules sexuellement matures. Au moins trois d'entre elles sont présentes dans le jaune ou la membrane vitelline. Nous avons montré que l'expression de la « similar to nothepsin », une protéase prédite de fonction inconnue, était spécifique du foie des femelles et pourrait participer à la maturation des précurseurs du jaune. D'autre part, nous avons démontré que l'ovoinhibiteur, une antiprotéase du jaune, aurait un rôle dans la défense antimicrobienne de l'œuf. L'intégration de l'ensemble de ces résultats fournira des données essentielles relatives à la vitellogénèse et à la fonction des protéases/antiprotéases dans le jaune d'œuf
Biominéralisation de la coquille d'oeuf de poule : caractérisation des protéines de la matrice organique impliquées dans l'initiation de la minéralisation by Pauline Marie( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

The aim of this PhD was to identify and quantify eggshell organic matrix proteins which control polymorphic type and morphology of crystals at different time points of the eggshell mineralization process in order to highlight particular components involved in calcification at each calcification stage. A total of 64 and 175 proteins differentially abundant during mineralization process were identified in the forming milieu (uterine fluid) and in the eggshell organic matrix respectively. Out of them, 24 uterine fluid and 77 eggshell proteins are functionally related to the mineralization process. We paid particular attention to 20 overabundant proteins with direct or indirect functional evidences related to calcification. Further studies will be necessary to confirm their involvement in the chicken eggshell mineralization

Identification de gènes et de protéines de l'utérus impliqués dans le transfert minéral, la calcification de la coquille et la protection antimicrobienne de l'oeuf de poule by Vincent Jonchère( )

The chicken eggshell is a biomineral which protects the embryo during its development. The eggshell formation takes place in the hen's uterus. The eggshell mainly contains calcium carbonate (CaCO3) and a few amount of organic matrix. The eggshell formation required high calcium and bicarbonate ions, which are provided by important trans-epithelial transports through the uterine endothelium. The organic matrix plays an important role in the eggshell fabric and in the establishment of its remarkable mechanical properties.The aim of this PHD study was to identify the genes and proteins of the uterus, involved in the mineral transfer, the eggshell calcification and the antimicrobial protection of the egg. We have used cDNA microarrays to allow a global identification of genes specifically expressed in the uterus during the process of eggshell calcification. In this transcriptomic approach, we have used the spatial and temporal sequence of synthesis and secretions of the egg components along the oviduct. The expression of genes in the uterus was compared during the mineralization of the eggshell with magnum and isthmus tissues, which are involved in the egg white synthesis and the eggshell membranes deposit respectively. This study revealed 605 specifically over expressed transcripts in uterus, which are corresponding to 469 genes and 437 proteins. Uterine transcripts analysis highlighted an important over expression of genes coding ion transports and ion binding proteins. The transcriptomic approach also revealed 54 proteins with a signal peptide, potentially secreted to be deposited in the eggshell to play a biological role. These 54 secreted proteins were classified according to their putative biological functions using protein databases and bibliographic data. Among these proteins, many exhibited calcium and ion binding properties, and consequently could be implied in the control of the eggshell mineralization. Several proteins also present antimicrobial activities. A third group of proteins consists of proteases and anti-protease, which could play a crucial role in the control of the biomineralization of the eggshell. Finally, a group of proteins might be involved in proper folding of the eggshell matrix proteins, which is important to ordered mineralization. The transcriptomic approach also allowed the identification of new proteins involved in uterine trans-epithelial ion transports. Their involvement in supplying eggshell precursors was confirmed by comparing their expression with two other tissues (magnum and duodenum), in which calcium and bicarbonate trans-epithelial transfers are weak and strong respectively. This approach allowed the identification of 33 important genes involved in calcium and bicarbonate ions supplies, a prerequisite needed for the eggshell calcification. This work produced a global and coherent description of the mechanisms supplying the mineral for uterine eggshell formation
Modulation de l'immunité innée moléculaire de l'oeuf by Larbi Bedrani( )

1 edition published in 2013 in French and held by 1 WorldCat member library worldwide

The egg is a balanced source of different nutrients and contains a myriad of antibacterial peptides/proteins that ensure its chemical protection. These molecules are a part of its innate molecular defense and, in addition to the maternal immunoglobulins IgY, contribute to the protection of the forming embryo whose development occurs ex utero. It is well documented that yolk immunoglobulin deposition is induced by the environmental microbiome of the hen but no such evidence is available for antimicrobial peptides/proteins. Therefore the aim of this thesis was to assess whether the hen has the ability to stimulate the innate molecular immunity of the egg white when facing a higher environmental microbial load (commensal or pathogenic). To address these questions, we developed two main experimental approaches; the first assessed the impact of the hen environmental microbial load through the comparison of three groups of hens with different immune status:-Germ free, -Specific pathogen free (SPF), and -conventional. The second approach explored the effect of different types of immune stimulation in hens: non-infectious stimulation (systemic injection of bacterial lipopolysaccharide (LPS)); immune stimulation using attenuated live vaccines (Infectious bronchitis virus vaccine, Salmonella enterica Enteritidis vaccine and a complex of Eimeria vaccine). Our results show that the activity of egg white is increased in response to higher microbial environmental charge, after LPS systemic stimulation or after vaccinating hens with live attenuated viral and bacterial strains. However this response is moderate both in its amplitude and microbial spectrum. Altogether, it appears that hens when subjected to immune stimuli, have the ability to reinforce moderately the antibacterial activity of the egg white as an attempt to anticipate the need of protection of their embryos
Mécanismes régulant l'utilisation périphérique du glucose chez l'oiseau : focus sur le transport de glucose by Edouard Coudert( )

1 edition published in 2016 in French and held by 1 WorldCat member library worldwide

Glucose metabolism in birds is important to control animal growth and meat quality. We studied peripheral glucose utilization in chicken muscle by identifying and characterizing a new glucose transporter in birds, GLUT12. This transporter is expressed in muscles, its expression is regulated in vivo by insulin and it can be enriched in cells plasma membranes following insulin stimulation. In vitro an increase of glucose transport is measured in the same time than GLUT12 translocation. As for GLUT4 in mammals, PI3K pathway is involved in GLUT12 translocation. Expression of muscular GLUTs varies depending on animals' age but also depending on their physiological state and on the metabolic type and/or function on the muscle. All of our results partly explain the atypical glucose metabolism in birds and let us foresee development of new farming strategies in order to answer to increased demand of avian quality products
Optimisation de l'utilisation de phosphore alimentaire chez le porc et le poulet en croissance. by Xavière Rousseau( )

1 edition published in 2013 in French and held by 1 WorldCat member library worldwide

The reduction of dietary phosphorus (P) and the optimisation of its utilisation by the animals represent major challenges for the sustainability of poultry and pig production. The development of new feeding strategies ensuring an efficient utilization of P appears crucial particularly during the finishing period. The present work contributed to redefine the requirement of P of the animals during this phase in conjunction with the other constituents of the feed matrix well-known to significantly impact on the overall utilisation of P (Ca, microbial phytase). Moreover, this work quantified the impact of Ca and microbial phytase on the digestive and metabolic flows of P. On one hand, generated knowledge helps developing mechanistic models simulating the fate of P in the scale of the animal and on the other hand new feeding systems to meet the challenges of sustainability
Effets de phytobiotiques sur les performances de croissance et l'équilibre ou microbiote digestif du poulet de chair by Sarah Guardia( )

1 edition published in 2011 in French and held by 1 WorldCat member library worldwide

The banning of antibiotic growth promoters for livestock feeding led to the development of several alternatives, including phytobiotics. However, their efficiency as growth promoters is inconstant between scientific studies and their mechanisms of action are poorly known. In the present work, the rearing conditions strongly affect the efficiency of two phytobiotics models. They improved the chickens' growth performance when the rearing conditions were unfavorable to the growth. When strongly deteriorated, the combination of phytobiotics showing various biological activities was more efficient. As the phytobiotics used in the present study contains numerous molecules with an in vitro antibacterial activity, the impact of those phytobiotics on chickens' digestive microbiota was studied in vivo. Changes in chickens' digestive microbiota were observed which could partly explain the chickens' growth improvement
