Bien-être animal : quelles relations entre les critères physiologiques et comportementaux d'adaptation [Animal welfare: what are the relationships between physiological and behavioural measures of adaptation ?] Animal Physiology
Richard, S.; Aupérin, B.; Bolhuis, J.E.; Geverink, N.A.; Jones, B.C.; Lepage, O.; Mignon-Grasteau, S.; Mormède, P.; Prunet, P.; Beaumont, C..
La multiplicité des critères susceptibles d'être utilisés pour évaluer l'adaptation comportementale d'un animal à son environnement a motivé l'étude des relations entre réponses physiologiques et comportementales, dans l'espoir que l'identification de telles relations puisse simplifier l'évaluation du bien-être animal. La comparaison d'animaux placés dans des environnements différents et la comparaison d'animaux aux génotypes extrêmes suggèrent l'existence de relations entre certaines réponses physiologiques et comportementales. La possibilité de catégoriser certains animaux selon leur stratégie de réponse adaptative, caractérisée par des associations répétables entre réponses comportementales et physiologiques, conforte cette hypothèse. Cependant, les...

Bien-être chez les poissons d'élevage [Recent development of aquaculture rose interest for fish welfare in aquaculture farms] Animal Physiology
Prunet, P.; Aupérin, B..
Le récent développement de l'aquaculture a conduit à s'intéresser au bien-être des poissons en élevage. A la question du ressenti de la douleur chez le poisson, il est le plus souvent admis que ces animaux sont capables de la percevoir mais pas nécessairement d'en avoir la même conscience au niveau cérébral que chez l'homme. Exposés à des situations de stress, les poissons présentent globalement les mêmes stratégies physiologiques et comportementales que les vertébrés terrestres. C'est à partir de ces informations qu'a été abordée la caractérisation du bien-être chez les poissons en favorisant une approche multiparamétrique. Les activités associées à l’élevage des poissons constituent autant de facteurs susceptibles de modifier leur niveau de bien-être....

Genetics of adaptation and domestication in livestock Animal Physiology
Mignon-Grasteau, S.; Boissy, A.; Bouix, J.; Faure, J.M.; Fisher, A.D.; Hinch, G.N.; Jensen, P.; Le Neindre, P.; Mormede, P.; Prunet, P.; Vandeputte, M.; Beaumont, C..
In this review, we assess the current state of knowledge on domestication of the major livestock species. We present first some historical background on location and dates of domestication of livestock. The characteristics that favoured domestication are described, especially gregariousness, precocity of young and diet. We then describe the genetic processes involved during domestication, i.e. uncontrolled processes such as inbreeding and genetic drift, partially controlled processes such as relaxation of natural selection and natural selection in captivity and controlled processes such as active selection. Details are also given on how the resource allocation theory explains changes occurring during domestication. The methods used to assess the extent to...

Hydration of rainbow trout oocyte during meiotic maturation and in vitro regulation by 17,20b-dihydroxy-4-pregnen-3-one and cortisol Animal Physiology
Milla, S.; Jalabert, B.; Rime, H.; Prunet, P.; Bobe, J..
While oocytes of many teleost fish, especially marine species, are subjected to a hydration process occurring during meiotic maturation and leading to an important volume increase, no noticeable hydration of the preovulatory oocyte was ever reported in rainbow trout (Oncorhynchus mykiss). In the present study, oocyte water content and dry weight were monitored using consecutive samples taken in vivo from the same female rainbow trout, from 4-5 days prior to ovulation up to 7 days post-ovulation. In addition, yolk protein electrophoretic patterns were compared between oocytes sampled prior to germinal vesicle breakdown (GVBD) and unfertilized eggs. Furthermore, the effect of the maturation-inducing steroid (17,20b- dihydroxy-4-pregnen-3-one, 17,20b-P),...

Impacts zootechnique et socio-économique potentiels d'une éventuelle utilisation de la rtGH en salmoniculture Inra
Maisse, G.; Bonnieux, F.; Fauconneau, B.; Faure, A.; Gloaguen, Y.; Le Bail, P.Y.; Prunet, P.; Rainelli, P..
Les salmonidés (Truite et Saumon) sont la principale production piscicole de l’Europe de l’ouest. Les biotechnologies animales intéressant la salmoniculture relèvent de trois domaines : les manipulations génétiques (la triploïdie pour la production de poissons stériles), le transfert de gène (pour produire des poissons résistants aux maladies infectieuses) et les peptides recombinants (vaccins recombinants contre les maladies virales, l’hormone de croissance recombinante de truite -rtGH-).La rtGH a deux effets biologiques principaux : une stimulation de la croissance, en particulier en eau froide, et une amélioration de l’adaptation des juvéniles à l’eau de mer. Un traitement chronique avec la rtGH peut accroître de manière substantielle la production des...

Induction of rabbit casein synthesis in organ culture by tilapia prolactin and growth hormone Animal Physiology
Houdebine, L.M.; Walker Farmer, S.; Prunet, P..
Highly purified tilapia (Sarotherodon mossambicus) prolactin and growth hormone added to culture medium of rabbit mammary gland explants specifically stimulated casein synthesis. The synthesized casein was quantified by an immunoprecipitation and further identified by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. In addition, the lactogenic activity of the fish hormones was determined by measuring the accumulation of beta-casein mRNA using a 3H-labeled DNA complementary to the beta-casein mRNA as a probe in a molecular hybridization. Moreover, tilapia prolactin was able to compete slightly with [125I]prolactin for the binding to rabbit mammary gland prolactin receptor. The lactogenic activities of the tilapia prolactin and...

Quantitative genetic variation for post-stress cortisol and swimming performance in growth-selected and control populations of European sea bass (Dicentrarchus labrax) ArchiMer
Vandeputte, Marc; Porte, J. D.; Auperin, B.; Dupont-nivet, M.; Vergnet, Alain; Valotaire, C.; Claireaux, Guy; Prunet, P.; Chatain, Beatrice.
Sea bass is a major species in Mediterranean aquaculture, and is now being subject to selective breeding programs for faster growth. In terrestrial species, it was demonstrated that fast growth may be linked to a correlated degradation of fitness traits. In this experiment, we evaluated 600 young sea bass from a factorial mating of 76 sires and 13 dams. The sires were from four genetic groups, wild (W), domesticated (D), and selected for growth (2 groups, M and P). The 600 offspring were submitted to two acute confinement stress challenges at 6 weeks intervals, and plasma cortisol at one hour post stress was measured. The same fish were also submitted to two swimming challenges at a 5 days interval, where the maximum sustained swimming speed (Umax) of each...

Recent advances in EST sequencing in Crassostrea gigas: towards the sequencing of the Pacific oyster genome ArchiMer
Boudry, Pierre; Huvet, Arnaud; Lapegue, Sylvie; Sauvage, Christopher; Tanguy, A.; Moraga, D.; Goostrey, A.; Prunet, P.; Boulo, Viviane; Gueguen, Y.; Moal, Jeanne; Fleury, Elodie; Samain, Jean-francois; Mathieu, M.; Favrel, P..
Rationale for EST and genome sequencing of the Pacific oyster: • its membership of the Lophotrochozoa, an little studied branch of the Eukaryotes, • its worldwide aquacultural importance (4.2 million metric tons, worth 3.5 billion US dollars), • its high fecundity, with concomitantly high DNA polymorphism, • its use as a biosensor of coastal pollution. In 2004, an international community of biologists, the Oyster Genome Consortium (OGC) led by D. Hedgecock (University of Southern California) and uniting 70 participants from 10 countries, first presented the Pacific oyster Crassostrea gigas as a genome-sequencing candidate to Joint Genome Institute (JGI, USA) (Hedgecock et al., 2005). Besides this project (that remains to be accepted), several EST...

Sexual differences in salmon gonadotropin Animal Physiology
Breton, B.; Prunet, P.; Reinaud, P..
Salmon (Oncorhynchus tschawytscha) GTH's were purified from a mixture of pituitaries of both sexes or from separate male and female glands. Some of their biochemical, immunological and biological properties have been compared. These hormones differed essentially in amino acid composition, especially lysine, histidine and half cystine residues, and by the presence of alpha-amino (or alpha-aminoiso) butyric acid in male and GTH II preparations. The same differences were found between GTH I-II and GTH male-female. Observed biochemical differences were sex-linked ; they did not influence immunological and qualitative biological effects, but could determine the affinity of the GTH of each sex or its specific receptors.

Stimulation of milk synthesis in the rabbit by fish pituitary extract Animal Physiology
Prunet, P.; Houdebine, M.; Delouis, C.; Breton, B..
The lactogenic properties of extracts of the pituitary glands of salmon and trout were evaluated by using the organ culture technique with rabbit mammary explants. Crude extracts and fractions obtained after chromatography on Ultrogel and selected for their capacity to compete with ovine prolactin in a rabbit mammary gland radioreceptor assay were added to the culture medium. The criteria of lactogenesis were lactose synthetase activity, casein synthesis, measurements of the concentration of casein messenger RNA and the histology of mammary glands. All these tests led to the conclusion that salmon and trout pituitary glands contain a prolactin-like principle capable of initiating milk synthesis in the rabbit mammary cell.

Trout gill cells in primary culture on solid and permeable support Animal Physiology
Leguen, I.; Cauty, C.; Odjo, N.; Corlu, A.; Prunet, P..
Trout gill cells in primary culture on solid and permeable supports were compared. Cultures were carried out by directly seeding cells on each support after gill dissociation. Most of the cell types present in culture were similar, regardless of culture support (pavement cells, mucous cells (3-4%), but no mitochondria-rich cells). However, insertion of mucous cells in cultured epithelium on permeable support presented a morphology more similar to gills in situ. Gene expression of ion transporters and hormonal receptors indicated similar mRNA levels in both systems. Cortisol inhibited cell proliferation on both supports and maintained or increased the total cell number on solid and permeable membranes, respectively. This inhibition of mitosis associated...
