Between positive impact and negative consequences, the complex effects of inbreeing on the reproduction of the rainbow trout

Through the genetic improvement of the rainbow trout, the efficiency of trout production over the last thirty years has increased notably. But this selection has also contributed to an increase in inbreeding, menacing genetic progress on the long term and the adaptation of populations to a changing environment. That is why scientists from the GABI unit sought to evaluate the effects of inbreeding on the reproductive performances of the rainbow trout.

FROGS : a frog attacking fungi

Microbial ecosystems (intestinal, food, soil microbiota, ....) are continuously being recognized for their major role in many fields: amongst them, fungi frequently enter scientific debates. The new version of the FROGS software allows the precise identification of fungal communities present in the microbiota in addition to the bacterial communities identified by the previous version.

From the cow to poplar tree, from bees to wheat, how does genomic selection work?

For 10 years, in dairy cattle, "classical" selection has been put aside for genomic selection. This evolution has allowed more rapid progress and a considerable reduction in the cost of selection. Since then, it has been applied to an ever increasing number of animal and plant species and has spiked interest in many others.

A sea of microplastic troubles: long-term ingestion harms growth and reproduction in fish

INRAE, Ifremer and the Universities of Bordeaux (France) and Orebrö (Sweden) have been studying the toll taken by lifelong exposure to toxic microplastics on key biological functions in fish. Two species of fish, one freshwater and the other marine, were exposed for a period of four months to different microplastics, some of which were coated with organic pollutants (spiked), while others were left unmodified (virgin). The team’s findings appear in the 5 August 2021 issue of the Journal of Hazardous Materials and reveal harmful impacts on both growth and reproduction for this extended experimental exposure period. How seriously the two core functions were affected depended on a number of variables including polymer type, presence or absence of organic pollutants, and length of exposure.

Relation between intestinal microbiota composition and influenza A virus vaccination response in pigs

A study led by the Genetics, Microbiota, Health team of GABI shows that in pigs, a relation exists between the intestinal microbiota composition and the immune response to a vaccine against the influenza A virus (IAV) in pigs. The intestinal microbiota before vaccination has both high and low responders to vaccination and contains predictive information about these levels of response. A higher level of some bacteria genera was found to be associated with a better immune response to the vaccine.

H2020 GEroNIMO : designing tomorrow's breeding in monogastrics

Within the framework of the European Horizon 2020 program, teams from the Genetics Physiology and Farming Systems Unit (GenPhySE) of the Occitanie-Toulouse INRAE research center and GABI have been awarded 7 million euros over five years for the GEroNIMO project (Genome and Epigenome eNabled breedIng in MOnogastrics). This Europe-wide multi-actor participative project began in June 2021. It will promote studies on ways to improve genetic selection in animal breeding and to conserve genetic and epigenetic diversity, in order to provide new knowledge and perspectives to stakeholders, while taking into account current issues associated with sustainable development.

Studying the adaptation of bovine to climate change

In the current context of climate change, one of the challenges in breeding is the adaptation of animals to heat. Cattle are particularly sensitive to heat stress which affects their welfare and their performances. The CAICalor (financed by Apis-Gene) and Rumigen (H2020) projects are aimed at studying the adaptation of cattle to climate change at both phenotypic and genetic levels.

Galactinnov : creation of an international research network for high quality and sustainable dairy production

The GALACTINNOV International Research Network (Réseau de recherche à l’international or 2RI) agreement was signed on Friday 7 May, during an online meeting hosted by Marie-Josée Hébert, Vice-Rector for Research, Discovery, Creation and Innovation at the University of Montreal, and Philippe Mauguin, Chair and CEO of INRAE. The launch event was attended by representatives and scientists from the eight partners of the Franco-Canadian network: INRAE, Institut Agro, the National Veterinary School of Toulouse (ENVT), the University of Tours in France, and the University of Montreal, Université Laval, the University of Sherbrooke and McGill University in Quebec, Canada. Their common objective is to structure their collaboration based on high-quality dairy production while respecting the environment as well as animal health and welfare.

Assessment of trade-offs between feed efficiency, growth-related traits, and immune activity in experimental lines of layer chickens

All organisms are inherently constrained by the resources that are available to them, and must therefore allocate these limited resources among competing functions. This idea is central to the biological concept of trade-offs, which represent the costs incurred when a change in one trait results in an unfavorable change in another. Although the environment of domestic animals is more controlled than that of wild species, especially for food resources, the intensive selection for production and feed efficiency may have unintentionally triggered negative effects on other fundamental functions, such as the immune response, which may lead to detrimental effects on animal health and welfare.

The metabolic secrets of horse-athlete endurance

The intestinal microbiota and energy centers of the blood cells of horses communicate to ensure an unfailing endurance! A dialogue based on fatty acid production allows the animal to adapt its metabolism to delay fatigue, hypoglycemia and reduce inflammation. These are the conclusions of a study led by INRAE in partnership with the National Veterinary School at Alfort and the University of Evry. These results, published in Frontiers in Molecular Biosciences lead the way to custom-made diets for endurance race horses, to guarantee their performances, welfare and health.

Resilience of the intestinal microbiota in stressed equine athletes

Elite horse athletes that live in individual boxes undergo long-term physical and mental stress that compromises the welfare of these animals altering their intestinal microbiota. In a studied published in Scientific Reports, scientists from INRAE laboratories including Animal Genetics and Integrative Biology - GABI evaluated whether a temporary period at pasture with other animals could improve animal welfare and, in return, favorably affect the intestinal microbiota composition.
