The kick-off of the H2020 SCALA-MEDI project included 17 European partners for the launching of this project whose objective is the improvement of the sustainability and the quality of ovine and poultry production via the development of the adaptation potential of local breeds in the MEDIterranean area.
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.
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.
Evaluating health status, behavior and welfare of dairy cows at pasture is one of the objectives of this experiment that began in January 2020 on the INRAE Pin Farm in Normandy. Web-agri and INRAE have joined forces to provide a series of videos presenting the Tripl'XL programme.
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.

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.
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.
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 GiBBS team just published a "core concept" Mathematics article on big data, data sciences, and algorithms in the journal Frontiers in Young Minds. A very enriching experience with young reviewers!
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.
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.
The composition in minerals of cow's milk plays an important role in its nutritional value and its cheese-making abilities. By combining high-throughput phenotyping with middle infrared spectrometry (MIR), large-scale genotyping, association and annotation analyses, 50 regions of the genome were detected that affect the main mineral concentrations, identifying the genes implicated and candidate genetic variants (usually involved in regulation). The genes SLC37A1 and ANKH explain the most significant QTL.
Due to the major challenges facing our societies, expectations of research are growing. To respond through real innovation to the industry's and society's problems, the intensifiction of interactions between public resarch with companies is a key. By placing innovation as one of the pilars in its strategy for the next 10 years , at the beginning of 2021, INRAE has launched a new type of partnership with social-economic actors: the Associated Partnership Laboratory. Thus, on the basis of a common roadmap for 5 years, the partnership will allow INRAE and Excilone to share their material and human resources around a co-conceived research and technological programme in the field of microgenomics. This is a new type of partnership for INRAE that is both flexible and adaptable whose objective is to accelerate the development of new innovations.
Her PhD dissertation is entitled, "Study of the impact of host genetics and gut microbiota composition on Salmonella Enteritidis carriage in mice and chickens".
In meadows, we can sometimes see sheep and goats with four horns instead of two. Some breeds, like the Manx Loaghtan from the Isle of Man, are famous for their unusual headgear. A team of researchers from INRAE, the University of Geneva, the Polytechnic School of Lausanne, the French National Union of Cooperatives for Animal Insemination (ALLICE), as well as from several museums and breeding associations, has been investigating the genetic causes of this curious morphological phenomenon. Published in the journal Molecular Biology and Evolution on 16 February 2021, their results show that all the polycerate animals studied carried a mutation in the same gene: HOXD1.
