• [hal-03481066] ƒ‐statistics estimation and admixture graph construction with Pool‐Seq or allele count data using the R package poolfstat - samedi 15 janvier 2022

  By capturing various patterns of the structuring of genetic variation across populations, f -statistics have proved highly effective for the inference of demographic history. Such statistics are defined as covariance of SNP allele frequency differences among sets of populations without requiring haplotype information and are hence particularly relevant for the analysis of pooled sequencing (Pool-Seq) data. We here propose a reinterpretation of the F (and D) parameters in terms of probability of...

• [hal-03326793] From National Biosecurity Measures to Territorial ASF Preparedness: The Case of Free-Range Pig Farming in Corsica, France - vendredi 14 janvier 2022

  In response to African swine fever (ASF) outbreaks in wild boars in Belgium in 2018, the French authorities issued national biosecurity measures for all pig farms, regardless of their geographical and socio-technical scale. Considering the Corsican pig farmers' demonstrations against these measures (for geographical, cultural, and economic reasons), this article questions the suitability of standardized top-down national measures that potentially endanger traditional breeding systems, which are...

• [hal-03265753] Action collective et gestion sanitaire des élevages porcins en Corse - vendredi 14 janvier 2022

  La nouvelle gouvernance du sanitaire en France demande aux organisations de producteurs de prendre davantage part à la concertation et la décision concernant la santé animale. Or, la filière porcine en Corse s’est récemment organisée à travers des organisations visant l’intégration économique qui ne représentent pas l’ensemble du secteur et qui restent fragiles. L’article met au jour d’autres formes d’action collective, peu visibles a priori, en lien avec deux dispositifs...

• [hal-03518631] Unmanned aerial vehicle for the assessment of woody and herbaceous phytomass in Sahelian savanna - jeudi 13 janvier 2022

  The phytomass of herbaceous and woody plants is the main source of feed for pastoral livestock in the Sahelian savanna. The assessment of the available feedstock plays a key role in national livestock policies and generally requires many field measurements of both herbaceous and woody plants. In this study, we tested the possibility of using a red-green-blue (RGB) unmanned aerial vehicle (UAV) to evaluate the phytomass of both woody and herbaceous species. We thus mapped 38 one hectare plots...

• [hal-03410902] Intake and digestibility of meat ewes belonging to two contrasting feed efficiency genetic lines, during their two first production cycles - mercredi 12 janvier 2022

  Feed is the largest cost in animal production, therefore improving feed efficiency (FE) is one of the main priorities when redesigning farming systems. The objective of this work was to evaluate the effects of a divergent genetic selection for FE in Romane rams [i.e. efficient (RFI-) or inefficient (RFI+)] on the feed intake and nutrient digestibility of their daughters (ewes), reared in different conditions. Different to their sires, which were fed high concentrate-diets, the ewes were fed ad...
