Abstract

Recently developed genomic tools, like SNP-genotyping and whole genome sequencing, and their analysis, offer great opportunities for the conservation and utilisation of animal genetic diversity, both among and within breeds. These genomic tools can be used to detect potentially valuable rare alleles and haplotypes. They are important parts of the genetic diversity we need to conserve now for possible utilisation in the future. This book describes the use of genomic technology to define breeds, to measure diversity and to assess important features in the history of breeds affecting the present genetic diversity. The management of genetic diversity with genomic tools is outlined both in vivo: small populations of rare breeds or large populations with small effective population sizes and in vitro: genebanks. Special attention is given to the genomic management of populations of animals with high incidences of genetic defects. This book is intended for MSc and PhD students, scientists working with small populations in animal breeding and in conservation programmes for rare breeds.

Abstract

Au Cameroun et au Nigeria, les taurins - petits bovins sans bosse - sont très minoritaires par rapport aux zébus. Ils présentent pourtant l'avantage d'être mieux adaptés au milieu : résistants à la mouche tsé-tsé, ils pourraient aider à la mise en valeur des zones infestées et ils apparaissent dans certaines régions humides comme les seuls bovins aptes à favoriser l'inter-pénétration de l'agriculture et de l'élevage. Mais la relance de ces élevages, tant au Cameroun qu'au Nigeria, a toujours posé problème : l'imbrication du social, du religieux et du politique dont ils sont porteurs en fait des élevages archaïques, difficilement récupérables par les sociétés villageoises poraines, contemet donc en voie d'extinction. La « laïcisation » du taurin et son introduction dans une économie de marché restent à faire. Cet ouvrage réunit des géographes, ethnologues, anthropologues, vétérinaires-zootechniciens. Il contribue à une meilleure compréhension du fonctionnement social des élevages, et apporte une description précise de ces animaux et de leur portement com: deux préalables nécessaires à l'identification de « nouveaux types d'éleveurs » et à la mise en oeuvre de nouvelles pratiques zootechniques et sociales. In Cameroon and Nigeria, taurines — small humpless cattle —form a minority in comparison with zebu. Nevertheless, they are better suited to the environment. Taurines (Bos taurus) are resistant to tsetse fly and could help in the farming of infested zones and are the only cattle that can be reared in combination with arable farming in certain wet régions. However, relaunching taurine rearing in both Cameroon and Nigeria has always been a problem. The overlapping of the social, religious and political spheres in which they are involved means that rearing is archaic, difficult to adopt by contemporary village societies and is therefore disappearing. The taurine remains to be rendered 'seculaf and incorporated in a market economy. Geographers, ethnologists,…
