Matthieu Lesnoff, Renaud Lancelot, Charles-Henri Moulin, Samir Messad, Xavier Juanes, Christian Sahut Calculation of Demographic Parameters in Tropical Livestock Herds

Annotation

Having indicators to assess the effect of zootechnical, sanitary, economic or political intervention or the impact of environmental risks makes it possible to draw up strategies for improving domestic animal populations. This handbook is a compilation of the main concepts relating to the definition and calculation of demographic rates for largely non-intensive tropical animal farms. It is intended to be educational, and should help students, technicians, engineers, researchers and development staff to understand the definitions and formulas encountered in the literature more clearly and make them more self-sufficient in terms of analyses.
