This document is the user's manual of DynaMod, which is a simple tool for demographic projection of tropical livestock populations. DynMod is intended to researchers, developers, engineers and technicians of national services, or students dealing with demography of tropical livestock. DynaMod represents animal populations that can be divided in juvenile, sub-adult, and adult age groups and that have a reproduction distributed all over the year. The handbook is composed of three chapters. Chapter one discusses the general principles of DynMod. Chapter two describes its interface, and chapter three presents some numerical examples of simulations. The manual ends with an appendix that details the concept of hazard rates and the equations used in the demographic model.
