Livtools: Tools for estimating and simulating livestock productions in tropical extensive farming systems
Home
This Website provides methodological materials for implementing quantitative analyses in tropical livestock farming systems, with particular focuses on herd performances estimation and modelling, and near infrared spectroscopy (NIRS) data analyses.

- mmage A R package for sex-and-age population matrix models
- Dynmod A simple spreadsheet interface for demographic projections of tropical ruminant livestock populations
Herd performances parameters
- Laser2 An animal-based monitoring survey method and information system (demography, milk, live weight, health, artificial insemination, etc.)
- laser2demog A R package for discrete-time calculation of livestock demographic parameters using Laser2 data
- 12mo A 12-month retrospective survey method and information system (demography)
