Madagascar is a country with a breeding vocation. However, bovidae statements are unsatisfactory, as pedigree information and performance data are not present. This study is carried out at the FOFIFA Kianjasoa station and its surroundings using the LASER method: Ruminant Livestock Monitoring Assistance Software by the Department of Veterinary and Piscicultural Zootechnical Research (DRZVP) in the ECLIPSE project : Emerging Crop Livestock Production System adapted to a changing Environment reinforced by the IAEA: International Atomic Energy Agency providing boluses in electronic chip form. During the study, a total of 440 heads of cattle are monitored by monthly weighing the animals whose breeds are Renitelo, Frisian and Zebu Malagasy. This study is far from exhaustive, so a perspective is considered on the use of the electronic bolus to control the phenomenon of "Dahalo" in Madagacar. Is it possible to manage the insecurity that reigns in the field of breeding from this method?
