Data format	Raw, Analyzed, Filtered
Parameters for data collection	Field data was obtained from goat production units participating in the performance recording system of the Asociación Mexicana de Criadores de Ganado Caprino de Registro.
Description of data collection	Technical personnel from the Asociación Mexicana de Criadores de Ganado Caprino de Registro regularly visit purebred goat production units in Mexico. During such visits they physically evaluate the animals subjected to registration, they also collect and verify their pedigree and productive information. Animals that comply with the inspection parameters, genealogical and productive information, become part of the national breeding flock of their respective breed. Field data from all participating flocks is then concentrated and managed by the Asociación Mexicana de Criadores de Ganado Caprino de Registro, which then extends the animal registration certificates to individual goat breeders. The Asociación Mexicana de Criadores de Ganado Caprino de Registro provides the national database to Universidad Autónoma Chapingo for genetic evaluation purposes, and on a yearly basis, breeding values for growth traits are estimated and published.
