The PACOMARCA ranch possesses a specially selected experimental population of approximately 600 pure-black alpacas which are the subject of a genetic evaluation program and a unique inheritability study. This is the country's largest population of pure-black alpacas at a single ranch.
The Yanapaco program makes direct purchases of pure-black alpaca fiber from interested producers at a preferential price. Furthermore, an exchange scheme has been started for some selected producers with black male alpacas.
Finally, a new category has been introduced in The Inca's Quintal competition, where prizes are awarded for the best pure-black fleeces, so as to encourage the raising of black animals.
