Over the past twenty four years or so, PACOMARCA has been conducting Peru's most sophisticated and comprehensive program on the genetic improvement of alpacas.  The PACOMARCA Scientific Station maintains approximately two thousand five hundred selected alpacas of different types and colors. It holds the world's widest and most complete database on alpaca, which is managed through a specially designed program called PacoPro, whose current version is the 5.7.

The genetic improvement program is carried out with advisory services provided by the animal husbandry department of the Complutense University of Madrid, led by Dr Juan Pablo Gutiérrez García, an international expert on the topic.  As a result of this collaboration, more than twenty scientific papers have been published in some of the world's most prestigious indexed scientific journals.

The PACOMARCA genetic program selects animals on the basis of quantitative genetics in which the BLUP (best linear unbiased predictions) methodology is applied.  At the present time, 81% of the animals at PACOMARCA have desirable genetic ratings.  Furthermore, PACOMARCA has become involved in genomics and selection assisted through the use of markers.

Additionally, PACOMARCA has signed a collaboration agreement with the agrarian University of la Molina, Peru's most prestigious university in the areas of veterinary and animal sciences, and the Alianza EPS Rural Company, the largest alpaca company in the world with a population of thirty-six thousand animals.
