By virtue of the alpaca database held at PACOMARCA, the world's widest and most complete, and the collaboration with the Complutense University of Madrid, many scientific papers have been written and published in the most important international indexed journals.
PACOMARCA also frequently presents non-scientific information on its genetic-improvement program in different international and national publications as well as at veterinary conferences, meetings of groups brought together by a common interest in alpaca, specialized events, university-level lectures and so on.
