Along the way, he has been recognized as a collaborator of a scientific and biomedical research about “Antibodies from Alpacas as Tools to Study Virus-Host Interactions”. His co-authored scientific research study “Do Differences in Maternal Immunoglobulin G Influence Passive Transfer and Subsequent Cria Growth in Alpacas?” was accepted for publication in the prestigious scientific veterinary journal, Theriogenology.

Arturo and his family donate their free time at the local library and at Cornell University Cooperative Extension 4-H Putnam County doing what he knows the best: creating awareness about the alpaca industry and trying to make the difference in his community.
