A more definitive study and testimonial letter are available on this website in the NEWS and Testimonial Pages that was typed by the well-respected Midwestern United States avian veterinarian, Dr. Peter S. Sakas in his last testimonial letter in 2017 in which he elaborates on the advancement of Avi-Culture-2-PLUS and its evolution in the over 40 years of his use and promotion in his well-known bird health care practice while he was with us, as did its founder, Dr. Theodore LaFeber before him. Both gentlemen have since passed on. May they both rest in peace at The Rainbow Bridge.
