Join us for our monthly virtual presentation facilitated by experts in their field.
November 21, 2025
12:00 - 1:00 pm (Eastern)
TOPIC: Transfer and persistence of colostrum-derived specific antibodies to the respiratory and enteric mucosa in calves
Presenter: Dr. Manuel Chamarro
This program has been submitted, but not yet approved, for one (1) hour of continuing education credit in jurisdictions that recognize RACE approval.
This seminar will review the transfer of IgG-1 from colostrum and its role in preventing infection in calves. The role of this antibody specific to common respiratory and enteric viruses into the mucosa after colostrum intake and its role in protection against clinical disease, as well as on vaccination efficacy, in neonatal calves will be discussed.
Dr. Chamorro received his DVM from the National University of Colombia in 2003, then joined a private dairy practice in Bogota, Colombia. In 2007, Dr. Chamorro moved to the United States for an internship in Food Animal Medicine and Surgery at Kansas State University. Following the internship, he was a Food Animal Internal Medicine resident at Auburn University and achieved board certification by the American College of Veterinary Internal Medicine. He stayed at Auburn as a Clinical Instructor of food animal medicine and surgery and completed a PhD program in immune responses to respiratory viruses in cattle during that time.
Dr. Chamorro was a Clinical Assistant Professor of Livestock Medicine and Field Service at Kansas State University for 4 years before returning to the faculty at Auburn in 2019.
Dr. Chamorro’s primary clinical interests include medical and surgical conditions affecting food animals especially cattle. Dr. Chamorro’s research interests are concentrated on respiratory viruses of cattle with specific emphasis in BVDV and in the effect of colostrum-derived immunity on clinical protection and immune response to vaccination in calves.
Other area of interest for Dr. Chamorro is the use of bovine colostrum or colostrum replacers as an alternative to reduce disease and the use of antibiotics in calves.
Our monthly presentations are one hour long and cover a variety of topics we believe you will find interesting and educational. Also, all sessions are recorded and made available in our Resource Library for viewing on-demand by our members at a later time.
