Description: Effect of Formic Acid Treatment on Colostrum Quality, and on Absorption and Function of Immunoglobulins: A Randomized Controlled Trial in Holstein Dairy Calves Billy I. Smith, Sarah V. Cady, Helen Aceto. Department of Clinical Studies – New Bolton Center, University of Pennsylvania, School of Veterinary Medicine, Kennett Square, PA. Colostrum is crucial to calf health but must be of good quality, characterized by high immunoglobulin content and low pathogen load. Many techniques to decrease pathogens can damage immunoglobulins, potentially reducing both their absorption and function. Objectives of this randomized controlled trial were to determine the effect of formic acid treatment on colostral bacterial and immunoglobulin levels before feeding, and serum immunoglobulin levels and neutralizing capabilities after feeding.
