Formic Acid Acidified Colostrum Trial

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.

福尔马酸处理对初乳质量及其免疫球蛋白吸收与功能的影响：一项针对荷斯坦奶牛犊的随机对照试验，作者：比利·I·史密斯，莎拉·V·凯迪，海伦·阿切托。新布伦托中心临床研究部，宾夕法尼亚大学兽医学院，肯尼特广场，宾夕法尼亚州。初乳对于犊牛健康至关重要，但其质量必须上乘，其特征为高免疫球蛋白含量和低病原体负荷。众多降低病原体的技术可能损害免疫球蛋白，从而可能降低其吸收和功能。本随机对照试验旨在确定福尔马酸处理对喂食前初乳中细菌和免疫球蛋白水平，以及喂食后血清免疫球蛋白水平和中和能力的影响。
