Characteristics of failure of passive transfer at the herd level using the serum immunoglobulin G concentration as an indicator on dairy farms in eastern Hokkaido, Japan.
The objectives of this study were to conduct a survey of failure-of-passive-transfer (FPT) in eastern Hokkaido Japan, to evaluate the association between herd-level FPT and death and culling or treatment, and to test the effectiveness of monitoring using herd-level FPT. A total of 4,411 Holstein and Holstein-Wagyu crossbreds calves born from Holstein dams during the year beginning April 2, 2019 on 39 dairy farms were included in the study to investigate death-and-culling and the treatment rate during the first month of life, as well as rearing management up to 3 weeks of age. A subset of Holsteins (n=381) was included in the study for passive transfer and farms were diagnosed as having FPT if more than 20% of newborn calves had serum IgG levels below 10 g/L at the herd level. The prevalence of FPT (

JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
