About

Jennifer Halleran is an assistant professor at North Carolina State University College of Veterinary Medicine. She is originally from New Jersey and holds a B.S. in Animal Science and Microbiology from the University of Rhode Island. She earned her Doctor of Veterinary Medicine (DVM) degree from Colorado State University in 2014. Following her veterinary degree, she completed a ruminant health internship at North Carolina State University and a large animal internal medicine residency at Oklahoma State University. She became a diplomate of the American College of Veterinary Internal Medicine Large Animal in 2019. Subsequently, she completed a PhD in Infectious Disease at NC State University. Her research focuses on enteric bacteria and their antimicrobial resistance profiles in large animals, contributing to the understanding of infectious diseases and antimicrobial resistance in veterinary medicine.

• Short communication: Apparent efficiency of colostral immunoglobulin G absorption in Holstein heifers

  Journal of Dairy Science · 2017-02-09 · 29 citations

  articleOpen access1st author

  Adequate absorption of bovine colostrum correlates with improved neonatal health. The apparent efficiency of absorption (AEA) of immunoglobulins can be measured using a mathematical equation based on serum and colostral IgG concentration levels, as well as calf body weight and the volume of colostrum being fed. Although commonly measured in research projects, little information is available on the normal AEA across a large group of healthy calves on multiple farms. The purpose of this study was…

• Effects of danofloxacin dosing regimen on gastrointestinal pharmacokinetics and fecal microbiome in steers

  Scientific Reports · 2021 · 8 citations

  Fluoroquinolones are a class of antimicrobial commonly used in human medicine, and deemed critical by the World Health Organization. Nonetheless, two formulations are approved for the treatment of respiratory disease in beef cattle. The objective of this study was to determine the gastrointestinal pharmacokinetics and impact on enteric bacteria of cattle when receiving one of the two dosing regimens (high: 40 mg/kg SC once or low: 20 mg/kg IM q48hr) of danofloxacin, a commonly utilized synthetic…

• Comparison of the Intestinal Pharmacokinetics of Two Different Florfenicol Dosing Regimens and Its Impact on the Prevalence and Phenotypic Resistance of E. coli and Enterococcus over Time

  Microorganisms · 2021 · 6 citations

  In order to mitigate the food animal sector's role in the growing threat of antimicrobial resistance (AMR), the World Health Organization (WHO) suggests the use of lower tier antimicrobials, such as florfenicol. Florfenicol has two dosing schemes used to treat primarily bovine respiratory disease. In this study, the objective was to characterize the plasma and gastrointestinal pharmacokinetics of each dosing regimen and assess the effect of these dosing regimens on the prevalence of resistant in…

• Flunixin meglumine tissue residues after intravenous administration in goats

  Frontiers in Veterinary Science · 2024-01-09 · 5 citations

  articleOpen access

  Background: Flunixin is commonly used in goats in an extra-label manner, indicating a significant need to determine withdrawal intervals for edible tissues. Objective: The objectives of the present study were to investigate the depletion of flunixin meglumine in various goat tissues, including the liver, kidney, fat, and muscle. Methods: Twenty Boer goats were enrolled and administered an intravenous dose (2.2 mg/kg) of flunixin meglumine. Five animals were randomly euthanized at 24, 48, 72, or…

• Update on withdrawal intervals following extralabel use of procaine penicillin G in cattle and swine

  Journal of the American Veterinary Medical Association · 2021-11-18 · 5 citations

  article1st authorCorresponding

  IntroductionExtralabel drug use (ELDU) is defined as the use of an FDA-approved medication in a manner that differs from what is provided on the label of the medication.1 Administration of the medication to a different species or at a different dose, volume, route, duration, indication, or frequency than indicated on the label is considered ELDU. Extralabel drug use also requires an extended withdrawal period to avoid violative residues, and practitioners can get advice on withdrawal intervals (…
