Sung Woo Kim

About

Sung Woo Kim, Ph.D., is the William Neal Reynolds Distinguished Professor and University Faculty Scholar in the Department of Animal Science at North Carolina State University. He earned his Ph.D. and postdoctoral training in Animal Nutrition at the University of Illinois at Urbana-Champaign under the mentorship of Dr. Robert A Easter, and holds M.S. and B.S. degrees in Animal Nutrition and Animal Science from Seoul National University, Korea. Dr. Kim has held academic positions at Texas Tech University and North Carolina State University, where he has been a full professor since 2012. His research expertise lies in animal nutrition, physiology, and biotechnology, with a focus on non-ruminant nutrition, gut health, and the nutritional regulation of animal growth and development. He has contributed significantly to the understanding of amino acid nutrition, oxidative stress, and the modulation of gut microbiota in pigs, as evidenced by his leadership roles in numerous scientific symposia and editorial positions in leading journals in animal science and nutrition. Dr. Kim's work has been recognized with multiple prestigious awards, including the Vernon R. Young International Award for Amino Acid Research and the American Feed Industry Association Award in Non-Ruminant Nutrition Research. He is a fellow of the American Association for the Advancement of Science and serves on advisory groups and editorial boards internationally, reflecting his global impact on animal nutrition…

• Intestinal Health of Pigs Upon Weaning: Challenges and Nutritional Intervention

  Frontiers in Veterinary Science · 2021 · 150 citations

  Senior authorCorresponding

  The primary goal of nursery pig management is making a smooth weaning transition to minimize weaning associated depressed growth and diseases. Weaning causes morphological and functional changes of the small intestine of pigs, where most of the nutrients are being digested and absorbed. While various stressors induce post-weaning growth depression, the abrupt change from milk to solid feed is one of the most apparent challenges to pigs. Feeding functional feed additives may be viable solutions t…

• Intestinal microbiota and its interaction to intestinal health in nursery pigs

  Animal nutrition · 2021 · 129 citations

  Senior authorCorresponding

  The intestinal microbiota has gained increased attention from researchers within the swine industry due to its role in promoting intestinal maturation, immune system modulation, and consequently the enhancement of the health and growth performance of the host. This review aimed to provide updated scientific information on the interaction among intestinal microbiota, dietary components, and intestinal health of pigs. The small intestine is a key site to evaluate the interaction of the microbiota,…

• Mycotoxin Occurrence, Toxicity, and Detoxifying Agents in Pig Production with an Emphasis on Deoxynivalenol

  Toxins · 2021 · 115 citations

  Senior authorCorresponding

  toxins, such as deoxynivalenol and fumonisins, because of their elevated frequency at a global scale and high occurrence in corn, which is the main feedstuff in pig diets. The toxic effects of aflatoxins, deoxynivalenol, and fumonisins include immune modulation, disruption of intestinal barrier function, and cytotoxicity leading to cell death, which all result in impaired pig performance. Feed additives, such as mycotoxin-detoxifying agents, that are currently available often combine organic and…

• Gruel Creep Feeding Accelerates Growth and Alters Intestinal Health of Young Pigs

  Animals · 2022 · 13 citations

  To combat the stress of weaning, we utilized novel gruel creep feeders to supplement suckling pigs with divergent soluble (n = 6 litters) versus insoluble (n = 6) diets compared with un-supplemented controls (n = 6). Post-weaning, pigs were fed a common phase 1 diet. Average daily weight gains of pigs fed soluble and insoluble creep diets were 53% and 17% greater than control pigs, respectively (p < 0.01). Creep intake was higher (82%) for pigs fed the soluble diet, and the accompanying weight i…

• Quantification of the absolute abundance of the jejunal mucosa-associated microbiota of pigs using spike-in control

  Microbiome Research Reports · 2026-03-18

  articleOpen accessSenior author

  The objective was to quantify the absolute abundance of the jejunal mucosa-associated microbiota in pigs and develop a standardized spike-in control protocol. The spike-in control, containing bacteria that are Gram-negative (Imtechella halotolerans) and Gram-positive (Allobacillus halotolerans), was diluted 100 times and 10 μL (100,000 bacterial cells of each species) was added to 100 mg of porcine jejunal mucosa samples. The relative abundance of the jejunal mucosa-associated microbiota differe…
