https://doi.org/10.5187/jast.2500286
Pain management in dairy cattle remains a persistent challenge, hindered by subjective assessments and inherent observer biases that compromise animal welfare and impose significant economic burdens due to conditions such as mastitis and lameness. Emerging AI technologies, integrated with computer vision and mobile platforms, now offer transformative solutions through objective, automated facial expression analysis. Advancements in neurobiological research have elucidated the mechanisms underlying bovine pain expression, enabling the developmen...

J Anim Sci Technol 2026;68(4):1002-1014.
https://doi.org/10.5187/jast.2500468
Rumen microbiota is essential for nutrient digestion, immune function, and metabolic health in ruminants. With growing interest in sustainable animal production, recent studies have focused on the combined use of diet and probiotics in modulating rumen microbial community and its association with host performance. This review summarizes the effects of dietary strategies on microbial composition and fermentation efficiency. This review also discusses how probiotics such as Saccharomyces cerevisiae, Lactobacillus, Lacticaseibacillus, Lactiplantib...

Livestock immunogenomics based on omics integration: from infection and stress to xenotransplantation
Byeonghwi Lim , Chiwoong Lim , Min-Jae Jang , Young-Jun Seo , Jun-Mo Kim
J Anim Sci Technol 2026;68(4):1015-1050.
https://doi.org/10.5187/jast.2600054
Livestock production systems are increasingly constrained by infectious diseases and environmental stress. These factors compromise productivity, animal welfare, and sustainability under heterogeneous field conditions. Immune-related traits governing disease susceptibility, recovery, and performance loss are polygenic and influenced by diverse conditions. They arise from coordinated responses across multiple tissues and molecular layers. As a result, single-omics approaches often fail to generalize across breeds, environments, and management sy...

J Anim Sci Technol 2026;68(4):1051-1065.
https://doi.org/10.5187/jast.2500118
The variable number tandem repeat (VNTR) LEI0258 is the most polymorphic marker in the chicken major histocompatibility complex (MHC) B region. Unlike other microsatellite markers, LEI0258 is characterized by R13 and R12 repeat motifs, resulting in greater allele variation across chicken breeds. The allele size of this marker can also vary due to deletions and insertions of one to several base pairs. Sanger sequencing of LEI0258 alleles allows for determining exact allele sizes (bp), elucidates its repeat motif combination patterns, reveals oth...

J Anim Sci Technol 2026;68(4):1066-1082.
https://doi.org/10.5187/jast.2500079
In this study, we investigated whether MIT-001, a small-molecule reactive oxygen species (ROS) scavenger, improves the re-expansion and viability of bovine blastocysts in response to vitrification-induced mitochondrial dysfunction and stress. Therefore, this study aimed to analyze the protective effects of MIT-001 on the mitochondrial function of bovine blastocysts following vitrification warming. In this experiment, MIT-001 (0.1 μM) was allocated to three culture conditions based on treatment period: (I) warming only (WARM); (II) vitrificat...

https://doi.org/10.5187/jast.2600012
This study aimed to examine the association of Ras signaling with steroid hormone receptors, angiogenic factors, cell cycle/cell proliferation markers, and apoptotic factors during the estrous cycle in pigs. Porcine corpus luteum (CL) tissues were classified into the early (EP), middle (MP), and late phases (LP). Furthermore, the mRNA and protein expression profiles of steroid hormone receptors, angiogenic factors, cell cycle-related factors, apoptosis-related factors, Ras and Ras GTPases were assessed using reverse transcription-polymerase cha...

J Anim Sci Technol 2026;68(4):1099-1116.
https://doi.org/10.5187/jast.2600045
Mycotoxin contamination of animal feed is a major threat to livestock reproduction. Deoxynivalenol (DON), a trichothecene mycotoxin, disrupts cellular function by binding to ribosomes and inducing ribotoxic stress, oxidative imbalance, and apoptosis. Its primary microbial metabolite, deepoxy-deoxynivalenol (DOM-1), is thought to be less toxic. However, its reproductive effects remain unclear. DON contamination is widely reported in cereal grains used in animal feed, and pigs exposed to contaminated diets have been shown to exhibit detectable DO...

J Anim Sci Technol 2026;68(4):1148-1163.
https://doi.org/10.5187/jast.2025.e41
Dietary zinc oxide (ZnO) is widely adopted in the swine industry to alleviate post-weaning diarrhea and promote the growth performance of weaned pigs. However, its low rate of absorption in the gastrointestinal tract leads to excessive excretion, which causes severe environmental pollution. To overcome this limitation, dietary coated ZnO (CZO) has been studied to enhance zinc absorption and mitigate its environmental influence. In the present study, we investigated the effects of dietary CZO on growth performance, frequency of diarrhea, nutrien...

https://doi.org/10.5187/jast.2600013
Methane is a major greenhouse gas with a global warming potential 28 times greater than that of carbon dioxide, making reduction of livestock emissions a critical challenge. Current mitigation strategies, such as feed management, chemical additives, and algae supplementation, face limitations related to safety, supply instability, and economic feasibility. To address these issues, we investigated the development of methane-reducing feeds utilizing synbiotics. In a preliminary study, we evaluated the methane reduction potential of Komagataeibact...

The daily requirement for minerals is minor; nevertheless, they are essential for the metabolism, growth, and reproduction of dogs. Therefore, European Pet Food Industry Federation, Nutrient Research Council, and Association of American Feed Control Officials (AAFCO) recommend minimum levels of essential minerals in pet food. This study examined the potential availability and safety of organic minerals in adult dogs. Five-year-old, neutered female beagle dogs were fed an inorganic (IMD) or organic (OMD) mineral-based diet twice daily for two we...
