Coping with large litters: management effects on welfare and nursing capacity of the sow

Olli Peltoniemi, Taehee Han, Jinhyeon Yun

J Anim Sci Technol 2021;63(2):199-210.
https://doi.org/10.5187/jast.2021.e46

A number of management issues can be used as drivers for change in order to improve animal welfare and nursing capacity of the hyperprolific sow. Group housing of sows during gestation is a recommended practice from the perspective of animal welfare. Related health issues include reproductive health and the locomotor system. It appears that management of pregnant sows in groups is challenging for a producer and considerable skill is required. We explored the benefits and challenges of group housing, including feeding issues. Increasing litter s...

Heat stress on microbiota composition, barrier integrity, and nutrient transport in gut, production performance, and its amelioration in farm animals

Amlan Kumar Patra, Indrajit Kar

J Anim Sci Technol 2021;63(2):211-247.
https://doi.org/10.5187/jast.2021.e48

Livestock species experience several stresses, particularly weaning, transportation, overproduction, crowding, temperature, and diseases in their life. Heat stress (HS) is one of the most stressors, which is encountered in livestock production systems throughout the world, especially in the tropical regions and is likely to be intensified due to global rise in environmental temperature. The gut has emerged as one of the major target organs affected by HS. The alpha- and beta-diversity of gut microbiota composition are altered due to heat exposu...

Genetic assessment of BoLA-DRB3 polymorphisms by comparing Bangladesh, Ethiopian, and Korean cattle

Ayele Mandefro, Tesfaye Sisay, Zewdu Edea, Md. Rasel Uzzaman, Kwan-Suk Kim, Hailu Dadi

J Anim Sci Technol 2021;63(2):248-261.
https://doi.org/10.5187/jast.2021.e37

Attributable to their major function in pathogen recognition, the use of bovine leukocyte antigens (BoLA) as disease markers in immunological traits in cattle is well established. However, limited report exists on polymorphism of the BoLA gene in zebu cattle breeds by high resolution typing methods. Thus, we used a polymerase chain reaction sequence-based typing (PCR-SBT) method to sequence exon 2 of the BoLA class II DRB3 gene from 100 animals (Boran, n = 13; Sheko, n = 20; Fogera, n = 16; Horro, n = 19), Hanwoo cattle (n = 18) and Bangladesh ...

Vacuolar H(+)-ATPase is not restricted to clear cells of the epididymal epithelium in cattle

Sung Woo Kim, Bongki Kim

J Anim Sci Technol 2021;63(2):262-271.
https://doi.org/10.5187/jast.2021.e32

Communication among epididymal epithelial cells creates the best luminal condition where spermatozoa mature, transport and are stored. Vacuolar ATPase (V-ATPase) and cytokeratin 5 (KRT5) have been used as signal indicators for clear and basal cells of the epididymal epithelium, respectively, in mice, rats, bats, and pigs; however, these two markers have not yet been described in the epididymis of bulls. Here, we examined the presence and distribution of the B1 subunit of V-ATPase (B1-VATPase) and KRT5 in the distinct regions of adult bovine epi...

Toxicity of the recombinant human hyaluronidase ALT-BC4 on embryonic development

Ji Hye Lee, Miyoun Yoo, Sang Mee Lee, Soon-Jae Park, Tae Young Kil, Min Kyu Kim

J Anim Sci Technol 2021;63(2):272-280.
https://doi.org/10.5187/jast.2021.e34

Cumulus-oocyte complexes (COCs), which contain immature oocytes, are matured in vitro for in vitro embryo production. Oocyte and cumulus cells are then separated using hyaluronidase. To date, there have only been a few reported cases of the toxic effects of hyaluronidase on porcine oocytes. The aim of this study was to compare the effects of bovine testis-derived hyaluronidase and recombinant human hyaluronidase on oocyte denudation and quality. Porcine COCs were matured for 44 h and denuded using different hyaluronidase concen...

Application of the modified handmade cloning technique to pigs

Eun Ji Lee, Kuk Bin Ji, Ji Hye Lee, Hyun Ju Oh, Tae Young Kil, Min Kyu Kim

J Anim Sci Technol 2021;63(2):281-294.
https://doi.org/10.5187/jast.2021.e41

Although somatic cell nuclear transfer (SCNT) is frequently employed to produce cloned animals in laboratories, this technique is expensive and inefficient. Therefore, the handmade cloning (HMC) technique has been suggested to simplify and advance the cloning process, however, HMC wastes many oocytes and leads to mitochondrial heteroplasmy. To solve these problems, we propose a modified handmade cloning (mHMC) technique that uses simple laboratory equipment, i.e., a Pasteur pipette and an alcohol lamp, applying it to porcine embryo cloning. To ...

Effects of acute heat stress on salivary metabolites in growing pigs: an analysis using nuclear magnetic resonance-based metabolomics profiling

Byeonghyeon Kim, Hye Ran Kim, Ki Hyun Kim, Sang Yun Ji, Minji Kim, Yookyung Lee, Sung Dae Lee, Jin Young Jeong

J Anim Sci Technol 2021;63(2):319-331.
https://doi.org/10.5187/jast.2021.e23

Heat stress (HS) causes adverse impacts on pig production and health. A potential biomarker of HS is required to predict its occurrence and thereby better manage pigs under HS. Information about the saliva metabolome in heat-stressed pigs is limited. Therefore, this study was aimed to investigate the effects of acute HS on the saliva metabolome and identify metabolites that could be used as potential biomarkers. Growing pigs (n = 6, 3 boars, and 3 gilts) were raised in a thermal neutral (TN; 25°C) environment for a 5-d adaptation period (CON...

Oxytocin (OXT) and serotonin (5-HT) are essential neurotransmitters associated with the behavior of animals. Recently, we found that the plasma concentration of OXT is positively correlated with horse docility and friendliness toward humans. However, the relationships between the neurotransmitters and other temperaments such as fearfulness, dominance, and trainability are unknown. This study aimed to identify whether the plasma concentration of OXT or 5-HT is correlated with fearfulness, dominance, and trainability of horses. Blood samples of 3...
