The intestinal epithelium performs vital functions such as nutrient absorption and acting as an intestinal barrier to maintain the host's homeostasis. Mycotoxin, which affects the processing and storage of animal feedstuff, is a problematic pollutant in farming products. Ochratoxin A generated by and fungi causes inflammation, intestinal dysfunction, decline in growth, and reduced intake in porcine and other livestock.

Article Synopsis
  • Chromium (Cr) is a toxic metal that affects plant growth by disrupting nutrient uptake and other physiological processes, leading to reduced agricultural yields.
  • The study investigates the effects of different Cr concentrations and hydrogen sulfide (HS) application on two mungbean varieties, revealing that HS mitigates Cr-related damage by enhancing growth, antioxidant activity, and nutrient uptake.
  • Results indicate that HS treatment reduces oxidative stress and Cr accumulation in plants, suggesting its potential role in developing strategies to improve heavy metal tolerance in crops.

Autophagic activation in porcine oocytes is independent of meiotic progression.

Zygote

August 2023

Department of Animal Sciences, College of Agriculture and Life Science, Jeonbuk National University, Jeonju, 54896, Republic of Korea.

In this study, we built on our previous research that discovered that autophagy activated the metaphase I stage during porcine oocytes maturation. We investigated the relationship between autophagy and oocyte maturation. First, we confirmed whether autophagy was activated differently by different media (TCM199 and NCSU-23) during maturation.

  • In South Korea, recent pig-to-primate kidney transplantation trials have shown initial results that are not yet sufficient for clinical application, with 30 surgeries conducted since 2011 at Konkuk University Hospital.
  • Researchers used genetically modified pigs to create organs and administered various immunosuppressants to prevent rejection in cynomolgus monkey recipients.
  • Although the average survival of the transplanted kidneys was 50 days, these results are noted to be the best recorded in the country, with ongoing efforts to enhance the outcomes and move towards clinical trials.

Background: The study evaluated the effects of bacteriophage cocktail (BP) and ZnO administered during weaning time for piglets exposed to a non-sanitary environment. The bacteriophages were designed to eliminate Escherichia coli (K88, K99 and F41), Salmonella (typhimurium and enteritidis), and Clostridium perfreingens (types A and C). Forty 21-day-old crossbreed piglets were assigned to four treatments, including the PC (sanitary environment), NC (non-sanitary environment), BP (NC plus 10 pfu/kg BP), and ZO (NC plus 2,500 mg/kg ZnO).

Article Synopsis
  • The study examines the graft survival rates of full-thickness versus lamellar corneal xenotransplantation (XTP) using genetically engineered pigs in monkey recipients.
  • Results showed that lamellar XTP had significantly longer graft survival times compared to full-thickness XTP, with survival times of over 463 days versus 21 days, though not as high as previous lamellar studies.
  • The findings suggest that lamellar XTP avoids certain surgical complications associated with full-thickness XTP, but further research is needed to enhance graft survival rates and explore the impacts of different transgenic types.

Influence of Dairy Manure as Inoculum Source on Anaerobic Digestion of Swine Manure.

Bioengineering (Basel)

March 2023

Division of Animal and Dairy Science, Chungnam National University, Daejeon 34134, Republic of Korea.

Inoculation is a widely used method to improve the efficiency of anaerobic digestion (AD) with a high organic load. This study was conducted to prove the potential of dairy manure as an inoculum source for AD of swine manure. Furthermore, an appropriate inoculum-to-substrate (I/S) ratio was determined to improve methane yield and reduce the required time of AD.

Deoxynivalenol (DON) is known as a vomitoxin, which frequently contaminates feedstuffs, such as corn, wheat, and barley. Intake of DON-contaminated feed has been known to cause undesirable effects, including diarrhea, emesis, reduced feed intake, nutrient malabsorption, weight loss, and delay in growth, in livestock. However, the molecular mechanism of DON-induced damage of the intestinal epithelium requires further investigation.

Effects of dry period length on milk production and physiological responses of heat-stressed dairy cows during the transition period.

J Anim Sci Technol

January 2023

Department of Agricultural Biotechnology and Research Institute of Agriculture and Life Science, Seoul National University, Seoul 08826, Korea.

The objective of this study was to investigate the effects of a traditional dry period (60 d) versus a no dry period (0 d) on the milk production, physiological response, and metabolic status of dairy cows exposed to heat stress during the transition period. Holstein dairy cows (n = 15) with similar expected calving dates were randomly assigned to two different dry period lengths: (1) no dry period (n = 7) and (2) a traditional dry period of 60 days (n = 8). All cows were studied from 8 weeks before expected calving to 10 weeks after calving and experienced heat stress during the transition period.

Flavor is an important sensory trait of chicken meat. The free amino acid (FAA) and nucleotide (NT) components of meat are major factors affecting meat flavor during the cooking process. As a genetic approach to improve meat flavor, we performed a genome-wide association study (GWAS) to identify the potential candidate genes related to the FAA and NT components of chicken breast meat.

Korea, located in East Asia in the northern hemisphere, is experiencing severe climate changes. Specifically, the heat stress caused by global warming is negatively affecting the dairy sector, including milk production and reproductive performance, as the major dairy cattle Holstein-Friesian is particularly susceptible to heat stress. Here, we collected artificial insemination and pregnancy data of the Holstein and the Jersey cows from a dairy farm from 2014 to 2021 and analyzed the association between the conception rate and the temperature-humidity index, calculated using the data from the closest official weather station.

Many studies have been conducted to improve technology for semen cryopreservation in pigs. However, computer-assisted analysis of sperm motility and morphology is insufficient to predict the molecular function of frozen-thawed semen. More accurate expression patterns of boar sperm proteins may be derived using the isobaric tags for relative and absolute quantification (iTRAQ) technique.
