Genome editing has been considered as powerful tool in agricultural fields. However, genome progress cattle not fast other mammal species, for some disadvantages including long gestational periods, single pregnancy, and high raising cost. Furthermore, technically demanding methods such microinjection somatic cell nuclear transfer (SCNT) are needed gene cattle. In this point of view, electroporation embryos risen an alternative.First, efficiency our were tested embryos. Presence mutation on...
Many genome-edited animals have been produced using clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 technology to edit specific genes. However, there are few guidelines for the application of this technique cattle. The goal study was produce trait-improved cattle genome-editing CRISPR-Cas9. Myostatin (MSTN) selected as a target locus, and synthetic mRNA sgRNA Cas9 were microinjected into fertilized bovine embryos in vitro. As result, 17 healthy calves born, three them...
Diabetes is characterized by hyperglycemia due to impaired insulin secretion and aberrant glucagon resulting from changes in pancreatic islet cell function and/or mass. The aim of the present study was investigate effects ginger on various tissues (i.e., pancreas, kidney, liver) resistance streptozotocin-induced diabetic mice. pleasant aroma comes constituents its volatile oil, while non-volatile pungent phytochemicals consist gingerols, shogaols, paradols.This research conducted determine...
This study aimed to identify genetic associations with carcass traits in Hanwoo cattle using a genome-wide association study. A total of 9302 phenotypes were analyzed, and all animals genotyped the Illumina Bovine 50K v.3 SNP chip. Heritabilities for weight (CWT), eye muscle area (EMA), backfat thickness (BF), marbling score (MS) estimated as 0.42, 0.36, 0.47, respectively, GBLUP model, 0.37, Bayes B model. We identified 129 common SNPs DGEBV 118 GEBV on BTA6, BTA13, BTA14, suggesting their...
Conducting genome-wide association studies (GWAS) for reproductive traits in Hanwoo cattle, including age at first calving (AFC), interval (CI), gestation length (GL), and number of artificial inseminations per conception (NAIPC), is paramount significance. These analyses provided a thorough exploration the genetic basis these traits, facilitating identification key markers targeted trait improvement. Breeders can optimize their selection strategies, leading to more efficient sustainable...
Visual estrus observation can only be confirmed at a rate of 50%–60%, which is lower than that obtained using biosensor. Thus, the use biosensors provides more opportunities for artificial insemination because it easier to confirm by visual observation. This study determines accuracy prediction ruminoreticular biosensor analyzing temperature during cycle and measuring changes in body activity. One hundred twenty-five Hanwoo cows (64 with ruminal test group 61 without control group) were...
Abstract Chicken, Gallus gallus , is a valuable species both as food source and model organism for scientific research. Here, we sequenced the genome of Gyeongbuk Araucana, rare chicken breed with unique phenotypic characteristics including flight ability, large body size, laying blue-shelled eggs, to identify its genomic features. We generated genomes Leghorn, Korean Native Chicken at total 33.5, 35.82, 33.23 coverage depth, respectively. Along 12 Chinese breeds, identified variants 16.3...
Fat quality is determined by the composition of fatty acids. Genetic relationships between this and single nucleotide polymorphisms (SNPs) in stearoyl-CoA desaturase1 (SCD1) gene were examined using 513 Korean native cattle. Single epistatic effects 7 SNP genetic variations investigated, multifactor dimensionality reduction (MDR) method was used to investigate interactions terms oleic acid (C18:1), mono-unsaturated acids (MUFAs) marbling score (MS). The g.6850+77 A>G g.14047 C>T identified...
The thyroid hormone responsive protein (THRSP) gene is a functional that can be used to indicate the fatty acid compositions. This study investigates relationships of exonic single nucleotide polymorphisms (SNPs) in THRSP and composition muscle fat marbling score 612 Korean cattle. between eight SNPs (g.78 G>A, g.173 C>T, g.184 g.190 C>A, g.194 g.277 C>G, g.283 T>G g.290 T>G) were investigated, according results, two G>A C>T) exon 1 associated with composition. GG CC genotypes g.78 C>T had...
Chicken is one of the most popular domesticated species worldwide, as it can serve an important role in agricultural well biomedical research fields. Because inhabits almost every continent and presents diverse morphology traits, need genetic markers for distinguishing each breed various purposes has increased. The whole genome sequencing three different breeds (White Leghorn, Korean domestic, Araucana) that show similar coloring patterns, with exception White Leghorn breed, have confirmed...
Vaccination against foot-and-mouth disease is the most common method for preventing spread of disease; negative effects include miscarriage, early embryo death, lower milk production, and decreased growth fattening cattle. Therefore, in this study, we analyze side vaccination by determining acute immune response ovulation rate after vaccinating cows disease. The test axis was synchronized with using 100 Hanwoo (Bos taurus coreanae) from Gyeongsangbuk-do Livestock Research Institute; only...
This study explored the correlation between Anti-Müllerian Hormone (AMH) levels and reproductive efficiency in native Korean cattle (Hanwoo) as potential oocyte donors Ovum Pick-Up (OPU) programs. In an effort to enhance of colletion, this research AMH various factors, including quantity follicles, retrieved oocytes, proportion transferable embryos. A total 42 Hanwoo cows were included with ranging from 276.5 2212.5 pg/mL. These categorized into three groups based on concentration: high (H),...

Abstract Background In Korean cattle, after foot‐and‐mouth disease (FMD) vaccination, anovulation increases, acute immune response is stimulated. Objective Here, we aimed to improve the fertility rate by ovulation delay caused vaccine. Methods 160 cows (control, FMD, FMD+Gn250 and FMD+Gn500 groups, with 40 each) were used. We analysed delay, rate, conception acute‐phase responses. Results group vaccinated only average follicle size was maintained at 12 mm delayed. The of (500 μg...
This study aimed to predict the accuracy of genomic estimated breeding values (GEBVs) for reproductive traits in Hanwoo cows using GBLUP, BayesB, BayesLASSO, and BayesR methods. Accuracy estimates GEBVs were derived through fivefold cross-validation, analyzing a dataset comprising 11,348 animals employing an Illumina Bovine 50K SNP chip. GBLUP showed 0.26 AFC, while demonstrated 0.28, 0.29, respectively. For CI, attained 0.19, whereas scored 0.21, 0.24, 0.25, The GL was uniform across at...
