Transmission Ratio Distortion Detection Using Microsatellite and Single Nucleotide Polymorphism Markers in Hanwoo of Gyeongnam Province. [PDF]

Anim Genet
ABSTRACT This study aimed to identify and compare transmission ratio distortion (TRD) patterns using microsatellite (MS) markers and single nucleotide polymorphism (SNP) markers in a Hanwoo population from Gyeongnam Province. The objective was to construct parent‐offspring trios and investigate TRD patterns that may influence mortality and economic ...

Reproductive and Perinatal Outcomes of Embryo Transfer in Elite Hanwoo Cows. [PDF]

Vet Med Sci
Reproductive outcomes following embryo transfer in Elite Hanwoo cows differed by embryo production method. OPU‐IVF was associated with higher abortion, increased birth weight of male calves and greater dystocia risk, whereas MOET resulted in more favourable calving outcomes, highlighting the importance of embryo production strategy and periparturient ...

Development and External Validation of a Predictive Model of Severe Neonatal Calf Diarrhea in Hanwoo Calves Using Animal, Environmental, and Management Risk Factors. [PDF]

J Vet Intern Med
ABSTRACT Background Neonatal calf diarrhea accounts for most pre‐weaned calf losses in Hanwoo cattle. A novel predictive model of severe neonatal calf diarrhea will help veterinarians and farmers prevent disease in calves. Hypothesis/Objectives Development and external validation of a simple predictive model for severe neonatal calf diarrhea in Hanwoo ...

Copy Number Variation Frequency Analysis by Regions of Hanwoo (Korean Native Cattle) Using Hanwoo SNP 50K Chip

Journal of Animal Breeding and Genomics, 2023
Recently another type of genetic polymorphism, called copy number variation (CNV), has been discovered in the whole genome variation. SNP chips have also been used for CNVs analysis, making them a useful analytical tool. In this study, we evaluated CNVs and identified the relationship between CNV regions (CNVRs) in Hanwoo (n=1500) using the Illumina ...

Study on Ovum-pick up for Improvement of Embryo Transfer Efficiency in Hanwoo Cows

Journal of Animal Reproduction and Biotechnology, 2017
Commercial applications of OPU/IVP were to produce embryos and calves from high genetic cows. The aim of this present study was to compare the number of recovered oocytes and cultured in vitro produced embryos from Ovum Pick-up (OPU).

Developmental and survivability according to cryopreservation of in vitro produced bovine embryos cultured by addition of Antioxident cysteine

Journal of Animal Reproduction and Biotechnology, 2016
The study aims to assess the embryo development and survivability of bovine embryos cultured in vitro by addition of cysteine. The rates of metaphase II formation are not significantly different among the three groups(73.8% for TCM199, 76.9% for TCM199 ...

Harlequin Ichthyosis in a HanWoo Calf

Journal of Veterinary Medical Science, 2007
Ichthyosis (fish scale disease) is a rare hereditary disease and characterized by excessive cutaneous scale formation. A male HanWoo calf born by natural service was found with fissures and thickened, scaly, cutaneous plates covering over 90% of its body.

Scans for signatures of selection in Russian cattle breed genomes reveal new candidate genes for environmental adaptation and acclimation [PDF]

, 2018
Domestication and selective breeding has resulted in over 1000 extant cattle breeds. Many of these breeds do not excel in important traits but are adapted to local environments.
