  • Whole genome screening for deleterious alleles in Hanwoo cattle

    John Kariuki Macharia, Dong Jae Lee, Seung Hwan Lee, Jun Heon Lee

    Selective breeding of cattle increases the level of inbreeding and, as a result, the risk of transmitting deleterious recessive alleles in a population. Numerous genetic disorders have been identified in various breeds of cattle. Although these disorders occur sporadically, the widespread use of …

  • Comparative analysis of the heritability, estimated breeding value, and accuracy of carcass traits in Hanwoo from the Yeongnam Region, considering breeding area and climate effects, utilizing genomic information

    Ji Yeong Kim, Eun Ho Kim, Ho Chan Kang, Cheol Hyun Myung and Hyun Tae Lim

    Climate change is causing abnormal weather patterns worldwide. In Korea, local governments are characterized by various climatic conditions. Therefore, research integrating climate factors with Hanwoo is necessary. In this study, 562 Hanwoo were analyzed using Pedigree Best Linear …

  • Selection of informative markers using machine learning approaches and genome-wide association studies to improve genomic prediction in Hanwoo cattle: a simulation study

    Waruni Ekanayake, Phuong Thanh N. Dinh, Jun Heon Lee, Seung Hwan Lee

    The present study deploys a comparison of Gradient Boosting Machine (GBM), Extreme Gradient Boosting (XGBoost), and Genome Wide Association Studies (GWAS) in selecting optimum subsets of single nucleotide polymorphisms (SNPs) to be used in genomic prediction in cattle. The data simulation was …
