Kim Moon-seok and the First Private-Farm Hanwoo Candidate Sire
A successor farmer in North Jeolla spent 26 years on selective breeding and in 2024 broke the government breeding farms' hold on Korea's candidate sires.
Who Is Kim Moon-seok?
Kim Moon-seok is a Hanwoo farmer in Singrim-myeon, Gochang County, in North Jeolla Province in southwestern South Korea. In April 2024 the newspaper Segye Ilbo described him as a 51-year-old successor farmer who took over his father's cattle business and raises more than 400 Hanwoo, the native Korean beef breed. This profile rests on that one report, the Segye Ilbo article on his sire selection, and covers his public professional record only.
Starting in 1998
Kim began raising cattle in 1998, during the Asian financial crisis, with animals from his father's herd. After 26 years of selective breeding he says he developed a top-performing bull line. The article frames his career as one continuous project of selection on a family herd that began in 1998.
What a Candidate Sire Selection Means
According to the newspaper's account of the testing, the NH Economic Holdings Hanwoo Improvement Center, a state-recognized bull testing institution, tests bulls twice a year to find those with superior genetics. In the first half of 2024, 36 of 449 bulls were selected as candidate sires, and 35 of those came from breeding farms. Kim entered six bulls in the latest round and one of them was chosen.
That one bull stands out because it is the first time a bull raised on a private farm, rather than a government-managed breeding farm, was chosen nationwide, according to the report. A candidate sire is not yet a final sire: Kim plans to have its offspring tested so it can qualify as a guaranteed sire.
How He Breeds
Kim says he culled weaker lines using genetic testing and kept improving his bulls over time, and that the process takes three to four years. Elite sire semen reportedly sells for up to one million won per artificial insemination, which gives a sense of why a sire selection matters economically for a breeding farm.
The report describes breeding in terms of selection and patience: test, cull and test again.
The Key to Kim's Success
The documented record shows slow, repeated selection on a family herd, tested against an outside standard.
The record is limited. As the only published report available makes clear, it is a single news article, and the candidate sire is only a first step toward guaranteed-sire status.
- He started from his father's herd in 1998 and kept refining the same line for 26 years.
- He used genetic testing to cull weaker lines.
- He entered six bulls in a state-recognized test and let outside evaluation decide.
- He accepted a three-to-four-year cycle for improving each bull.
- He plans to prove the candidate through offspring testing before calling it a guaranteed sire.
What Comes Next
Kim intends to supply semen to farms in struggling regions. A recent revision of the Livestock Act eased licensing for semen processing and sales, which makes this possible.

Because only one source was available, this profile is marked as thin.
