Animal Breeding and Genetics Lab
Machine-translated · View original
A lab studying the breeding and improvement of cattle and pigs based on their genetic mechanisms.

AboutAbout the lab
Guiding animals' genetic ability in a beneficial direction through selection.
The Animal Breeding and Genetics lab clarifies the genetic mechanisms of animals useful to humans, such as cattle and pigs, and researches how breeding improvement can supply inexpensive, delicious, and safe livestock products.
It is one of the few labs in Japan that studies quantitative genetics using statistics.
The lab emphasizes accurately predicting the genetic ability of individual animals and producing offspring with high ability.
It also conducts research that contributes to sustainable livestock production, in order to mitigate and adapt to climate change such as global warming.
Key terms
- Quantitative genetics
- A field that uses statistics to study how animal traits are inherited from parents to offspring.
- Breeding improvement
- The practice of selecting individuals with high genetic ability to produce offspring, raising the ability of the next generation.
- Inbreeding depression
- A phenomenon in which continued mating between closely related individuals lowers performance.

ResearchResearch themes
With the mission of guiding animals' genetic ability toward more beneficial directions through selection, the lab studies livestock populations such as cattle and pigs. To contribute to sustainable livestock production, it also pursues research that draws on the knowledge cultivated in animal breeding and genetics.
*Illustrative imageBreeding technologies for new improvement traits
The lab studies breeding technologies concerning reproductive performance and feed efficiency in beef cattle, mastitis resistance in dairy cattle, methane emission reduction in cattle, and reproductive performance and disease resistance in pigs.
*Illustrative imageDeveloping methods to make breeding more efficient
The lab works on breeding methods that use genomic information and the gut microbiota, and on developing high-throughput phenotyping methods that use spectral data.
*Illustrative imageEvaluating genetic diversity and inbreeding depression
The lab studies methods for evaluating genetic diversity and inbreeding depression, and evaluates diversity in actual livestock populations. It also handles optimal mating methods that take both the amount of genetic improvement and inbreeding into account.
