Research and Development-Developing new technologies and bringing them into practical use

2018/02/09

Breeding and genetic improvement of farm animals by new technology focusing on molecular genetic techique.

Studies are being conducted to identify genes or linked genetic markers affecting economically important traits of farm animals for Japanese food production. Applications to livestock improvement are also being investigated.

The genes identified by NLBC

The gene involving the resistance to mastitis of dairy cattle.

The genes involving the conception rates in cows.

The gene involving the fatty acid composition in beef which affects its taste.

The gene involving the inosine 5′-monophosphate, which contribute to umami taste,

 content in beef.

The gene involving the litter size of swine.

Developing methods for evaluating the taste of meat

In order to improve livestock animals that can produce meat which responds to needs of consumers, researches are being made on development of evaluation methods for the taste of meat, utilizing sensory assessment and physicochemical analysis. Applications to livestock improvement are also being investigated.

Improvement of the livestock reproduction technology

NLBC continually strives to improve livestock performance using new technologies including the areas of animal reproduction, particularly in embryo transfer technology. NLBC focuses on research of Ovum Pick-Up and In Vitro embryo Production(OPU-IVP)for cattle, and also non-surgical transfer of vitrified embryos for pig.

Research on the technology involving husbandry

Researches are being carried out on technologies involving husbandry of animals, production and utilization of forage crop, pasturage and processing and utilization of animal excrements.
