Nutritional Biochemistry

In 1997, Nature published a report of a sheep cloned from an adult cell. In 2001, "mad cow disease" (bovine sponge form encephalopathy: BSE) was discovered in our country, and aroused much controversy.

These and similar events remind us that raising healthy livestock and producing safe animal products is difficult and risky. Cloning technology and embryo transfer are useful technologies for developing livestock, plants or crops with having excellent breeding capacities. However, we need to feed and raise them for a certain time, and many environmental factors, especially nutritional supplies, can influence their growth. In the Laboratoryof Nutritional Biochemistry, we teach and research animal nutrition and the feed responses of animals by studying mechanisms in cells, tissues, and organs.

Our current research foucuses on keeping livestock healthy and produce good quality products. Research topics are : 1) the regulations of energy consumption in chickens; 2) the central nervous system regulation of feeding behavior in chickens; and 3) the mechanisms of the protein synthesis in muscle and liver activated by certain amino acids.
