Outline of Final Research Achievements

Focusing on energy possessed in glycerol and its characteristic pathway in the rumen of ruminants, the effects of supplemental glycerol on rumen fermentation characteristics and blood glucose and amino acid metabolism were measured in cows and sheep both before and after establishment of rumen functions. Effect of heat exposure was also determined in mature sheep. Rumen fermentation characteristics were influenced and blood glucose metabolism were enhanced when the higher level of glycerol supplementation (7%). However, the impacts were limited, when lower levels of glycerol were supplemented (2- 5%).
