The different types of sorghum: Sorghum bicolor (L.) Moench (Snow brand hybrid sorgo; Sorgo-common type, Hi-calo sorgo; Dual purpose type, Hi-sugar sorgo; Sorgo-syrup type) were ensiled and their digestibility and rumen fermentation and the effect on blood profile were examined. The results obtained were as follows; (1) All silages had good fermentative quality. (2) It was remarkable, in the comparison of 3 silages of sorghum sown in spring, that Hi-sugar sorgo was rich in protein and in structural carbohydrate which was low lignified and silicified, and was digestible. (3) Silage of sorghum sown in summer was more digestible, especially in protein, than that sown in spring. (4) It was not observed the difference of digestible nutrient content between the whole crop and the ear-removed silages of hybrid sorgo sown in spring. (5) There were significant corelation among the crude protein content of silage, the crude protein digestibility, the DCP content, the VBN content in the rumen and the serum urea content. (6) The digestible silage tended to make to decrease the serum non-esterified fatty acid
