| The Loess Plateau, situated in north-west China, has been subjected to degradation of vegetation owing to overgrazing. In order to clarify the effects of grazing and cutting on vegetation and productivity of shrub-steppe, the study was carried out from May in 1989 to October in 1991 in the Pastoral Preserving Zone of Yunwu Mountain. The vegetation was monthly surveyed, and DM weights of dominant species were separately measured. Soil samples were taken at three selected sites and one overgrazed site and these chemical analysis were made. Relative abundance of species was calculated on the base of the total frequency of 7835. Gramineae showed the highest value (26 %), followed by Compositae (24 %) and Leguminosae (12 %). During 3 experimental years, the... |

| The study was conducted in Obihiro, Japan to examine the position and rate of intestinal fermentation in three adult ostriches (Struthio camelus) with mean liveweight of 103±4.7 kg. The ostriches were fed fresh leaves of orchardgrass (Dactylis glomerata). At twenty five hours before the slaughter, they ingested 100 g fresh leaves mixed with 20 g oblong strips (2mm wide and 30 mm long) of a filter paper, in which chromium oxide was absorbed at a rate of 40 %. After the slaughter, small intestine, cecum and large intestine were cut into 3, 2 and 7 pieces, respectively, with the same length in each organ. Crude ash content in digesta samples was the highest in muscular stomach (90.1±1.17 %), compared with 27-51 % in other organs of glandular stomach, small... |

| The study was carried out to determine tensile and shearing properties of leaves in cultivars (Ba11356 and Ba11358) of festulolium (Festulolium loliaceum), compared with those of diploid (Ba11353 and Aurora) and tetraploid (Ba10855 and Prospero) cultivars of perennial ryegrass (Lolium perenne). Four successive samples of grass leaves were taken from pure stands of third-year swards during July to September, 2004 in Obihiro, Japan. Tensile strength was measured using a 100 N load cell of the breaking test machine. Shear strength was measured about 5 mm apart from a broken point in the tensile test using a pair of the scissors. Cross-sectional area, DM weight and width of leaves were significantly higher in tetraploid perennial and festulolium than in... |
