| ウマの後腸内に水溶性炭水化物(WSC)が大量に流 れ込むと、代謝障害を引き起こす可能性が指摘されて いる。牧草中のWSC含量は乾草などに比べて生草で 高く、また同じ牧草でも季節によって変化することが 知られている。本研究では放牧草中のWSC含量、およ びそれらを採食したウマの後腸内発酵性状の指標とし て糞性状を測定し、季節聞で比較した。調査は日高管 内のサラブレッド種生産農家5戸の繁殖雌馬用放牧地 と、そこで放牧飼養されている繁殖雌馬(のべ98頭) を用い、5、7、9月に行った。放牧草中WSC含量は 7月、9月(13.4、9.3%DM)に比べて5月(19.2%DM) に高かった(p<O.05) 。糞の乳酸濃度は504~729μg/g DMと季節聞で有意な差はなかったが、総VFA濃度は 5月、7月、9月の順に高かった(p<O.05)。糞のpH は7月(6.35)、9月(6.42)に比べて5月(6.08)に低 かった(p<O.05)。放牧草中WSC含量が15%DMを上回 るとき、糞のpHは低下する傾向がみられた。放牧草中 WSC含量が高い春はもちろん、夏、秋においても15% DM程度にまでWSC含量が高くなる場合、ウマの放牧 飼養管理に注意を払う必要があることが示唆された。 It is pointed out the overflow of water-soluble carbohydrates (WSC) into hindgut may cause the metabolic disorders in horses. It is known that the WSC contents in fresh grasses are higher than those in hay，and the... |

| The objective of this study was to evaluate the agronomic characteristics, bromatological-chemical composition and digestibility of 11 corn cultivars (Zea mays) harvested at two cutting heights. Cultivars D 766, D 657, D 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, CO 9621 and BR 205 were evaluated when they were harvested 5 cm above ground (low) and 5 cm below the insertion of the first ear (high). The experiment was designed as random blocks, with three replicates, arranged in an 11 x 2 factorial scheme. Cultivars presented similar productions of forage dry matter and grains. Percentages of stalk, leaf, straw, cob and kernel fractions were different among cultivars, as well as dry matter content of the whole plant at harvest. Considering the whole... |

| Sugar cane silages are characterized by extensive yeast activity, alcohol production and great dry matter - DM - losses. Better knowledge of the fermentation process is fundamental to the development of efficient ensilage techniques for this forage. This study evaluates temporal changes in chemical composition, DM losses and epiphytic microflora in sugar cane silage. Mature sugar cane, variety RB835486 (12 months of vegetative growth), was hand harvested, processed in a stationary chopper and ensiled in 20-L plastic buckets provided with valves for gas release and a device for effluent collection. Laboratory silos were kept at ambient temperature and sampled after ½, 1, 2, 3, 7, 15, 45, 90, 120 and 180 days. Ethanol concentration reached 6.4% in DM after... |
