卵巣に嚢腫卵胞を有するホルスタイン種乳牛78頭を発情周期および直腸検査所見から3群に区分し, 各群別の処置により空胎期間の短縮を試みた. 初診日の発情徴候が良好で, 嚢腫卵胞と正常卵胞 (NF) が共存していた39頭 (NF共存群) には無処置で人工授精のみを行った. 初診日に発情徴候がみられず, 嚢腫卵胞と黄体 (CL) が共存していた16頭 (CL共存群) にはジノプロスト (25mg) を投与し, 投与後7日以内に発情が誘起された例には人工授精を行った. 嚢腫卵胞のみが認められた23頭 (卵胞嚢腫群) には, 酢酸フェルチレリン (200μg) 投与後14日にジノプロスト (25mg) を投与し, 発情誘起例に人工授精を行った. NF共存群, CL共存群および卵胞嚢腫群の初診から初回授精までの日数 (平均±SD) は, それぞれ0, 9.3±14.であった. また, 各群の初回授精受胎率は43.6, 43.8, 34.8%であり, 受胎に要した授精回数は1.9±1.1.

The five stone-masonry bridges over the Kotsuki River, which flows along the center of Kagoshima City, have provided a historical outlook to this City. Among them, the Nishida Bridge has ornamental balustrade with beautifully designed balusters and this bridge is very famous as the main gateway bridge of the old Satsuma province. This paper investigates why these stone-masonry bridges were chosen for construction in kagoshima, which lies at the southern edge of Kyusyu, the circumstances of construction of these bridges and so on.

The five stone-masonry arch bridges over the Kotsuki river in Kagoshima city were constructed around 150 years ago and were in use till recently. But two of them were washed out due to the record rainfall which fell in August 1993. Therefore it was decided to carry out river conservation works and move the three remaining bridges to a different place and preserve them there. This paper investigates the changing conditions of the five stone-masonry arch bridges in relation to the variations in social environment from a historical perspective. An attempt is made to understand the cultural significance of present civil engineering structures. The procedure for general agreem6nt regarding the preservation and conservation of historical structures is also discussed.
