Abstract

米ヌカ添加ホテイアオイサイレージの飼料価値を検討した。供試サイレージとしては,米ヌカ15%添加サイレージおよび脱脂米ヌカ15%添加サイレージを調製し,肉用育成牛(各3頭)を用いて試験を行った。脱脂米ヌカ添加サイレージの可消化粗タンパク質(DCP)および可消化エネルギー(DE)は,それぞれ9.5%,2.2Mcal/kgであった。米ヌカ添加サイレージのそれは,それぞれ8.9%および2,2Mcal/kgであった。脱脂米ヌカ添加サイレージの自由乾物摂取量は体重の1.3%で,米ヌカ添加サイレージのそれは0.9%であった。また,脱脂米ヌカ添加サイレージの乾物消化率は50.3%,米ヌカ添加サイレージのそれは51.8%であった。従って,DE摂取量は日本飼養標準と比較して,維持要求量を若干下回ったが,DCP摂取量は維持要求量を満たしていた。

The voluntary intake and the digestibility of nutrients of water hyacinth silage prepared by mixing with defatted rice bran (DRB) or rice bran (RB) were investigated. Each silage included the additives at the rate of 15% of fresh matter, and was given to three Japanese Brown heifers ad libitum, respectively. The chemical component of the DRB and the RB-added silages were 9.5% of DCP and 2.2 Mcal/kg of DE in the former and 8.9% of DCP and 2.2 Mcal/kg of DE in the latter. The quality of both silages was high. Voluntary DM intake was 1.3% of body weight per day in the DRB-added silage and 0.9% in the RB-added silage. The digestibilities of DM were 50.3% for the former and 51.8% for the latter. The voluntary intakes of DM and DE were lower than the requirement for maintenance, but DCP intake was higher than the required.
