Abstract

黒毛和種雌牛3頭を用いて,アミノ酸副産液(AABP)処理および発芽処理した完熟期の籾を基礎飼料に乾物で30%配合し消化試験を実施した。その結果, AABP処理籾と発芽処理籾の粗タンパク質消化率は無処理籾よりも高く,発芽処理籾の可溶無窒素物,粗繊維,中性デタージェントおよび酸性デタージェント繊維の消化率は無処理籾より高い傾向があった。AABP処理と発芽処理は籾の消化率を改善することが示唆され,特に発芽処理によりその効果が強く現れる傾向があった。また,発芽処理籾の乾物中可消化養分総量,可消化粗タンパク質および可消化エネルギーは無処理籾より高くなる傾向があった。AABP処理および発芽処理籾とも無処理籾より糞中未消化籾排泄率が低下し,窒素蓄積量が増加する傾向が示された。

By using three Japanese Black cows as test animals, the digestion trial was carried out to examine the nutritive value of treatments of amino acid by-product (AABP) addition and germination in unhulled rice (cv. Haenuki). Experimental rice crop was harvested at a full-ripe stage and compounded to basal diet at 30% on a dry matter basis. Loss of dry matter and energy by germination treatment was as low as about 1% until 3 days after germination. The crude protein digestibility in treatments of AABP and germination was higher and the digestibilities of nitrogen free extract, crude fiber, neutral detergent fiber and acid detergent fiber tended to be higher in germination treatment than in no treatment. As a result, total digestible nutrients, digestible crude protein and digestible energy in germination treatment tended to be higher than in no treatment. The excretion rate of unhulled rice and the accumulation of nitrogen tended to be improved by AABP and germinated treatments. It was suggested that unhulled rice digestibility in cattle would be higher by treatments of AABP addition and germination. It seemed in particular that a digestion improvement effect strongly appeared by germination treatment.
