 note = {出穂期に刈取ったローズグラス,グリーンパニック,イタリアンライグラスの乾草を調製し,ホルスタイン種泌乳牛を用い,反転試験法により摂取量,乳量,乳組成について調査した.実験1でローズグラスとイタリアンライグラス,実験2でグリーンパニックとイタリアンライグラスの産乳性を比較するとともに､ルーメン内液の性状について検討した.飼養試験では乾草を自由採食させ,濃厚飼料を乳量の1/5相当量給与した.得られた結果を要約すると下記のとおりである.1)各乾草の品質は中程度であった.イタリアンライグラスの葉部割合は他の2草種より多少低かった.供試3草種中グリーンパニックのDCPとTDN含量は最も高く,イタリアンライグラスのDCP含量とローズグラスのTDN含量はともに最低であった. 2)乾草の採食量はグリーンパニックが最も高く,他の2草種は互いに近似した.3)実乳量とFCM量はグリーンパニック区がイタリアンライグラス区より有意に高く,ローズグラス区はイタリアンライグラス区より有意に低かった.4)乳脂率はローズグラス区とグリーンパニック区がイタリアンライグラス区より有意に高かった.5)ルーメン内液のアンモニア濃度はイタリアンライグラス区が他の2区より有意に低かった., Rhodesgrass (Chloris gayana Kunth. cv. Katambora), green panic (Panicum maximum Jacq. var. trichoglume cv. Petrie) and Italian ryegrass (Lolium ultiflorum Lam cv. Wasehikari) hays were prepared at the heading stage. To evaluate the feeding value of these hays for lactating cows, two feeding trials (Rhodesgrass vs. Italian ryegrass, and green panic vs. Italian ryegrass) were carried out by swich-back design with 3 periods of each 21days duration. The Holstein cows were fed the hays ad libitum, with 1kg of concentrate per 5kg of actual milk per cow daily. The main results obtained were as follows: (1)The experimental bays were average in quality, but Italian ryegrass hay had slightly lower leaf content than the two other bays. Green panic hay contained more DCP and TDN than the two other bays. Italian ryegrass hay was lowest in DCP content and also Rhodesgrass hay in TDN content. (2)The hay dry matter consumption was greater for green panic hay than for the two other hays, whose consumptions were similar. (3)The cows fed the green panic hay produced significantly more milk than the cows fed Italian ryegrass hay, on the other hand, the cows fed the latter hay produced significantly more milk than the cows fed Rhodesgrass hay. (4)Milk fat content was significantly higher for the cows fed Rhodesgrass or green panic hays than for the cows fed Italian ryegrass hay. (5)The concentrations of ruminal ammonia of cows fed Italian ryegrass hay were significantly lower than those of cows fed the two other hays.},
