Five, 10, 15, 20 or 25 leaf blade sections per loadcell from basal and middle parts were offered to sheep. The three-dimensional biting forces were digitally recorded at 0.006-second intervals using the threedimensional loadcell. DM weight per mean biting force (benefit/cost ratio) was not significantly different among any treatments, and its grand mean was 16.7±1.1 mg-DM/N. There was a significant correlation between bending strength and shearing strength, strongly suggesting that sheep may recognize chewing ease of leaf blade sections through sensing bending strength prior to prehension and adjust leaf number per bite and biting force. This hypothesis was supported by the result that 87 % of a total of 173 bites were completed by only one peak biting force. Biting force per leaf used by sheep was 2.53±0.37 N and 1.98±0.26 N in the basal and middle sections, respectively. Shearing strength per leaf was 3.35±0.20 N and 1.93±0.19 N in the basal and middle sections, respectively. These results suggest that sheep break-down leaves principally using shearing force.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"オーチャードグラス葉身の曲げ強度とせん断強度が採食時のヒツジが使うバイト強度におよぼす影響を明らかにするために実験を行った。葉身の基部と中間部を5、10、15、20、25枚づつ1個のロードセルに取り付け、ヒツジに採食させた。3方向のバイト強度を0.006秒間隔でデジタルで記録した。平均バイト強度あたりのDM 重を、利潤/ 投資比率として計算すると、各処理間で有意な差はなく、全体の平均値は16.7±1.1 mg-DM/ N であった。葉身の曲げ強度とせん断強度との間には有意な正の相関があった。この結果は、ヒツジは採食の直前に曲げ強度を感知することで葉身の破断のしやすさを判別しており、口の中に入れる葉の枚数と、そのあとの破断に使う力を決めていることを示唆している。このような仮説は、全体の173バイトのうち87% のバイトでは1回の試みですべての葉身を破断していた結果からも支持された。ヒツジが使用したバイト強度を、その時食べた葉身の枚数で割り、葉身1枚あたりのバイト強度を求めると、基部の葉身で2.53±0.37 N、中間の葉身で1.98±0.26 N であった。葉身1枚のせん断強度は基部の葉身で3.35±0.20N であり、中間の葉身で1.93±0.19 N であった。このような結果から、ヒツジは下顎の切歯の鋭さを有効に使って、せん断する方法で牧草を採食しているものと推察された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Obihiro
