The K absorption rate in alfalfa silage was 95 to 97% for sheep, but plasma K was not affected by high K absorption. The K absorption rate of sheep fed large amounts of K was maintained at high level, although absorption rates of Ca and P decreased. Maceration improved Ca, P and Mg absorption in sheep. Sixteen multiparous Holstein cows were used, and four cows were assigned to an alfalfa silage diet or an orchardgrass silage diet in Experiment 2 and an alfalfa silage diet or an alfalfa plus corn silage diet in Experiment 3 from 4 weeks prepartum to 1 week postpartum to examine the effect of prepartum diet on the mineral status of periparturient cows. In the prepartum diet, the roughage to concentrate ratio was 70 : 30 of the total diet with alfalfa being 35% in Experiment 1 and 20% in Experiment 2, and dietary K contents ranged from 1.49 to 2.30% in each diet. Milk fever occurred in 2 cows fed the alfalfa diet in Experiment 2, and the occurrence of milk fever may be partly due to the impaired activity of PTH. Plasma Ca, inorganic P and hydroxyproline of the cows with milk fever decreased at parturition, although plasma PTH was not affected by the high K alfalfa diet. Plasma glucose and 1,25-dihydroxyvitamin D of the cows fed the alfalfa plus corn silage diet was higher in Experiment 3. These results suggest that the K absorption rate of ruminants fed alfalfa was high level, and alfalfa plus corn silage diet improve mineral status of periparturient cows because of the increased DM intake and decreased dietary K contents.\n","subitem_description_type":"Abstract"},{"subitem_description":"めん羊15頭を用いて、アルファルファの自由摂取と摩砕処理がミネラル出納に及ぼす影響を調べた（試験1）。アルファルファサイレージ給与時のめん羊のカリウム吸収率は95～97％と非常に高かったが、血漿中のカリウム濃度はカリウム吸収量が増加しても上昇しなかった。カルシウムとリン吸収率は摂取量が増加すると低下したが、カリウム吸収率は高レベルであった。摩砕処理はめん羊のカルシウム、リンおよびマグネシウム吸収量を改善した。経産牛16頭を用いて、分娩前のアルファルファあるいはオーチャードグラスサイレージ主体給与（試験2）およびアルファルファとアルファルファ+トウモロコシサイレージ主体給与（試験3）が乳牛のミネラル栄養に及ぼす影響を調べた。分娩前の粗濃比は30 : 70とし、またアルファルファの給与比率は試験1では35％、試験2では20％に設定した。試験飼料のカリウム含量は1.49～2.30％の範囲内であった。試験2でアルファルファ給与牛2頭に乳熱が発生し、乳熱発生牛では分娩時に血漿中カルシウム、無機リンおよびハイドロキシプロリン濃度が急減した。しかし、血漿中副甲状腺ホルモン濃度は影響されなかったことから、副甲状腺ホルモンの働きを阻害されたことが乳熱発生の一因と思われた。試験3では、アルファルファ+トウモロコシサイレージ給与牛の血漿中グルコースと活性型ビタミンD濃度が高かった。以上の結果から、アルファルファを給与した反芻動物のカリウム吸収率は非常に高いが、妊娠牛にアルファルファとトウモロコシサイレージを組み合わせて給与すると乾物摂取量の増加とカリウム摂取量の低下により、妊娠牛のミネラル栄養が改善すると推察された。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001323","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
