However excretion in urine (UN), milk urea nitrogen (MUN) and plasma urea nitrogen (BUN) increased as dietary CP contents increased. 2) The relationship between UN (g / day) and CP contents (%) ,MUN (mg/dl) or BUN (mg/ dl) was UN=22.0 CP-208.9 (r²=0.84) ,UN=16.2 MUN-77.5 (r²=0.78),UN=8.8 BUN+18.6 (r²=0.77), respectively. 3) Nitrogen emission from manure tended to increase as CP content increased. In conclusion, the reducing dietary CP content in cows is a way to reduce nitrogen excretion and nitrogen emission without the suppression of productivities of lactating cows.","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"飼料中粗蛋白質（CP）含量が14.4%，15.7%および19.4%の混合飼料を用いて，飼料中のCP含量の違いが乳生産性，糞尿中への窒素排泄量および糞尿由来のアンモニアを主体とする窒素揮散量に及ぼす影響について検討したb 実験には初産泌乳牛4頭を供試して，供試家畜をブロック因子， CP水準の違いを処理因子として取り上げ， L9直交表計画に準じて出納試験を実施した。その結果， l) CP水準の違いは乳生産性に影響を及ぼさなかった。しかし，尿中窒素排泄量 (UN），乳中尿素窒素（MUN）および血漿中尿素窒素(BUN）濃度はCP水準の上昇とともに1%あるいは5%水準で有意に高まった。 2) UN (g/day）と飼料中のCP含量(CP, %), MUN (mg/dl) およびBUN(mg/dl)の間で， UN=22.0 CP-208.9(r²=0.84），UN=I6.2 MUN-77.5(r2=0.78)， UN=8.8 BUN+18.6 (r²=0.77）の関係式が得られた。3) CP水準の上昇とともに糞尿由来窒素揮散量は増加する傾向が見られた。以上のことから，生産性に影響を及ぼさない範囲での給与飼料の低蛋白質化は窒素排泄量および窒素揮散量の低減を実現することが示された。","subitem_description_type":"Other"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001968","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
