Four Holstein cows in late lactation were offered four diets comprising two levels of crude protein (CP; almost 16.5% and 13.5%) and two levels of protein degradability (replacing the ratio of soybean meal to heat-treated soybean meal as a source of rumen protected protein), and balance trials were conducted. Milk yield and milk fat percentage decreased significantly with reducing CP content in diets, but the degree of decrease were small. Both reduction in dietary CP content and protein degradability showed the effect that significantly decreased urine volume in lactating dairy cows. The effect of dietary CP content on urine volume might be larger than the effect of protein degradability, reflecting a difference in the impact of two treatments on blood urea and ruminal ammonia concentration. Feeding low CP diets caused increase in fecal water excretion, and since this increment could be attributed to lower fiber digestibility in low CP diets, it was thought that the selection of feed source to prepare low CP diet was important.\n", "subitem_description_type": "Abstract"}, {"subitem_description": "窒素 (N) を制御して泌乳牛の尿量を低減化する栄養管理技術の開発を目的に, 飼料タンパク質の給与水準と第一胃分解性の違いが, 泌乳牛の尿量に及ぼす効果について調べた。泌乳後期のホルスタイン種泌乳牛4頭に, 粗タンパク質 (CP) 含量2水準 (概ね16.5% および13.5%) およびタンパク質第一胃分解性2水準 (大豆粕とバイパス大豆粕の比率を入れ替えて調製) を組み合わせた4飼料を給与して, 出納試験を実施した。飼料CP含量の減少によって, 乳量と乳脂肪率に有意な低下が観察されたが, その低下の程度はわずかであった。飼料CP含量の減少と飼料タンパク質の第一胃分解性の低下は, どちらも泌乳牛の尿量を有意に減少させる効果を示した。尿量の低減効果は, 飼料CP含量を減少させる処理の方が, 第一胃分解性の低下処理よりも大きく現れ, これは両処理の血中尿素濃度および第一胃液アンモニア濃度に及ぼす効果の違いが, 反映されたものと考えられた。低CP飼料区において糞中水分排せつ量の増加が観察されたが, この原因は低CP飼料区で用いた飼料の繊維消化率が低かったためと推察され, CP含量を低減する飼料調製では, 飼料源の選択が重要であると考えられた。\n", "subitem_description_type": "Abstract"}]},
