The cows were kept under  thermoneutral temperature (18℃） for fourteen days and then exposed to hot temperature (28℃) for the following two weeks; the relative humidity in both temperatures was 60%. The results showed that urinary allantoin excretion correlated with dry matter intake (r= 0.76, Pく.05) and nitrogen intake (r= 0. 71, Pく.05), while concentration of urinary creatinine correlated with decreased body weight(r = 0.83, Pく .05) as a proof of body tissue mobilization. In the hot environmental temperature, allantoin excretion in urine decreased. However, the utilization rate of nitrogen for microbial nitrogen synthesis during heat exposure increased on average from 63.4 % (at 18℃) t0 75.6 % (28℃）. Microbial nitrogen synthesis per digestible organic matter intake increased on average from 20.4 (at 18℃) to 23.0 gN (28℃). The utilization rate of nitrogen and digestible organic matter intake for microbial nitrogen synthesis during the heat exposure increased as the heat exposure was prolonged.","subitem_description_type":"Abstract"},{"subitem_description":"暑熱環境下における尿中アラントイン排泄量の変動を４頭のホルスタイン種泌乳牛を用いて検討した。供試牛は温度18℃相対温度60%の人工環境下で14日間飼養した後，28℃

0.83，Pく0.05）が認められた。暑熱環境下において尿中アラントイン排泄量は減少したが，暑熱期における摂取窒素量に対する微生物態窒素合成量の割合は，18℃における平均63.4%から75.6%へと増加した。また，可消化有機物摂取量あたりの微生物態窒素合成量は，平均20.4から23.0gNに増加した。窒業利用効率あるいは微生物態窒素合成効率は暑熱負荷が長引くにつれて増大する傾向にあった。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001925","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
