Addition of the beta-adrenergic agonist clenbuterol to the diet of steers increased blood flow in portal-drained viscera, liver and tissues of the hindquarters. 2. Uptake of oxygen increased with clenbuterol feeding in hindquarters but not portal-drained viscera or liver. 3. On day 1 of clenbuterol feeding, the principal source of circulating L-lactate switched from portal-drained viscera to hindquarters. 4. Both net release of alpha-amino nitrogen by the portal-drained viscera and net uptake by the hindquarters decreased on day 1 of clenbuterol feeding. Over time of clenbuterol feeding, both release of alpha-amino nitrogen by the portal-drained viscera and uptake by the hindquarters increased to equal or greater than pretreatment values, respectively.

在肉牛的日粮中添加β-肾上腺素能激动剂克伦特罗，可增加门静脉引流内脏、肝脏和后躯组织的血流量。2. 后躯组织中氧气的摄取量随克伦特罗的投喂而增加，但门静脉引流内脏或肝脏中的氧气摄取量未增加。3. 在投喂克伦特罗的第1天，循环L-乳酸的主要来源从门静脉引流内脏转变为后躯组织。4. 在投喂克伦特罗的第1天，门静脉引流内脏α-氨基氮的净释放量和后躯组织的净摄取量均下降。随着克伦特罗投喂时间的延长，门静脉引流内脏α-氨基氮的释放量和后躯组织的摄取量分别增加至等于或大于预处理值。
