overloads of amino acid nitrogen could increase stress response, increase urinary nitrogen excretion and deteriorate the respiratory function.
供给氨基酸氮过多则增加应激反应,增加尿氮排出和加重呼吸负担。
there also existed a linear correlation equation between estimated total nitrogen excretion rate and the rates of nitrogen ingestion and assimilation separately, except for the juveniles.
总氮排泄率与氮的摄食率及同化率也分别呈显着正相关,但仔虾例外。
the results reveal that both the oxygen consumption rate and nitrogen excretion rate of juvenile p. olivaceus increase significantly (pbody weight increases;
结果表明,牙鲆幼鱼的耗氧率和氮排泄率均随体重的增加而增加,其差异均达到极显着水平(p<0.01);
antibiotic component adding increased nitrogen excretion from urine, therefore the utilizing efficiency of absorbed n decreased by 9.7%.
添喂抗生素增加尿氮排出,从而降低吸收氮的利用率(9.7% )。
the proportions of food energy lost in nitrogen excretion and channelled into metabolism were not significantly affected by ration.
排泄能和总代谢耗能占摄入食物能的比例不受摄食水平的影响。
