Prepared by the method "ammonia-free water." The concentration of ammonium Bi Nanhai lower surface waters collected about 50nmol / L. 所制备的"无氨海水"去除了原海水中的铵氮,盐度的变化亦可忽略,pH仅略有升高。 The prepared "ammonia-free water." In addition to the ammonium nitrogen atom to ...
Four ruminally fistulated Finnish Ayrshire cows were used to study the effects of different protein supplements on concentration and flow of soluble non-ammonia N (SNAN) into the omasum. The treatments in a 4 · 4 Latin square design were a basal diet of grass silage and barley and the ba...
