Fattening bulls were given alkali-treated straw during 5--7 months. The daily intake of Na was 10 times greater than the requirement. The daily increase in body-weight was very high (1571--1898 g per day). No negative influence on animal health was recorded. The size of the kidneys did not increase, nor were there any histopathological abnormalities which could be attributed to the overfeeding with Na.
育肥牛在5至7个月期间被给予碱处理过的秸秆。钠的每日摄入量比需求量高10倍。体重的每日增加量非常高（每天1571至1898克）。未记录到对动物健康的负面影响。肾脏大小没有增加，也没有任何可归因于过量摄入钠的组织病理学异常。
