The influence of an oral and intramuscular Fe-application on the nutrient (dry matter, energy, protein and iron) and feed intake resp. (skim milk, calf rearing feed and lucerne hay) of calves during their 56-day stay in the weaning range of a rearing farm was investigated. There were significant differences between the test animal groups with regard to nutrient intake; their levels had the following sequence: B (Fe orally) greater than C (Fe i.m.) greater than A (without Fe-supplement). In the calf rearing organised as graded production the effect of iron intervention on nutrient intake probably occurs as a consequence of the reduction of the depression of feed consumption caused by disease. By comparison with the nutrient and feed intake of weaning calves from a different rearing farm one can further conclude that this secondary effect of iron intervention does not only depend on the more or less rapid remedy of the differently marked states of iron deficiency of the calves but also on the other rearing conditions (particularly the drinking regime). It is improbable that the oral ferridextran intervention (200 mg Fe/d) carried out provokes excessive iron supply.
研究了口服和肌肉注射铁制剂对犊牛在饲养场断奶期56天内营养物质（干物质、能量、蛋白质和铁）及采食量（脱脂牛奶、犊牛育成饲料和苜蓿干草）的影响。试验动物组之间在营养物质摄入量方面存在显著差异；其水平顺序如下：B组（口服铁）＞C组（肌肉注射铁）＞A组（不补充铁）。在分级生产组织的犊牛饲养中，铁干预对营养物质摄入的影响可能是由于疾病引起的采食量下降减少所致。与来自不同饲养场的断奶犊牛的营养物质和采食量相比，可以进一步得出结论，铁干预的这种次要影响不仅取决于犊牛不同程度缺铁状态的或多或少快速纠正，还取决于其他饲养条件（特别是饮水制度）。口服葡聚糖铁干预（200毫克铁/天）不太可能导致铁供应过量。
