In the department for calves being fed with fluid feed of a specialised enterprise for calf rearing the daily intake of fluid feed (skim milk improved with milk substitute), concentrated feed and hay of a total of 341 female animals and the daily intake of energy and protein was calculated thereof. The average consumption of nutrients of the 206 healthy calves was compared with some international and national norms for the demand of nutrients. The comparison with some international values of demand and the results of the partial correlation analysis between energy and protein intake and live weight increase showed that the applied nutrition regime (particularly the kind of fluid feed) has resulted in an excessive supply of the calves with proteins and an insufficient supply with energy. This could not be realised from the GDR nutrients norm for the raising of calves published in 1976. Based on theoretical considerations and some recent findings of the science of nutrition we derived values of the protein and energy demand of our own. Subsequently an attempt is made to assess the supply with nutrients for sick calves.
在一家专门的犊牛饲养企业中，负责给犊牛喂流食的部门对341头雌性动物的流食（用代乳品改良的脱脂牛奶）、精饲料和干草的日摄入量进行了计算，并据此算出了能量和蛋白质的日摄入量。将206头健康犊牛的营养平均消耗量与一些国际和国家的营养需求标准进行了比较。与一些国际需求值的比较以及能量和蛋白质摄入量与体重增加之间的偏相关分析结果表明，所采用的营养方案（尤其是流食的种类）导致犊牛蛋白质供应过剩而能量供应不足。这一点在1976年东德发布的犊牛饲养营养标准中并未体现出来。基于理论思考和营养科学的一些最新研究成果，我们得出了自己的蛋白质和能量需求值。随后尝试对患病犊牛的营养供应情况进行评估。
