To ensure an optimal growth is crucial in raising healthy dogs, especially in large and giant breeds. Dogs with a moderate growth velocity tend to have lesser problems with developmental orthopaedic diseases than those with forced or maximum weight gain. In this study, the energy needs of growing dogs from two different breeds (Beagles as a medium-size breed and Foxhound crossbreds as a large-size breed) to ensure a growth development as recommended by the National Research Council (NRC) were determined at the age of 6-28 weeks. After weaning at the age of 6 weeks, the food rations sufficient to meet the energy requirements of each individual puppy were adjusted every other day according to growth level, guaranteeing a development consistent with the recommended weight curve for the respective breed size. The food and therefore energy intake of the puppies was registered daily; it ranged from 0.72 to 2.34 times the maintenance requirements with little effect of age. During the whole period, however, there was a consistent breed difference: Foxhound-Boxer-Ingelheim Labrador crossbreds (FBIs) had higher energy intakes expressed as multiples of maintenance than Beagles, suggesting that during the major period of growth, the energy requirement is not a function of age. Adult Beagles and FBIs showed similar differences in energy requirements as already during growth as shown in this study. This indicates that breed differences in energy requirements have already to be taken into account during growth. On the other hand, the results showed clearly lower energy needs for growth in these two different breeds than recommended in the NRC.
确保犬只健康生长至关重要，尤其是对于大型和巨型犬种。生长速度适中的犬只比生长过快或过快增加体重的犬更容易出现发育性骨科疾病。本研究旨在确定两种不同品种（比格犬为中型品种，猎狐犬杂交犬为大型品种）的幼犬在 6-28 周龄时生长所需的能量，以确保其生长发育符合国家研究委员会（NRC）的建议。6 周龄断奶后，根据生长水平每隔一天调整满足每个幼犬个体能量需求的食物配给量，以确保其与各自品种大小的推荐体重曲线相一致的发育。幼犬的食物和因此的能量摄入量每天都会被记录；其摄入量范围为维持需要量的 0.72 至 2.34 倍，受年龄影响较小。然而，在整个研究期间，一直存在着明显的品种差异：猎狐犬-拳师犬-因格尔斯海姆拉布拉多犬杂交犬（FBIs）的能量摄入量作为维持需要量的倍数高于比格犬，这表明在主要生长阶段，能量需求不是年龄的函数。成年比格犬和 FBI 在能量需求方面表现出的差异与本研究中生长阶段相似。这表明，在生长期间，必须考虑犬种间能量需求的差异。另一方面，研究结果清楚地表明，这两种不同品种的生长所需能量明显低于 NRC 建议的能量。
