The effects of dietary supplementation on milk output and maternal body composition were investigated in the lactating rat. The supplement was a cooked homogeneous mixture of eggs and maize oil, and had the same protein-energy: total energy value as the control diet. During 2-12 d post partum rats were fed ad lib., either on the control diet alone or on the control diet plus the supplement. Measurements were made of milk output using an isotope-dilution technique, milk composition, and dam and litter body-composition changes. Compared with the dams receiving only the control diet, dams provided with the supplement consumed 19.7% more energy and protein and produced 31.2% more milk and mobilized less body fat. By 12 d of age, pups in litters of dams receiving the supplement were significantly heavier than those in litters of dams receiving the control diet only, and they contained more protein and more fat. It is concluded that dietary supplementation of lactating rats can enhance lactational performance.
在泌乳大鼠中研究了膳食补充剂对产奶量和母体身体组成的影响。补充剂是鸡蛋和玉米油的熟制均匀混合物，其蛋白质能量与总能量的比值与对照饮食相同。在产后2至12天，大鼠自由采食，要么只喂对照饮食，要么喂对照饮食加补充剂。使用同位素稀释技术测量产奶量、乳汁成分以及母鼠和幼崽身体组成的变化。与只接受对照饮食的母鼠相比，接受补充剂的母鼠消耗的能量和蛋白质多19.7%，产奶量多31.2%，且动员的身体脂肪更少。到12日龄时，接受补充剂的母鼠所产幼崽比只接受对照饮食的母鼠所产幼崽明显更重，且含有更多的蛋白质和脂肪。得出的结论是，对泌乳大鼠进行膳食补充可以提高泌乳性能。
