摘要
本文报告对强化奶粉的蛋白质功效比值(PER)、对大鼠体重的增重效应(饲料利用率)和对诱导高血脂症的阻抑效应的测定结果。结果表明,强化奶粉的PER(2.41±0.441)略高于酪蛋白参考标准PER(2.39±0.311);每100g饲料使大鼠增重克数(饲料利用率)为24.1±4.11g,明显高于普通奶粉的13.6±2.16g(P<0.01);对猪油、外源性胆固醇等诱导大鼠血清胆固醇和甘油三脂的形成,具有显著地抑制作用。
Based on the purpose of producing Milk Powder Fortified by Some Nutrients (MPFSN) and its nutri- tional characters, the PER, the effect of MPFSN on increacing the weight of rats feed availablity and its in- hiitory effect on the hyperlipaemia in duced in rats have been observed. As a resrlt, it was found that the PER of the reference casein and MPFSN was 2.39±0. 311 and 2. 41±0. 441 respectively (p<0. 05). The MPESN per 100g increased the weight of rats 24.1 ± 4.41g, but common milk powder only increasefd 17.6 ±2. 16g(p>0.01). The inhibitory effect of MPFEN on hyperlipaemia induced in rat was significantly stronger than that of the common milk powder.
