【摘要】 基于我国母乳营养调查的结果,模拟研制了适宜中国婴儿生长发育营养需要的配方奶粉,用市场品牌配方奶粉和基础饲料为对照,通过SD大鼠28d的生长实验和昆明小鼠的耐力实验,研究了该配方奶粉对动物生长发育、蛋白质利用率和耐力的影响。生长实验结束时,配方组大鼠的体重增加了184.88g,比基础组和品牌组分别高了179.58g和80.24g;身长增加了11.88cm,比基础组和配方组长了11.00cm和4.31cm;左股骨的重量和骨径也显著优于其它两组;蛋白质的功效比值为3.24,显著优于另外两组;配方组大鼠左股骨中的Ca、Fe、Mg、P含量显著高于基础组,Mg的含量高于品牌组,并且Ca/P接近于2。在耐力实验中,配方组小鼠血清中肝糖原和尿素氮含量分别为3664.02mg/100g肝重和8.28mmol/L,与品牌配方奶粉无显著差异,但显著优于基础组。结果表明,研制的婴儿配方奶粉能够有效地促进大鼠的生长,提高蛋白质利用率,动物各项生理生化指标良好。更多还原

【Abstract】 A new kind of infant formula was designed on the basis of nutrition analysis of breast milk from different regions of China,and subjected to animal experiments. In the development experiment,SD rats of new formula(NF)group grew 11.88cm in body length,11.00cm and 4.31cm longer than famous brand(FB)group and basic diet(BD)group respectively;and body weight of NF group increased 184.88g. The protein efficiency ratio of formula group was 3.24,comparing to 2.81 of BD group and 2.35 of FB group. The concentration of Ca,Fe,Mg,P in left fumer of NF group was significantly higher than BD group,ratio of Ca and P was 2∶1. In the endurance test,the concentration of glycogen and urea nitrogen in serum of the mice receiving new infant milk powder was 3664.02mg/100g liver and 8.28mmol/L respectively. It demonstrated that the growth rate,physiology and biochemical features of rats had been greatly improved by this new infant formula.更多还原
