为了验证锌对婴幼儿生长发育的影响，用不同含锌量的人工半合成词料，饲养生长中的大鼠。对其生长、发育过程进行了详细的观察。结果锌严重缺乏组大鼠平均摄食总量仅为对照组的４３％左右，不同程度缺锌组大鼠平均体重增加量与饲料含锌量间呈显著正相关（ｒ＝０．９９６），严重缺锌组食物转化率为３．１９７，补锌的营养生理作用是显著提高了大鼠的食物利用率，但饲料含锌量提高２５倍，其食物转化率的改变却非常小。结合多项血液学及有关生化参数的分析测试结果，讨论了锌缺乏对大鼠生长的影响和缺锌诊断的综合评价方法。
In order to verify the impact of zinc on the growth and development of infants and young children, the growing rats were bred with artificial semi-synthetic corpus containing different amounts of zinc. The growth and development of a detailed observation. Results The average dietary intake of rats with severe zinc deficiency was only 43% of that of the control rats. The average weight gain of rats in different degrees of zinc deficiency was positively correlated with the dietary zinc (r = 0.996), severe The food conversion rate of zinc deficiency group was 3.197. The nutritional and physiological effects of zinc supplementation significantly increased the food utilization rate of rats, but the zinc content of feed increased 25 times and the change of food conversion rate was very small. Combined with a number of hematological and biochemical parameters of the test results to discuss the impact of zinc deficiency on rat growth and zinc deficiency diagnosis of a comprehensive evaluation.
