实验证明，用含锌量为１．７２×１０－６的低锌饲料喂养，不论是年幼或妊娠金黄地鼠，均可发生腹泻、被毛稀疏、易脱落、足趾溃烂，个别还有出血点、生长发育迟缓、体重减轻、饲料效价和血清锌、铜浓度降低。幼鼠对照组体重增长值为４５．２０ｇ，血清锌为３４．４３±４．１３μｍｏｌ／Ｌ。饲料效价为０．１６１０，缺锌组体重增长值仅２０．５２ｇ，血清锌为２１．４２±３．０６μｍｏｌ／Ｌ，饲料效价为０．１３３８，而补锌组食用含锌量为１００×１０－６饲料的幼鼠或妊鼠均无上述缺锌现象，幼鼠体重增长值、血清锌和饲料效价均接近或高于对照组．分别为５５．３３ｇ，３８．４０±６．８９μｍｏｌ／Ｌ，０．１５９１。
Experiments show that with a zinc content of 1.72 × 10-6 low zinc diets feed, whether young or pregnant golden hamster, diarrhea can occur, sparse hair, easy to fall off, toe ulcers, and in some cases Bleeding point, growth retardation, weight loss, feed titer and serum zinc, copper concentration decreased. The weight gain of the control group was 45.20g and the serum zinc was 34.43 ± 4.13μmol / L. Feed titer was 0.1610, body weight gain in zinc-deficient group was only 20.52g, serum zinc was 21.42 ± 3.06μmol / L, feed titer was 0.1338, while zinc content in zinc-supplemented group was 100 × 10-6 diets of young rats or pregnant mice were not zinc deficiency phenomenon, weight gain in young rats, serum zinc and feed titer were close to or higher than the control group. Respectively 55.33g, 38.40 ± 6.89μmol / L, 0.1591.
