Rats weaned early at 13 days of age exhibited at 10% lower growth within 6 weeks when Mn supply was deficient compared to control animals (P is less than 0.005). While the reduction of the dietary Mn content from 50 to 6 ppm did not yet affect growth, the animals already showed a 60% lower arginase activity at this median level of Mn supply. The values of the depleted animals (0.7 ppm Mn) had fallen by 71% compared to the control group. Therefore, the arginase values may be applied to differentiate between suboptimum and optimum Mn supply.
与对照动物相比，13日龄早期断奶的大鼠在锰供应不足时，6周内生长速度降低10%（P小于0.005）。虽然将日粮锰含量从50 ppm降至6 ppm尚未影响生长，但在这个锰供应的中间水平，动物的精氨酸酶活性已经降低了60%。与对照组相比，锰缺乏动物（0.7 ppm锰）的精氨酸酶活性值下降了71%。因此，精氨酸酶活性值可用于区分次优和最佳锰供应情况。
