Nine generations of goats receiving 2.5 to 6.5 mg Al/kg feed dry matter (DM) developed significantly increased mortality, impaired success of first insemination, an increased rate of abortions and, in the fourth generation, a distinct weakness of the hindlegs. Aluminum-poor nutrition led to significant variations of Al contents of aorta, spleen and bones. This effect of aluminum-poor nutrition was also evident in chickens. The normative requirement of animals is < 10 mg Al/kg diet DM. A potential daily normative aluminum requirement - if it should exist - is < 2000 μg, on the average of a week. The aluminum requirement of animals and man is satisfied by the natural aluminum offer.

Cadmium-poor nutrition (< 15 μg Cd/kg feed dry matter (DM)) did not affect feed intake and growth rate, while it affected reproduction performance. Intrauterinally cadmium-depleted kids were often phlegmatic, too lazy to eat and drink, and died of muscle weakness. With oral application of the control feed (300 μg Cd/kg DM), they slowly regained their mobility. Feeding them 65 μg Cd/kg feed DM prevented myasthenia. The normative cadmium requirement of goats (and animals in general) amounts to < 20 μg/kg diet DM. The daily requirement of humans might be < 3 μg.
