Study on Enriched Germanium Milk
Twelve Holstein cows were randomly divided into three groups (i.e.,control group Ⅰ,inorganic germanium group Ⅱ and organic group Ⅲ),which were treated with Ⅰ(CK) ,Ⅱ (GeO 2) and Ⅲ (Ge 132),to probe the feasibility of biologically enriched germanium milk by using different germanium materials.The result showed that after thirty days germanium concentration in milk of the tested groups reached a high level. The germanium contents of Ⅱ and Ⅲ groups were 3 91 and 5 11 times as high as that of contrast group Ⅰ(P0 01)respectively;germanium concentration in milk of Ge 132 group were from 15 17% to 40 98% more than that of GeO 2 group(P0 05),and 30 76% in the high level(P0 05).It was suggested that it was likely to gain enriched germanium milk by way of feeding cows with germanium material.The biotransformation efficiency of organic germanium material was siganificantly better than that of inorganic germanium material.
