摘　　要： 35周龄108只依沙蛋鸡随机分为3组,每组36只,第1组做对照仅喂基础日粮,第2、3组分别在基础日粮中添加等量的Ge-132粉剂和水溶液,检测蛋中锗和胆固醇含量,称取全蛋、蛋白、蛋黄、蛋壳重量,统计各组产蛋量并进行临床观察。结果表明:1 试验期间各组鸡的精神状态良好,组间产量无显著差异(P>0.05);2 第2、3组鸡蛋中均有明显的锗富集,每枚蛋的含锗量波动在26.16±48.91μg之间,惟两组蛋中锗含量,水溶剂组明显高于粉剂组,差异显著(P<0.05);3 喂锗两组蛋中胆固醇含量明显降低(P<0.05),但2、3组间差异不显著。试验进一步证实:饲料中添加适量的Ge-132可以生产出富锗低胆固醇的鸡蛋,采用水溶液添加Ge-132为佳,易被鸡体吸收和蛋中生物富集。 One hundred and eitht layers aged 35 weeks were randomlydivided into three groups, 36 per group. The hens of group Ⅱ and Ⅲ werefed the diets containing the equal dose of ge -132 with powdery andaqueous solution respectively. The hens of group Ⅰ were only given thebasal diets. Eight eggs were randomly collected ay the fifth, tenth, fifteenth and twentieth days after oral administration of Ge -132. Germanium levels and egg-yolk chlesterol contents and weight of wholeegg,albumen,yolk and egg shell were examined. The laying rate andhealthy status were analyzed during the experiment, the experimentalresults showed as follows.1.The healthy status of every group layershad no any abnormal phenomena in the period of experiment. There were nosingnificant differences of laying rate among groups.2. There weresignificant germanium enrichments in eggs of group Ⅱ and Ⅲ . The fluctuation ranges were from26.16 to 48.91μg.The germanium contents of aqueous dosage group were more significant than those of powdery group(P<0.05).3. The egg-yolk cholesterol levels of group Ⅰ were higher than thoseof group Ⅱ and Ⅲ . There were no differences of egg chol esterol levels between group Ⅱ and Ⅲ . The research first demonstrated thatgermanium-riched and low-cholesterol eggs were produced by adding theproper dose of Ge -132 as a kind of feed additive and Ge-132 of aqueousdosage could be easy to absorb and to richen in the eggs.
