In Expt 1, the effects on laying hens of diets supplemented with zinc oxide providing up to 20 g added zinc/kg were compared. In Expt 2 the diets contained up to 6 g added Zn/kg. 2. In both experiments, food intake, body-weight, egg number, and liver, oviduct and ovary weights/kg body-weight were significantly reduced by added ZnO; gizzard weight/kg body-weight was significantly increased. In Expt 2, pancreas weight was significantly reduced by added ZnO. 3. Liver, kidney and pancreatic Zn and iron concentrations were significantly elevated in both experiments. 4. In both experiments, liver, kidneys and pancreatic copper concentrations gave quadratic responses to added ZnO.

在实验1中，比较了添加氧化锌的日粮对蛋鸡的影响，添加量最高可达20克锌/千克。在实验2中，日粮中添加锌的量最高为6克/千克。2. 在两个实验中，添加氧化锌均显著降低了采食量、体重、产蛋数以及肝脏、输卵管和卵巢重量/千克体重；砂囊重量/千克体重显著增加。在实验2中，添加氧化锌使胰腺重量显著降低。3. 在两个实验中，肝脏、肾脏和胰腺中的锌和铁浓度均显著升高。4. 在两个实验中，肝脏、肾脏和胰腺中的铜浓度对添加的氧化锌呈二次反应。
