Tóm tắt

1. In Expt 1, the effects on laying hens of diets supplemented with zinc oxide providing up to 20 gadded 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.
