The egg-laying hens were fed with three levels of cottonseed andrapeseed cake dietary for 300 days. The result showed that there was no signi-ficant difference in the concentration of microelements in the liver between thegroups. The hens fed with three levels of cottonseed cake dietary had significanteffects on liver manganese. The liver manganese of hens fed with low, middleand high cottonseed cake diets was 5.97 ppm, 5.85 ppm and 8.05 ppm respec-tively. The hens fed with three levels of rapeseed cake dietary had significanteffects on liver selenium. The liver selenium of hens fed with low, ...
