Effect of feeding rice grown on highly saline soils treated with zinc salts on the vitamin status of the body

The influence of the feeding of August rats with rice grown in highly saline soils, treated with different doses of industrial zinc salts, on the body providing with riboflavin, ascorbic acid, vitamins A, E and PP was studied. The meliorative-active matter was used in doses of 40 and 80 kg/hectare. The grain of the same sort grown under similar conditions but without the meliorative agent, served as control. It has been established that the feeding of the rats with rice grown in soils, treated with high doses of industrial zinc salts, produces unfavourable effect on the animals' body inducing serious disorders in vitamin metabolism.
