	abstract = {In two trials using cattle grazing green pasture, daily supplements of  1x106 IU vitamin A decreased plasma carotenoid (PC) concentration by 43- 58\% over 28-31 days. Neither increasing the dose of vitamin A to 2.5 x 106  IU nor continuing the supplement for 83 days further reduced PC  concentrations. These decreases in PC concentrations were not accompanied  by decreases in carotenoid concentration in the subcutaneous fat or fat  colour. This was possibly because PC concentration was still too high to  allow a loss of carotenoids from the fat depots. },
