Abstract:
Ninety rats were divided into 8 groups. Group 1-5 were fed vitamin A free ration and each group was divided into 2 subgroups at the beginning and 12, 23, 36, 43, days after the experiment respectively. Group 6-8 were fed the ration containing 66, 132, and 198?g vitamin A per 100g diet respectively fer 30 days, and each group was also divided into 2 subgroups. The results showed that RBPR% was better than the serum vitamin A content in evaluating vitamin A nutritional status. It was suggested that the vitamin A nutritional status could be graded as follows: deficient(abore 70%)) mar-ginal(60-70%),normal (20-60%), and sufficient (under 20%)by RBPR%.
