　　Objective: How to study the effect of selenium-enriched rice bran instead of organic selenium on the growth potential and antioxidant function of young rabbits?

　　Method: Sixty 60-day-old weaned rabbits were randomly divided into normal rice bran group, organic selenium group and selenium-enriched rice bran group, and normal rice bran feed, ordinary rice bran plus organic selenium feed and selenium. Twenty animals in each group, semi-male and semi-male, were fed rich rice bran for a total of 30 days. Have you recorded a total of 30 days of daily feed consumption? Recorded in experiments 0, 5 and 10 respectively. Weigh the experimental rabbits for 15-20-25-30 days, and calculate the feed weight ratio of each group of experimental rabbits. After feeding, the serum of each group of experimental rabbits was collected to detect the content of blood sugar, uric acid, total protein, albumin and globulin. Albumin/globulin ratio and serum glutathione peroxidase (GSH-Px) activity? Superoxide dismutase activity (SOD)? Catalase (CAT) activity and malondialdehyde (MDA) content; collect experimental rabbit liver, spleen and kidney groups, weigh them, calculate the visceral index of each group, and calculate the kidneys. Do you want to test the selenium content?

　　Result: Does the organic selenium group and the selenium-enriched rice bran group increase every day? Feed weight ratio? Organ index? The selenium content in the kidneys and the above blood biochemical indicators are not significantly different from those in the normal rice bran group (P\→ 0.05), but what are the GSH-Px and SOD activities of the selenium-rich rice bran group? The activities of GSH-Px and CAT in the organic selenium group were significantly higher than those in the normal rice bran group (P\u003c0.05), while the MDA content of the two groups were both in the normal rice bran group (P\u003c0.05). The antioxidant capacity of rice bran group and organic selenium group is equivalent, their selenium content is significantly lower, and they are rich in selenium.

　　Conclusion: Like organic selenium, can selenium-rich rice bran promote the growth and antioxidant function of young rabbits, and replace organic selenium as a source of selenium in young rabbit feed?
