Abstract

The effect of riboflavin supplements of 0, 1, 2, 3, 4 and 8 mg/kg feed to a ration with 0,65 mg native riboflavin was tested in a fattening trial with 360 male day old broilers in 6 groups. The performance data weight gains, feed intake and feed efficiency (kg feed/kg weight gain) were measured. The experiment lasted 5 weeks. Animals with 0 or 1 mg riboflavin supplementation exhibited severe deficiency symptoms. These groups were excluded from the experiment after 11 or 15 days, respectively. The mean average final weights of the other groups were 1750 g, with a daily feed intake of 81 g and 1.65 kg feed consumption/kg weight gain. From these results it is recommended to supplement rations in practical broiler fattening with 3 mg riboflavin/kg feed.
