Amaranthus leaf meal (ALM) was included in layer diets at 0, 2.5, 5, 7.5 and 10 per cent levels on iso-proteinic and iso-caloric basis. Sixty layers of 45 weeks old were randomly grouped to contain 4 birds in each replicate and 3 replicates were allotted for each treatment and the experiment was carried out for total period of 12 weeks. During this period, the birds were fed on control diet for 3 weeks before and 3 weeks after the experimental period i.e. 6 weeks. The egg cholesterol levels in both pre and post-experimental periods were also estimated. The feed intake, egg production, feed efficiency, body weight, egg weight and egg quality were not affected in ALM fed layers compared to control. However, inclusion of ALM at different levels in layers diets have significantly (P < 0.01) decreased the egg cholesterol and improved the yolk color. But a significant increase in cholesterol level during post-experimental period (birds were fed on control diets). Based on the egg cholesterol and economic traits, the ALM could be incorporated up to 75% in layers diets without affecting their performance
