Abstract: This study was conducted to determine the response of laying hens to graded dietary levels of cooked Lablab purpureus beans. Six isonitrogenous diets with similar calorie levels were formulated to contain lablab seed meal at 0.0, 7.5, 15.0, 22.5, 30.0 and 37.5%, respectively. Diet 1, which contained no lablab, served as the control diet. It was a normal groundnut cake-maize based layers ration. Each treatment was replicated three times in a completely randomized design. There were 25 laying hens per replicate. Feed and water were provided ad libitum. The birds were managed under the deep litter system. The experiment lasted for 6 months. There was a significant (p>0.05) decrease in final weight, percent change in body weight, feed intake (g bird-1 day-1), feed efficiency, percent hen-day and hen-housed egg production, percent production at peak, average egg weight (g) and income above feed expenses (x) as the level of lablab beans in the diets increased but feed cost (x/12 eggs), age at 25, 50 and at peak egg production (days) and the Roche Yolk Colour Fan (RYCF) score increased significantly (p<0.05) as dietary level of lablab seeds increased. It was concluded that lablab seed meal can be fed up to 7.5% dietary level in layers ration without any significant (p>0.05) adverse effect on percent hen-day and hen-housed egg production.
