An experiment was conducted on laying hens for 12 weeks to study the effect of chromium picolinate supplementation on performance of laying hens. A total of 72 laying hens of 40 weeks age were distributed in a completely randomized design into 3 groups each with 2 replicates of 12 layers each. Layers of group I were control while that of group II and III were fed water containing 1,000 and 2,000 ppb chromium as chromium picolinate. Layers were kept under uniform managemental conditions throughout the experimental period. Egg production and egg weight of layers were recorded daily and feed intake was recorded replicate wise at weekly intervals and then feed conservation ratio (FCR) was calculated. The overall results of the study indicated that feed intake was reduced and FCR was improved due to chromium picolinate supplementation.
