The response of 315 day-old quail broiler chicks to seven levels of dietary lactose at 0, 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0 percent was evaluated by conducting a feeding trial of from 0-35 days of age. Each diet was offered to 3 replicate groups of 15 chicks. Results indicated that supplemental lactose increased the body weight gain and feed intake with better FCR as compared to control diet, although they were not found to be statistically significant. Numerically better body weight gain & feed efficiency was recorded in diet supplemented with 3% lactose. Carcass evaluation studies also revealed non-significant differences among all the groups with respect to dressing percentage, eviscerated percentage, heart, gizzard, and bursa and spleen weight percentages. However, the percent caecum weight increased significantly (P< 0.05) with lactose levels of 3.0, 4.0 and 5.0% while the percent liver weight increased with 4.0 and 5.0% lactose.
