To examine the relative nutritive value of sorghum to corn for laying hens, 20 week old 240 Single Comb White Leghorn (SCWL) starting layer were employed and randomly assigned to each of 5 experimental diets which were prepared by the substitution of sorghum for corn portion (60%) of the basal diet with various ratios, i.e., 60% corn (control), 45% corn + 15% sorghum, 30% corn + 30% sorghum, 15% corn + 45% sorghum and 60% sorghum. Five groups of starting layers employed in this study have been pretreated in the same manner during thelaying period and the growing period. Hens were fed phase 1 (21-42 weeks) and phase 2 diet (43-62 weeks) during the laying period, and laying performance were examined
