Two experiments were conducted to determine the effect of choline supplementation on corn-soy-meat-based grower and laying hen diets. Diets contained 2.5% and 3% meat and bone meal in the growing and laying diets, respectively, and on chemical analysis contained 1005 and 1041 ppm of choline respectively. In the first experiment, 1000 ppm of choline were added to the basal growing and laying diets, and in the second experiment the laying diet was supplemented with 550 ppm or 1000 ppm of choline. In both trials, choline supplementation did not increase gains or feed efficiency for pullets from 8 to 20 weeks. However, choline supplementation during the laying period resulted in a statistically significant improvement of egg production and egg size. Supplementation of choline in the growing phase did not affect the laying performance. Laying performance was not improved by 2 micrograms/kg of supplementary vitamin B12 in a 1000 ppm choline supplement diet (78% vs. 76% hen-day production). In the second trial, added levels of choline (0, 500, and 1000 ppm) resulted in egg production from 24 to 64 weeks of 73, 76, and 76% hen-day production, respectively. Egg weights were 59, 61, and 61 g, respectively. This suggests that the total choline requirement of laying hens on a corn-soy-meat diet, and in absence of supplementary methionine, is greater than 1000 ppm but no more than 1500 ppm.
