The aim of this study was to determine whether methionine, lysine, choline, or sulfur supplementation ameliorates adverse effects on laying performance and egg quality resulting from inclusion of a high level of common vetch seed (CVS) into diets of hens. Lohman layers, 30 wk of age as 6 replicate cages of 4 hens, were allocated randomly to receive basal diets containing either 12% soybean meal (13) or 22% CVS (BCVS) and diets BCVS plus 0.57% methionine, 0.66% lysine, 0.47% choline, or 0.05% sulfur for 98 d. Feed intake (FI) and egg production (EP) were recorded daily; egg weight (EW) was measured biweekly; and BW was measured monthly. A sample of 12 eggs from each experimental group was collected every month to evaluate egg quality.
