The objective of this study was to investigate the effects on laying performance, egg quality traits, color, and composition of supplementing a white corn-based diet with leaf flour. Three hundred 32-week-old hens were distributed to 30 pens of 10 hens each and allocated to six dietary treatments (five replicates per treatment) for 13 weeks. Two control groups of 50 hens received one of either diet Y, based on yellow corn, or diet W, based on white corn. The other groups received a diet based on white corn supplemented with leaf flour at 2.5%, 5%, 7.5%, or 10% (diet D). Diet D improved laying performance and yolk color at a reduced feed cost per egg but had no effect on cholesterol content. In conclusion, the inclusion of leaf flour, in a white corn-based diet, is effective in lowering feed cost, increasing egg production, and improving yolk color.
本研究的目的是调查用叶粉补充以白玉米为基础的日粮对产蛋性能、蛋品质性状、颜色和组成的影响。300只32周龄母鸡被分配到30个鸡笼中，每个鸡笼10只，并分配到六种日粮处理组（每个处理组五个重复），为期13周。两个对照组各有50只母鸡，分别接受基于黄玉米的日粮Y或基于白玉米的日粮W。其他组接受以白玉米为基础并添加2.5%、5%、7.5%或10%叶粉的日粮（日粮D）。日粮D提高了产蛋性能和蛋黄颜色，同时降低了每枚鸡蛋的饲料成本，但对胆固醇含量没有影响。总之，在以白玉米为基础的日粮中添加叶粉可有效降低饲料成本、提高产蛋量并改善蛋黄颜色。
