Ascorbic acid (vitamin C) was given to 144-days-old layer chickens mixed with their ration at three concentrations: 30, 60 and 90 p.p.m. for 6 months. Cholesterol levels in blood serum (CS) and egg yolk (CE) were measured every 6 weeks (four periods); there was a marked decrease in CS in most treated birds, especially those receiving the highest concentration of vitamin C. There was also a slight decrease in CE in most treated birds. Thyroidal weight showed a significant increase in most treated groups, especially those receiving the highest concentration of vitamin C.
将抗坏血酸（维生素C）以30、60和90 ppm这三种浓度与144日龄蛋鸡的日粮混合，持续投喂6个月。每6周（共四个阶段）测量血清（CS）和蛋黄（CE）中的胆固醇水平；在大多数接受治疗的鸡中，血清胆固醇水平显著下降，尤其是那些摄入最高浓度维生素C的鸡。大多数接受治疗的鸡的蛋黄胆固醇水平也略有下降。大多数接受治疗的组甲状腺重量显著增加，尤其是那些摄入最高浓度维生素C的组。
