An experiment is reported in which the effects of giving copper sulphate-supplemented diets and control unsupplemented pair-fed diets to laying hens were compared. 2. The level of food intake significantly adversely affected mean body-weight, egg number, egg weight, liver, kidney, oviduct and ovary weights. Gizzard weight/kg body-weight was significantly increased both with decreasing levels of food intake and increased CuSO4 supplementation. 3. There was evidence of a depressing effect of CuSO4 per se on egg production and possibly on oviduct and ovary weight. 4. Liver lipid concentration was significantly decreased with decreasing levels of food intake and the results also suggest a depressing effect of CuSO4. 5. The Cu concentrations and total contents in liver and kidneys were significantly increased by dietary added CuSO4. Liver and kidney Zn and Fe concentrations were increased with decreasing levels of food intake rather than by CuSO4 addition.

本报告了一项实验，比较了给蛋鸡投喂补充硫酸铜的日粮和不补充的对照配对饲喂日粮的效果。2. 采食量水平对平均体重、产蛋数、蛋重、肝脏、肾脏、输卵管和卵巢重量有显著的不利影响。随着采食量水平的降低和硫酸铜添加量的增加，每千克体重的肌胃重量显著增加。3. 有证据表明硫酸铜本身对产蛋量有抑制作用，可能对输卵管和卵巢重量也有抑制作用。4. 随着采食量水平的降低，肝脏脂质浓度显著降低，结果还表明硫酸铜有抑制作用。5. 日粮中添加硫酸铜显著提高了肝脏和肾脏中的铜浓度和总含量。肝脏和肾脏中的锌和铁浓度随着采食量水平的降低而增加，而不是通过添加硫酸铜增加。
