Abstract

From 36 to 43 weeks of age 210 White Leghorn laying hens were used to study the relationship of plasma calcium and phosphorus concentrations to egg-shell quality when saline drinking water was given. 2. Seven experimental treatments in which different amounts of sodium chloride were supplied by the food and/or the drinking water were compared. 3. Increasing salt intake through the drinking water or the food reduced shell thickness and shell calcium, and increased the numbers of damaged eggs. Sodium chloride given in the drinking water was more effective in reducing shell quality and increasing plasma calcium and phosphorus than sodium chloride given in the food.

摘要

在36至43周龄时，使用210只白来航蛋鸡来研究饮用盐水时血浆钙和磷浓度与蛋壳质量之间的关系。2. 比较了七种实验处理，其中通过食物和/或饮用水提供不同量的氯化钠。3. 通过饮用水或食物增加盐摄入量会降低蛋壳厚度和蛋壳钙含量，并增加破损蛋的数量。与食物中添加氯化钠相比，饮用水中添加氯化钠在降低蛋壳质量和增加血浆钙和磷方面更有效。
