Laying hens were selected at random and placed in individual cages in a commercial type layer shed. One hundred hens received town water and one hundred received town water supplemented with 2 g NaCl/L. Half the hens on each water treatment were inseminated every 7 days with mixed semen collected from six cockerels of a commercial table egg strain maintained on town water. The remaining hens were inseminated with semen from six cockerels receiving town water supplemented with 2 g NaCl/L. Eggs were collected and stored at 12 C over a 7-day period before eggs with defective shells were identified and removed. All remaining eggs were incubated and candled at 7 and 18 days of incubation to detect infertile eggs and embryonic deaths. Data from six consecutive hatches were analyzed. The incidence of eggs with defective shells doubled in hens receiving the saline drinking water. These hens had a significantly (twofold) higher incidence of embryonic deaths and a significantly lower (13%) hatchability of fertile eggs. For every 100 eggs laid the numbers of settable eggs and chicks hatched were significantly reduced in hens receiving the saline drinking water. The saline water reduced the numbers hatched by 20% for every 100 eggs laid. The water treatment given to the cockerels had little effect on reproductive performance.
随机挑选蛋鸡，将其置于商业型蛋鸡舍的单笼中。100只母鸡饮用城镇自来水，100只母鸡饮用添加了2克氯化钠/升的城镇自来水。每种水处理方式下的母鸡中有一半每隔7天用从饮用城镇自来水的商业蛋用品种的6只公鸡采集的混合精液进行人工授精。其余母鸡用饮用添加了2克氯化钠/升的城镇自来水的6只公鸡的精液进行人工授精。收集鸡蛋并在12℃下保存7天，然后识别并剔除有缺陷蛋壳的鸡蛋。将所有剩余的鸡蛋进行孵化，并在孵化的第7天和第18天进行照蛋，以检测未受精蛋和胚胎死亡情况。对连续6批孵化的数据进行了分析。饮用含盐饮用水的母鸡中，有缺陷蛋壳的鸡蛋发生率增加了一倍。这些母鸡的胚胎死亡率显著（两倍）更高，可育蛋的孵化率显著更低（13%）。对于每100个产下的鸡蛋，饮用含盐饮用水的母鸡中可孵化鸡蛋和孵出小鸡的数量显著减少。每产下100个鸡蛋，含盐饮用水使孵出数量减少20%。给公鸡的水处理对繁殖性能影响不大。
