Two experiments were performed with broiler chicks housed in battery brooders to ascertain their response to low levels of dietary sodium, supplied by either sodium chloride or sodium bicarbonate, and to compare the utilization of sodium from the materials. In each experiment, three replicate pens containing seven female day-old chicks were offered each treatment for a 21-day feeding period. Sodium chloride levels of 0, .05, .10, .15, or .20% were a portion of the dietary treatments. Additional groups received the same basal supplemented with .072, .144, or .216% sodium bicarbonate in the first experiment and .072 or .144% during the second, in order to provide sodium levels comparable to those resulting from .05, .10, or .15% sodium chloride. Group body weights, water consumption, feed consumption, and manure moisture served as evaluation criteria. As the level of sodium chloride was increased, body weights, feed and water intake, and manure moisture also increased. In neither experiment were there significant differences between the body weights of birds receiving sodium bicarbonate and those resulting from feeding comparable levels of sodium from sodium chloride. Average daily feed and sodium intake also did not differ statistically between groups receiving comparable sodium from either source. Water intake tended to be somewhat higher for sodium bicarbonate treatments and was significantly so for the .144% sodium bicarbonate treatment of the second experiment. Manure moisture was somewhat variable and did not differ statistically between sources at the same sodium level. It is concluded that the sodium from sodium bicarbonate was utilized in a manner comparable to that from sodium chloride.
进行了两项实验，将肉鸡雏鸡饲养在层叠式育雏器中，以确定它们对由氯化钠或碳酸氢钠提供的低水平日粮钠的反应，并比较这两种物质中钠的利用率。在每项实验中，将三只装有七只一日龄雌性雏鸡的重复栏分别给予每种处理，为期21天的饲养期。日粮处理的一部分是氯化钠水平为0、0.05%、0.10%、0.15%或0.20%。在第一个实验中，另外几组接受相同的基础日粮，并添加0.072%、0.144%或0.216%的碳酸氢钠，在第二个实验中添加0.072%或0.144%，以便提供与0.05%、0.10%或0.15%氯化钠产生的钠水平相当的钠水平。鸡群体重、饮水量、采食量和粪便湿度作为评估标准。随着氯化钠水平的增加，体重、采食量和饮水量以及粪便湿度也增加。在两项实验中，接受碳酸氢钠的鸡的体重与摄入相当水平氯化钠钠的鸡的体重之间均无显著差异。接受来自任一来源的相当钠水平的组之间，平均每日采食量和钠摄入量在统计学上也没有差异。碳酸氢钠处理的饮水量往往略高，在第二个实验中，0.144%碳酸氢钠处理的饮水量显著更高。粪便湿度有些变化，在相同钠水平下，不同来源之间在统计学上没有差异。得出的结论是，碳酸氢钠中的钠的利用方式与氯化钠中的钠相当。
