The sodium content of natural ingredients such as corn, wheat, and soybean meal is low. Thus, these ingredients can be used to create a base diet that is sodium deficient. To this base diet, various amounts of sodium chloride salt (NaCl) can be added, and other ingredients adjusted slightly to maintain a relatively constant nutrient profile (with the exception of sodium and chloride).

    Below are examples from a popular series of adjusted NaCl diets. Contact us for more information.

    * When added to natural ingredient diets, these water soluble food dyes offer a slight color tint. More intense color can be achieved at higher inclusion rates.

    Ask a nutritionist about additional salt concentrations or color options.

    These diets are grain-based, with no animal derived ingredients, and have a background sodium content of approx. 0.01-0.02% and a background chloride content of approx. 0.06-0.07%. The selected nutrient content of the diets are as follows: approximately 19% protein, 5% fat, 3% crude fiber, 0.86% Ca, 0.64% P, 0.72% K, and 0.15% Mg.

    NaCl adjusted diets are often fed to dahl salt-sensitive/resistant (rapp) inbred rats. These rats are maintained on Teklad traditional diet 7034 (0.12% NaCl) within maximum security production facilities.
