Synopsis
Purified diets, containing spray‐dried egg albumen powder as the source of protein, caused cardiovascular symptoms, reminiscent of the “oedema syndrome “, resulting in high mortality when fed to turkey poults from 1 d of age. This was found to be due to the amount of sodium contributed by the albumen to the diets. Use of a reprecipitated albumen of low sodium content produced satisfactory growth and low mortality.
