The objectives of this investigations were to: (1) determine the quantitative dietary chloride requirement of starting turkeys, 0-4 weeks of age, and (2) to study the effects of chloride deficiency. Although there is a close relationship between chloride and sodium in certain physiological processes, the chloride ion has functions which are essentially independent of the sodium ion. Specific functions of the chloride ion to be discussed in this thesis include: (1) regulation of osmotic pressure, (2) involvement in the chloride shifts reaction, (3) the major anion of gastric juice and (2) an important role in acid-base balance.

Four experiments of 28 days duration were conducted to determine the dietary chloride requirement of starting turkeys and to study the effect of chloride deficiency. A basal diet composed largely of dextrose (cerelose) and isolated soybean protein was utilized. The chloride content of this diet was .005 percent as determined by chemical analysis. Distilled water and experimental diets were supplied ad libitum to poults in all experiments.

Maximum body weight gain was obtained with .145 percent of dietary chloride. Therefore, the minimum dietary requirement for growth was greater than .125 percent but apparently no more than .145 percent.
