Ten captive dingoes were injected with radioactive NaC1 and the turnover of radio—sodium was compared with the measured intake of sodium in the diet, which consisted of rabbit carcasses. A close correlation was established between food intake and ( 22)Na turnover (r = .95). The possible uses of the ( 22)Na turnover technique in measuring food intake in free—living animals are discussed.
