The sodium requirements of beef calves for growth

Abstract
SUMMARY Thirty-two beef calves (mean body weight 79 kg) were given a ration which depleted their body reserves of Na as was evidenced by a narrow Na to K ratio in the parotid saliva. Eight calves were then assigned to each of the following four treatments: low Na basal ration alone, basal ration plus either 1·09, 2·19 or 3·28 g Na/calf/day as bicarbonate.
