Effect of sodium chloride deficiency on basal metabolism in broiler chickens
Published online by Cambridge University Press: 09 March 2007
Abstract
1. Male broiler chickens were given a sodium chloride-deficient or NaCl-adequate diet from 7 to 21 d of age in Expt I and 28 to 56 d of age in Expt 2.
2. NaCl-deficient chickens had a markedly poorer growth and food conversion efficiency than those given the NaCl-adequate diet.
3. NaCl deficiency was associated with an increase in basal metabolic rate and increases in oxygen consumption, heat production and respiratory quotients were also noted. The glycogen content of chicken livers was also higher.
4. Measurements of acid–base balance were found to be changed in NaCl-deficient chickens. Values for pH and bicarbonate content in blood plasma were lowered.
5. NaCl deficiency increased the packed cell volume and thyroxine level in blood plasma. Sodium and chloride contents in blood were lowered.
6. Results are discussed in relation to the decreased food conversion in NaCl-deficient chickens.
