Electrolyte changes in the blood plasma of broilers as influenced by cooling during summer
- 35 Downloads
High temperature significantly (P < 0.01) decreased the Na+ and K+ concentrations in the blood plasma of both the sexes of broilers during 4 to 8 weeks of age. Relatively constant levels of these electrolytes were observed during this phase of growth and the sex of the bird had no significant effect on their levels.
Greater broiler weights and higher levels of plasma electrolyte were achieved by the use of cooling systems (which were more effective in the hot dry part of the summer than in the hot humid part).
