Resumo: | An experiment was carried with the objective of evaluating the effect of diet electrolyte balance (DEB) and crude protein (CP) reduction on respiratory rate, cloacal temperature and concentrations of Na+, K+, Cl- and uric acid of broiler chickens. Eight-hundred male Cobb broiler chickens were randomly allocated in 20 boxes, with four treatments and five replicates of 40 birds per experimental unity. The treatments were: T1 - basal diet; T2 - diet adjustment until DEB = 250 mEq kg-1; T3 - diet with reduction of CP and without adjustment of DEB; T4 - diet with reduction of CP and adjustment of DEB to 250 mEq kg-1. The thermal environment was not favorable during the experimental period. The birds that received diets with correction of electrolyte balance showed low values (p < 0.05) of respiratory rate in the phases studied, as well as of cloacal temperature in the phase between 7 and 21 days. Results of cloacal temperature in the total period were not affected (p > 0.05). Reduction of crude protein decreased (p < 0.05) the concentration of sodium in the serum. The use of electrolyte in the concentration of sodium was influenced (p > 0.05) at 42 days. The supplementation with electrolytes improved homeostasis of the broilers in heat stress conditions. |
