Abstract

The purpose of this study was to know the potency of 1.5% KCl, 0.5% NaHCO3 and combination of both electrolytes supplementation toward the changes of broiler’s spleen exposed to chronic heat stress. 30 broilers with 3 weeks ages divided into 5 different groups (n=6) and separated into two different chamber (A and B). One group (control/P0) was caged at low temperature (21-23ºC) in chamber A, while the others (P1; P2; P3; P4) were caged at high temperature (37ºC) in chamber B. Group P1 administrated only with water, while group P2, P3 and P4 administrated respectively with 1.5% KCl, 0.5% NaHCO3 and the combination of both. After fifteen days of treatment, all broilers were sacrificed for spleen macropathology and histopathology examination. Collected data for spleen weight and white pulp diameter was analysed with Anova test. This study showed that supplementation of 1.5% KCl, 0.5% NaHCO3, and combination of both failed to inhibit the changes of spleen pathology on chronic heat-stressed broiler.
