Sažetak
The purpose of the study was to examine the effect of 24-hour heat stress on blood acid-base balance parameters and mineral content in guinea fowls when drinking water treated with magnetic field was used. The maximum environmental temperature at the end of the present experiment was 32oC. The relative humidity was maintained at 55% (±2). Blood samples were collected from birds three times: in the 1st, 12th and 24th hour of stress. Exposure to heat
stress significantly increased blood bicarbonate ion concentration (HCO3 -), content of buffer alkali (BB) and decreased shortage of alkali (BE) but only in the 12th hour of stress. In the level of oxygen pressure (pO2) and percentage of oxygen content (O2sat) in the 12th and 24th hour of the experiment statistically high significant decrease occurred. In consequence of high environmental temperature the statistically significant decrease of sodium was found. No changes in the level of potassium and chlorine ions in guinea fowls watered magnetized water occurred.
