I measure the blood every sevendays, thats means on day 0, 7, 14 etc. The broiler is the Ross 308. The potassium level is every week dropping lower, but i have no explanation for this fenomen, perhaps you have an explanation?
Hi sorry I have no experience with non humans.. Anyhow, technically (if I understood) you measure the potassium level in blood detained for the whole period 0 7 14 etc.. in what conditions? t°, humidity,.. Is it separated from the whole blood? the tubes are closed? .. at 4°C the potassium as other analytes is not stable and decrease (Na/K pomp)
