Abstract :
Up to now continuous long-term monitoring of ruminal pH in dairy cows, which is necessary to detect and to treat subacute rumen acidosis (SARA) effectively, is not possible due to the lack of transmitters that meet all the requirements of this application. Therefore, an autonomous pH probe with data storage was developed and investigated in laboratory and in a fistulated cow. The pH drift was lower than ΔpH < 0.2 during 14 days of measurement in the rumen.
