Estimation of Ammonium pollution from dairy Simmental cows using precision farming technologies in order to produce health safe food

In order to determine the effect of parity (I, II, III, and IV and season (spring, summer, autumn and winter) on the variability of daily milk yield, milk urea nitrogen and ammonium emission 1, 719, 033 test-day records of dairy Simmental cows were used. The results indicate significant variability in daily milk yield, milk urea nitrogen and ammonium emission due to the animal characteristics (stage and number of lactation) as well as due to season. Furthermore, test day records as a way of precision dairy farming could be used not only for determination of cows’ productivity and detection of feeding disbalance but also for assessing the ammonium pollution from dairy cattle farms.
