Dynamics of sodium, potassium and acid-base in urine of seasonal calving cows
 FAJMON, Tomáš
In this work, there was observed the influence of feeding an anionic salt on acid-base value in the urine (ABV) and on a level of the calcium in the urine in high yielding dairy cows. This mineral ingredient was tested for two feeding rates: winter - conserved, summer - pasture and was fed in a rate 450 g per a cow and a day. In the winter experimental period there were found no changes in AVB and the effect of Rindavit MF Sauer wasn´t expressed. In the sum-mer experimental period the influence of Rindavit MF Sauer on acid-base balance was fully expressed although the high potassium level in the feed rate. We found statistically significant differences between control and experimental group at observing levels of calcium and the effect of the anionic salt was shown. There was found no case of the milk fever in experimental group cows dduring the whole test. By contrast, there were recorded two cases of the milk fever in the control group cows. At feeding the anionic salt, we didn't find any negative effect on the acid - base balance and the health of the cows.
