| The acid-base equilibrium is of vital importance for living organisms. Its shifts affect practically all life processes, thus resulting in decreased milk production, sterility, etc. which may cause economic losses. Strong alcalosis in the dry period raises the risk of milk fever after parturition. Examinations on an organic farm were performed because of cumulative occurrence of milk fever and retained placenta. One total mixed ration with excessive supplementation of minerals was fed to all milking cows. The rest of this ration was fed to the cows during the dry period. Net-acid-base-excretion in urine showed a strong alkalosis especially in the dry cows. After modification in feed man-agement milk fever and retained placenta never occurred during the... |

| Pasture based production systems should feed as much as possible pasture gras on the total year ration. On 5 austrian farms, changing to pasture based milk production, blood and urine samples of cows were examined to detect changes and exposure in metabolism during the year and lactation. Some changes in blood parameters were detected at the beginning of the pasture. Changes of feeding at the beginning of the pasture showed a decrease in phosphorus in serum. Net-acid-base excretion also showed the burden of feeding a minimum or none of concentrate and the decreased fedding of crude fibre at the beginning of the pasture. |
