Abstract
On 25 Swiss and German organic dairy farms all fresh cows (a total of 283 cows between 5 and 50 days in milk) were tested weekly for blood- -hydroxybutyrate (BBHB), 121 exceeded the threshold of 1.0 mmol/l BBHB. A total of 84 cows were randomly assigned to three treatments which were given daily, diluted in 700ml fluid divided to two oral administrations for 4 days: placebo (PL), 240g sodium propionate per day (SP) and 240g sodium propionate combined with an extract of seven herbs (27g drug equivalent). Milk acetone (MAC) and BBHB were observed during the administration period and thereafter, in total for two weeks. A reduction of ketone bodies was measured in all three treatment groups. No significant differences between SP and PL arose regarding the observed parameters. During the first week of observation SP-H showed the lowest MAC and mean values differed significantly from those in group SP (p=0.035) and PL (p{\textless}0.001). After two weeks SP-H showed the largest reduction in BBHB which was by trend different from SP but without differences from PL. Compared to PL or SP, SP-H seemed to have slight advantages in a four days therapy of subclinical ketotic fresh cows.
