Results of Ketotop trial in China
Protocol for Ketotop Bolus trial
1. Select two groups of cattle with similar parity, age, physical health, and feed
2. The first dosing, 10 days before calving, one white and one red bolus
3. The second dosing, immediately after calving, one white and one red
Observation index
The oxtail blood was collected to determine the BHBA (β-hydroxybutyrate) in the blood of all cows in the two groups:on e week after calving, two weeks after calving, three weeks after calving, four weeks after calving.
Judgment criteria BHBA concentration in blood
<1.2mmol/L: normal
1.2-3.0mmol/L: subclinical ketosis
>3.0mmol/L: clinical ketosis
Location: chinese dairy farm
Time: October 2021
Results
In the control group, 2 of the 30 cows were eliminated. 5 cows developped subclinical ketosis during one or two of the test moments. This accounted for 17,9 % (5/28 cows). There was no clinical ketosis. The BHBA in the blood of other cattle was normal.
Conclusion
The lack of clinical ketosis in both groups shows the great management practises inside this Chinese dairy farm. There was however a clear impact of Ketotop on the occurance of subclinical ketosis. We can argue that farms that are impacted with clinical ketsosis would benefit greatly from ketotop.

Ketosis in cattle: costs, risks, and Ketotop's four lines of defense
Ketosis in dairy cows harms health and reduces profits with costs ranging up to €709 per case. Resco's Ketotop bolus helps prevent ketosis with liver support, herbal extracts, rumen boosters, and energy supply for healthier herds.

Vitamins and trace elements during the dry period
When we talk about the dry period, we don’t mean cutting out alcohol during the increasingly popular “Dry January”. We mean the period between the last milking and the next calving, during which the nutrient requirements are reduced. However, this doesn’t mean that these cows should be neglected.
