Why did you decide to use PerformaNat Calcium Bolus?
“On the recommendation of the RinderAllianz sales representative, I spoke to Dr. Rühle, who introduced me to the bolus: a calcium bolus that also contains active plant ingredients that influence calcium absorption. Since we had so many problems with milk fever during that time, I wanted to try something new.”
How do you use the PerformaNat Calcium Bolus?
“We enter the bolus 4 times as recommended. All cows from the 2nd lactation on get the milk fever prophylaxis, the first entry 4-12h before calving is the most important. When the cow udders swell, they get the first input of bolus – then they start well into lactation. The next one is right after calving, when we first go to the calf and milk colostrum. We give the last boluses 12-24h and 36-48h after calving.”
And what happened then?
“I was really impressed – it worked from one day to the next. Even our old ladies started the lactation well. We barely have any down-lying cows and also the cows with shaky gaits and cold ears have become much rarer. With the 4 inputs the cows are optimally supplied.”
What convinced you most about the PerformaNat Calcium Bolus?
“The bolus is very unbreakable and smells pleasant. Others taste bitter, our cows don’t like that, but with PerformaNat Bolus it’s different. Since we have been using the bolus, we have had hardly any down-lying cows. And if there is one, it usually only needs one infusion to get going again. In the past we often had to give 2-3 infusions, lift the cow for milking and it often took days until she was fit again. We don’t have this amount of work anymore. So I like to invest the time in the bolus inputs.”
