Few things are more frustrating than cows that simply no longer get pregnant. Often these are the good, high-performing cows whose offspring one would like to have in the herd. But it is not only the reduced breeding progress that has an impact. Every additional insemination costs money and causes problems in the subsequent lactation. Optimal management and good oestrus monitoring are needed here. Sometimes this is not enough. Here, herbs and medicinal herbs can offer additional valuable support to get cows successfully through the transit phase and back in foal in a timely manner.
