A concentrated extract of tansy fermented with Lactobacillus and Lactiplantibacillus bacteria offers a convenient and effective alternative to traditional tansy extract. This is a practical solution that saves time and avoids the difficulties involved in making such a preparation yourself. Making the extract yourself requires finding a sufficiently large quantity of tansy and picking it, which takes quite a long time. BROS NATURAL Tansy Silage is a product that is almost ready to use (it only needs to be diluted) and is very convenient to use.
