ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE May 2025 index was clearly decreased again. Concerning the heifers, the AI index was improved even more significantly. In parallel with the fertility parameters, the urogenital health parameters monitored by the scanning technician were similarly improved. After the trial period, the farmer kept using the product at a daily dosage of 20 g per cow and day. SUMMARY & CONCLUSION The different types of field trials introduced here demonstrate that mycotoxins can have significant impacts on the health and productivity of dairy cows under field conditions. Particularly in the presence of DON, a reduced milk yield and milk fat were observed. Increased SCC is also one of the frequently observed problems. Apart from this, reduced fertility, especially promoted by ZEA, can be another costly consequence. Efficient toxin binders, such as the product applied in these field trials, are specific strategies against this environmental stress factor. They safely neutralize a relevant negative component in the environment of dairy cows and thus not only preserve health and performance, but also the profitability of dairy farms. References 1.
