Due to stricter legislation and regulations, it is becoming increasingly important to guarantee the health and welfare of dairy cattle and to feed them efficiently. This not only has a direct impact on farm returns, but also influences the resistance of the livestock. Suboptimal resistance can lead to lower production levels and higher maintenance costs. Studies show that 70% of health problems in dairy cattle arise from imbalances in rations, digestion, and feed utilization. Factors such as varying feed quality, ration changes, grazing, climatic influences and increased disease pressure can disrupt this balance. Adequate digestive support, optimal feed utilization and strengthening resistance are crucial to effectively meet these challenges.
