Purina NutriTek Technology delivers antioxidants and polyphenols that use immune modulation to remove free radicals that have the potential to cause damage to cells and tissues – allowing her to focus on reaching greater peak milk. The transition period, 21 days before through 21 days after calving, is a challenging time for the dairy cow. Changes in pens, hormones, metabolism, rations and weather add stress, increasing a cow’s energy requirements. At the same time, her feed intake may be compromised-particularly, in the five days before freshening. If a cow is not getting sufficient energy, she may mobilize body reserves to compensate, which can further depress feed intake. Even if there are no obvious metabolic issues, cow health and performance are put to a test during a critical time.
