Reduced Inflammation: Heat stress typically triggers an inflammatory response, with increased levels of acute phase proteins (APP) such as haptoglobin (Hp). The study found that cows supplemented with the IntelliBond Z had a more controlled inflammatory response, with lower levels of Hp during heat stress recovery (Figure 2) 3. Enhanced metabolic health: The study also showed that supplementing cows with the IntelliBond Z mineral led to better metabolic outcomes. Compared to the control group, animals receiving the IntelliBond source had lower levels of nonesterified fatty acids (NEFA) and beta-hydroxybutyrate (BHB), indicating a less catabolic state and improved energy balance.1 4. Increased dry matter intake (DMI): During the recovery period, cows receiving IntelliBond Z showed a significant increase in DMI compared to the control group (Figure 3). This suggests that the IntelliBond Z helps cows regain their appetite and nutritional intake more effectively after heat stress. Figure 3.
