How can stress affect animal health and productivity?

• A. It can enhance immune function
• B. It can lead to decreased immune function and reproductive issues
• C. It has no real impact on productivity
• D. It generally improves growth rates

Answer: (B)

Stress can significantly impact animal health and productivity, primarily leading to decreased immune function and reproductive issues. When animals experience stress, their bodies release stress hormones like cortisol, which can suppress the immune system. This suppression makes animals more susceptible to diseases and infections, ultimately affecting their overall health. Furthermore, stress can interfere with reproductive performance by disrupting normal hormonal balances required for reproduction. Animals under stress may experience irregular estrous cycles, low fertility rates, and difficulties during pregnancy, all of which negatively affect their capacity to produce offspring. In contrast, the other options suggest enhancements or neutrality in the effects of stress. For instance, stress does not enhance immune function; rather, it compromises it, and it certainly does not improve growth rates or have no impact on productivity. Understanding how stress affects these areas is crucial for managing animal health and ensuring optimal productivity in livestock.
