What may be a consequence of introducing carriers of disease into the cattle herd?

1. Increased growth rate

2. Spread of disease

3. Enhanced immune response

4. No significant changes

The correct answer is: Spread of disease

Introducing carriers of disease into the cattle herd leads to the spread of disease primarily because these carriers can transmit pathogens to healthy animals. This can disrupt herd health, increase veterinary costs, and reduce overall productivity by causing illness and lowering the quality of livestock. The presence of disease carriers can result in widespread infection, making it essential for herdsmen to implement biosecurity measures to manage and mitigate such risks. Consequently, maintaining a healthy herd is crucial for the sustainability and profitability of cattle operations.
