Which of the following is listed as a trend in animal agriculture?

• A. Increased bio-security
• B. Reduced emphasis on waste management
• C. Decreased demand for hormone-free products
• D. Isolating farms to prevent interactions

Answer: (A)

In animal agriculture, a major trend is strengthening disease prevention across operations. Producers are investing in higher bio-security to reduce the chance of diseases entering or spreading on farms. This means stricter controls at entry points, thorough sanitation and disinfection, quarantine for new stock, protective clothing and gear, wildlife and pest management, safe handling of feed and water, and ongoing disease monitoring. All of these steps reflect a growing emphasis on keeping animals healthy and preventing outbreaks, which protects productivity and meets regulatory and market expectations.

The option that fits this trend is increasing bio-security, because it captures the industry-wide move toward tighter disease prevention. The other ideas don’t align with current directions: waste management is actually becoming more, not less, prioritized due to environmental and regulatory pressures; consumer demand for hormone-free products is generally increasing, not decreasing; and isolating farms is a tactic that can be part of bio-security, but the broader, more accurate trend is the overall rise in bio-security measures across the sector.
