Which environmental management practice supports prevention of external parasites?

• A. Ensure proper drainage in the area
• B. Increase water usage without limits
• C. Overstock pens with animals
• D. Remove manure management practices

Answer: (A)

Preventing external parasites is largely about removing their favorable living conditions, especially moisture and waste buildup. When the area has proper drainage, water and mud don’t accumulate, so bedding dries faster and parasites that thrive in damp, dirty environments—like certain flies and mites—have fewer habitats. A dry, well-ventilated, clean area also reduces moisture-loving pests and makes it harder for parasites to survive on animals and in housing corners. In contrast, increasing water usage, overcrowding, or eliminating manure management would create more damp, crowded, and dirty conditions that parasites exploit. So ensuring proper drainage directly lowers the environmental factors that support external parasites, making it the best choice.
