Which of the following describes grazing multiple species together to share parasites?

• A. Pasture rotation
• B. Mixed grazing
• C. Mixed/Alternate grazing
• D. Copper oxide wire particles

Answer: (C)

The idea being tested is mixed-species grazing, sometimes called mixed or alternating grazing. This approach uses more than one livestock species on the same pasture to disrupt parasite transmission. Many gastrointestinal parasites are more adapted to one host, so when multiple species share the same pasture, the parasite pressure is spread across different hosts and is less intense for any single species. The result is a dilution of infection risk and a reduction in parasite load without relying solely on chemical dewormers.

Pasture rotation, by contrast, involves moving animals between paddocks but typically within the same species and isn’t about sharing parasites across species. Copper oxide wire particles are a deworming aid, not a grazing management method.
