Which animals are observed in motion from both sides during ante-mortem inspection?

• A. Pigs only
• B. Cattle and animals other than swine and lambs
• C. Sheep and goats
• D. Birds and poultry

Answer: (B)

The maneuver being tested is how ante-mortem inspection uses movement to evaluate health. Observing animals in motion from both sides lets the inspector detect signs that aren’t as clear from a single vantage—things like unilateral lameness, asymmetry, or other gait abnormalities that point to illness or injury. This dual-side observation is specified for cattle and other animals that are not swine or lambs, because their size, gait, and conformation make lateral viewing particularly informative for picking up subtle problems.

Birds and poultry follow a different inspection approach suited to their anatomy, so they aren’t assessed in this same dual-side motion way. Pigs and lambs have distinct protocols as well, which is why the general rule isn’t applied to them.
