Horses typically have higher ----- values than other species.

• A. AST
• B. ALP
• C. ALT
• D. GGT

Answer: (A)

The main idea is that enzyme levels vary between species, and some are naturally higher in certain animals due to physiology. In horses, AST (aspartate aminotransferase) tends to run higher in the blood than in many other species because AST is present in large amounts in skeletal muscle as well as the liver. Horses have a lot of muscle mass, and routine muscular activity can release AST into circulation, so baseline values for this enzyme are higher than in other species. ALT is more liver-specific and often remains lower in horses unless there’s liver damage. ALP can be elevated in young, growing horses due to bone growth, but that isn’t a general baseline tendency across all ages. GGT elevations are typically more related to biliary issues and can vary with age and other factors, not a general baseline higher value in horses. Thus, AST stands out as the enzyme that typically has higher values in horses compared with other species.
