← Nature & AnimalsWhich digestive efficiency change occurs in ruminants when antimicrobial exposure decreases microbial diversity?
A)Reduced methane production overall
B)Ammonia toxicity due to protein excess✓
C)More efficient cellulose fermentation
D)Increased volatile fatty acid absorption
💡 Explanation
Antimicrobial exposure lowers competition; proliferation of few species causes inefficient metabolism creating excess ammonia – resulting in toxicity, via microbial imbalance, because less diverse bacteria can't properly regulate protein, therefore it concentrates, rather than completing digestion with other species.
