Which of the following is NOT an ionophore used in livestock?

Explanation:
Ionophores are a class of feed additives that act as ion carriers, shuttling ions across microbial cell membranes to disrupt ion balance and inhibit certain microbes. In livestock, they’re used to improve feed efficiency and to help control coccidiosis in poultry. Examples include Monensin, Lasalocid, and Narasin, which are all polyether ionophores used for these purposes. Rifampin, on the other hand, is a rifamycin antibiotic that inhibits bacterial RNA synthesis; it does not function as an ionophore and is not used as a feed additive in livestock. That’s why Rifampin is not an ionophore used in livestock.
