Ionophores are lipid-soluble compounds that form complexes to transport ions across biological membranes. They play an important role in improving livestock and poultry health and feed efficiency. Ionophores are produced by microorganisms and act by increasing the permeability of cell membranes to specific cations. Common ionophores used in animal feed include monensin, lasalocid, and salinomycin.

2. Ionophores are compounds forming lipid-
soluble complexes that act as vehicles for
transporting ions across biological
membranes .

3. Ionophores play a significant role in
improving the health and feed efficiency
of livestock and poultry production.

4. SUBCLASSES OF IONOPHORES
1- Carboxylic ionophores form zwitterionic
complexes with cations .
2- Promote electrically neutral cation exchange
diffusion.

5. Ionophores antibiotic are compounds
produced by microorganism (mainly
spore-forming) ; they act by specifically
increasing the ion permeability of the cell
membrane.

6. Most ionophores are polyether
antibiotics from Streptomyces species,
with a single carboxylic acid function.

7. Ionophores (polyether antibiotics), such as
(monensin , lasalocid, laidlomycin, salinomycin
and narasin) are antimicrobial compounds that
are commonly fed to ruminant animals to
improve feed efficiency.
