Do grass-fed cows get antibiotics?

Is monensin an antibiotic?
Monensin was the first ionophoric antibiotic approved for use by the Food and Drug Administration (FDA) in the USA. Monensin A is an antibiotic which is used as coccidiostat and growth promoting agent in veterinary practice.
What are some alternatives to treating livestock with antibiotics?
Vaccines are among the most promising and widely used of these alternatives, but pre- and probiotics and other innovative products are also in use or currently being investigated. Many of these have been shown to simultaneously prevent infection and improve animal performance, such as growth rates or egg production.
Does grass fed mean no antibiotics?
Keep in mind: The USDA’s grass-fed label refers strictly to the animal’s diet and has nothing to do with whether it did or did not receive hormones or antibiotics.
Are grass fed cows treated better?
Grass-fed beef production is clearly more humane than CAFO production, especially because the animals are not confined in a feedlot. Cattle are ruminants; confinement in a crowded dirt plot with hundreds or thousands of other animals stifles their natural behaviors.

What is monensin made of?
Monensin A, (Scheme 1) also called monensic acid, MONA, or MonH, occurs as a monohydrate with a water molecule complexed inside. The molecule of this ionophore contains six oxygen atoms, five of which may participate in the complexation of cations.

They are growth promotants, but the advantages to animal health are often overlooked. They prevent bloat and acidosis.
What is medicated feed used for in cattle?
