"This has been a really nice winter to feed cattle," said Craig Anderson on a warm February day at his cattle farm near Merrill, Iowa.
Anderson's been raising thousands of cattle a year for about 40 years.
His wife Nancy helps out with the business, too.
Over those years the two of them have seen a lot of changes, but now more new rules could be on the way from the Food and Drug Administration.
"Nobody likes regulations, but the regulations are there for a reason," said Anderson.
Some growers feed their animals the stuff almost all the time, and these new rules hope to stop over use of antibiotics in animal production.
Prohibiting both using antibiotics to make animals grow faster and to help those same animals eat less feed when they're growing.
The new rules are meant to make sure humans don't becoming resistant to the effects of certain antibiotics, from eating animals who've consumed a lot.
But Anderson says the new rules won't affect producers like himself.
He says his cattle only get antibiotics if they're sick, on a case by case basis.
"People that have got children, they can tell when their kid is getting sick and cattle are the same way," said Anderson. "They're standing in the back corner with their head hanging and snot dripping out of their nose and they look like they don't feel good."
And even when those cattle get treated, the treatment only lasts for three to five days at a time.
"That's still going to be okay and we do it under licensed veterinarian supervision," said Anderson.
But it if these rules pass, it could be years before we see how they affect the overall cattle industry.
