Charlie's comment raises a
question--the efficacy of any antibiotic or
pesticide, if applied regularly, tends
to be lost as the pathogen or pest
evolves resistance. Have you seen
any studies that tracked the amount of
benefit to feeding livestock species an
antibiotic over the course of many
years?
Not sure that thought has merit? Livestock of rhis variety is not kept that long. Its moved to market. Or like bees would be succesivegeneratuons. The exceptio. Wouldbe breeding stock. But breedi g stick is generally never put o a high caliber food ? To much weight gain in them is not good so the are kept lean and fed lesser foods unles the show symptoms
