    Use of Antibiotics and Hormones in Animal Feed Antibiotics are chemicals produced by living organisms that are used to kill or inhibit the growth of other infectious micro-organisms. Most antibiotics prevent the growth of microorganisms, which they act on instead of completely killing them.

Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead

The Biosocial Model was developed to encompass the influences and relationships
