The use of antibiotics in food animals selects for bacteria resistant to antibiotics used in humans, and these might spread via the food to humans and cause human infection, hence the banning of growth-promoters. The actual danger seems small, and there might be disadvantages to human and to animal health. The low dosages used for growth promotion are an unquantified hazard. Although some antib...

Antibiotics as growth promoters (AGP) in the feed of different animal species have been used for many years to improve feed efficiency and growth. The mechanisms of how antibiotics can promote growth are not well known; nevertheless several studies have focused on interactions between antibiotics and intestinal microflora. However, many scientists have suggested that there may be other modes of...

Background & Aim: Feed additives have been widely used to stimulate appetite, improve growth performance and immune system function in livestock nutrition. For many years antibiotics have been used in livestock production to improve growth performance. Following the ban on the use of antibiotic growth promoters in animal feeds in European Union and increasing demand for organic...

Introduction Following the European ban of antibiotic growth promoters (AGPs) in 2006, the use of organic acids in animal nutrition has gained significant importance in the feed industry. Their positive effects on feed quality and animal performance have been known for decades and, as they increasingly capture the attention of the feed industry, there is a growing need to define the several aci...
