Alternatives to Antibiotic Use for Growth Promotion in Animal Husbandry
註釋Since the 1940s, the use of antibiotics in food animals has become widespread for disease prevention and treatment, feed efficiency and growth promotion. Intense debate and research continue in an attempt to define the contribution of agricultural antibiotics to antibiotic resistance in bacteria that cause human illness. The European Union in general and several individual countries prohibit the use of certain antimicrobial drugs in animal feeds for growth promotion. These concerns lead to a reduced probability of new human antibiotics being approved for use in animal feed, pressure to revoke certain current human antibiotics approved for animal feed, higher costs to produce animals for human food, and opportunities to develop new products for increasing feed efficiencies and growth promotion in food animals.
