AGRC 112 Lecture Notes - Lecture 15: Biome, Ionophore, Antimicrobial Resistance
Document Summary
Sub - therapeutic ionophores to improve ef ciency of rumen fermentation. There are 3 different safety check to make sure there is no antibiotics in milk. Prophylactic / metaphylactic and therapeutic control of respiratory infection. Sub- therapeutic ionophores ( not medically important ) to improve ef ciency of rumen fermentation. 10% use antibiotic growth promotion in grow/ nish. Metaphylactic use to control identi ed enteric/ respiratory infections. They are even vaccinating embryos before they are even hatched. Massive population of bacteria which are not resistant to antibiotics, when you feed it to the animal it kills off the most of the antibiotics but the ones that do not die will recon gure the. The microbes become resistant to the antibiotics and multiply. The antibiotics resistant in one pathogens, the pathogens exchange dna which makes other microbes able to become antibiotics resistant. The microbes develop a metabolic ability to neutralize the antibiotic.
