Question

g John Smith is a pig farmer. For the past 5 years, Smith has been adding vitamins and low doses of antibiotics to his pig food; he says that these supplements enhance the growth of the pigs. Within the past year, however, several of his pigs died from infections of common bacteria, which failed to respond to large doses of antibiotics. Can you explain the increased rate of mortality due to infection in Smiths pigs

Answer 1

Due to tolerance against antibiotic.

Step-by-step explanation:

The increased rate of mortality occurs in the pigs due to the bacteria which gets tolerance against the antibiotics. The regular use of same antibiotic kills most of the bacteria but in some bacteria mutation occurs that produces tolerance against the antibiotics and there is no effect of antibiotics on then and they are able to cause infection in the organism that leads to death. So the use of same antibiotics is not good for the pigs, the pig farmer should apply different type of antibiotics due to which the bacteria has zero tolerance.
