Why should antibiotics be used in agricultural livestock farming?

Practical creation of small series for you to sort out the answer:

The main purpose of using antibiotics in breeding animals is to prevent and control animal bacterial diseases, promote the healthy development of animal husbandry, and ensure the safety of animal products and maintain human health. When the resistance of farmed animals is reduced, disease-causing microorganisms will take the opportunity to cause disease. If not treated in time, the disease can easily spread among farmed animals, seriously affecting animal health, resulting in a decrease in product quality and yield.

Sometimes animal diseases may also infect people, such as streptococcus suis disease, erysipelas, etc. These diseases are called "zoonosis", which is a great threat to the health of both humans and animals. Timely and reasonable use of veterinary antimicrobial drugs can not only protect animal health, but also ensure the quality of animal products, and avoid economic losses. Antimicrobial agents play an important role in the prevention and control of livestock and poultry diseases, which is one of the cornerstones of large-scale and intensive development of livestock and poultry breeding industry in the world today.
