What is the primary purpose of using antibiotics in livestock production?

  1. Improve feed efficiency

  2. Enhance taste of meat

  3. Increase the weight of livestock

  4. Prevent infectious diseases

The correct answer is: Prevent infectious diseases

The primary purpose of using antibiotics in livestock production is to prevent infectious diseases. Livestock are often kept in situations where they may be exposed to various pathogens, especially in intensive farming environments where animals are in close proximity to each other. Administering antibiotics can help control and prevent the outbreak of diseases that could potentially spread through the herd, leading to significant health issues and economic losses for farmers. By using antibiotics in a preventive manner, livestock producers can ensure that animals remain healthy, which in turn helps maintain a stable supply of meat, milk, and other animal products. This practice also contributes to overall animal welfare, as healthy animals are less likely to suffer from disease-related stress and complications. While improving feed efficiency, enhancing the taste of meat, and increasing weight are benefits associated with livestock production practices, they are not the primary reason for antibiotic use. The focus on disease prevention through antibiotic use is crucial for maintaining the health of the livestock and safeguarding public health by minimizing the risk of disease spread from animals to humans.
