Why are cattle vaccinated and dewormed when they arrive at a feedlot?

When cattle arrive at a feedlot, they are examined, vaccinated, and dewormed as part of standard management practices to ensure animal health and maximize growth efficiency.1

These procedures are essential for several reasons:

• Disease Control: Feedlots house large numbers of animals in confined spaces, creating an environment where pathogens can spread easily. Vaccination helps protect the herd against various infectious diseases, such as bovine respiratory disease, which can cause significant losses.12
• Parasite Management: Deworming is performed using vermifuges to eliminate parasitic worms that can negatively impact an animal's health and ability to gain weight.2
• Optimizing Growth: Because feedlot operations are highly scientific and focused on maximizing weight gain for market, maintaining the health of the cattle is critical. By preventing illness and reducing parasite loads, producers ensure that the animals can efficiently convert their high-energy grain diets into muscle and fat.13

These health interventions are part of a broader, comprehensive management strategy designed to maintain productivity and ensure the uniform quality of the final product.3
