Poultry Judging Practice Test

Question: 1 / 515

Which of the following is NOT a disease vector that can introduce infection agents into a flock?

People

Infected eggs

Rodents

Vaccine

A vaccine is designed to stimulate the immune system and protect birds against specific infectious diseases. It contains weakened or inactivated forms of pathogens or their components, which help the poultry develop immunity rather than act as a vector for disease. Vaccines are an essential part of disease prevention in poultry flocks and are not a means of introducing infectious agents. In contrast, people, infected eggs, and rodents can carry and spread pathogens that may cause disease in a flock. These can transfer infectious agents through direct contact or contamination, making them valid vectors for introducing infections. Understanding the role of vaccines in disease management helps emphasize their importance in maintaining flock health and biosecurity.
