4 multiple choice 1 point
which class of livestock is primarily raised for egg production?
broilers
roasters
layers
fryers

Explanation:

First Question (Biosecurity Practice):

• Sharing equipment between farms can spread pathogens, so it's not a preventive practice.
• Allowing visitor access to all areas increases disease entry risk.
• Limiting visitor access reduces exposure, and disinfecting footwear kills pathogens on shoes, preventing disease entry.
• Mixing new animals immediately can introduce diseases from new animals to the existing herd.

• Broilers, roasters, and fryers are types of chickens raised for meat.
• Layers are chickens specifically bred and raised for egg production.

Answer:

C. Limiting visitor access and disinfecting footwear
