The duties of a livestock agent focus on buying and selling farm animals on behalf of their clients. As a livestock agent, you generally advise farmers about which livestock to purchase based on their needs and current market conditions. You act as a go-between for the buyer and seller, and you can find animals that meet the specifications of a dairy farm operation or meat processing plant. Your duties and responsibilities sometimes include arranging an auction for a client or a group of farmers in a specific area. While some agents specialize in a specific type of livestock, it largely depends on the type of industry in your area.
