There are three major raising contracts in the broiler industry: the market price contract, the guarantee price contract, and an agent contract. Even though those contracts have different regulations and pricing methods, the revenues of growers are still basically determined by the market conditions and individual management conditions. Generally speaking, the market price contract accompanies higher profit with higher risk. The profit and risk in the guarantee price contract are relatively in the median level. There is usually lower profit and risk in the agent contract. Growers could dynamically adjust their contract based on their preference and expected profits. Therefore, the <||>delicate triangle relationship<||> among those contract types could be substantial. Moreover, in the development of contract production, the <||>interactive triangle relationship<||> is hidden among the growers, feedstuff plants, and processing plants.
