Fengxiang Group has been signing contracts with farmers to ensure the supply of raw materials for broilers. According to the contract, Fengxiang Group provided chicks and feed distribution, and promised to buy all live chickens. At present, the profit margin of broiler feeding is still very large. The feeding cycle of broilers is about 45 days, and the turnover cycle is fast. It can feed about 6 batches a year. The profit of each broiler is around 3-5 yuan. Raising 10000 chickens a year is still very profitable. However, the risk of raising chickens lies in the survival rate of chickens. Without the technology of raising chickens, the survival rate of chickens is low, the number of slaughter is small, and the money earned is small. Especially the prevention and control of chicken plague, the loss caused by this natural disaster is the biggest risk that chickens have to face.
