随着我国市场经济的发展 ,养殖业的经济效益已经随市场供求关系而发生了明显的变化。畜产品必须以流通为前提 ,只有存在消费市场 ,养殖业才可持续发展。我国南方的养鸭业也是如此。鸭子养殖生产的增长速度已经超过了居民收入的增长速度 ,走上了一条自主经营、自负盈亏的道路。 With the development of market economy in our country, the economic benefits of aquaculture have undergone obvious changes with the supply and demand of the market. Livestock products must be based on the principle of circulation. Only when there is a consumer market can the livestock industry be sustainable. Duck farming in southern China is also true. Duck farming production growth rate has exceeded the rate of increase in resident income, embarked on a self-employed, self-financing road.
