General principles of duck feed preparation

1. To make full use of local feed resources, we should not only consider the nutritional value, but also pay attention to the low price in order to reduce the cost.

2. The matching diet should be close to the feeding standard, so as not to cause lack of nutrition or excessive nutrition, resulting in some nutritional deficiencies or economic losses.

3. Pay attention to the quality and palatability of the diet, and avoid preparing the diet with mildew or raw materials containing harmful substances. The amount of feed should not be too much each time, and it is appropriate to finish it within 7-10 days to keep the feed fresh.

4. All kinds of feed must be fully mixed, especially various additives such as vitamins, trace elements and drugs, and pay more attention to mixing well, otherwise it will cause adverse consequences.

5. The diet should be relatively stable, and when it must be changed, it is best to have a transitional period of one week. It should be paid more attention especially during the peak period of egg production.

6. The content of crude fiber in the diet should not be too high, generally no more than 5%, preferably about 3%.

7. there should be as many kinds of feed as possible in order to complement each other in nutrition and learn from each other. Zeng Qingjun
