How to raise fish with duck manure

Prepare fresh duck manure about 100 kg first. Then, the fermented bacteria liquid of Nongshengle manure (1 kg) is diluted with water, and the diluted liquid is evenly mixed with 20 kg of corn flour or wheat bran, mixed until the dry humidity can be spread, directly sprinkled into the prepared fresh duck manure, repeatedly sprinkled with the mixed corn flour, and stirred again until the dry humidity is controlled at 50%. Fermentation lasts for 7- 12 days in winter and 5-7 days in spring and autumn. Fermentation in summer is about 1 to 2 days.

Fermented duck manure looks shiny and gives off a faint smell of wine. Feeding fish to pigs is a good choice!

After feeding the ducks for 4 hours, the duck manure was discharged, and a large amount of undigested feed occupied the crane. Duck manure is rich in high protein, which draws on the experience of duck manure development and utilization in developed countries such as Europe and America. After timely treatment, duck manure was used to feed fish, shrimp, crab, loach, mussel and other aquatic products, which played a good economic value.

Duck manure contains nitrogen 1.64%, phosphorus 1.54% and potassium 0.85%, which is a kind of organic fertilizer with balanced nutrition and high content. It contains 25.5% of various organic substances and can be used as energy raw materials; It contains 7.94% crude protein, including 0. 1 1% methionine, 0.43% lysine and 0. 1% cystine, which can be used as feed.

In China, duck manure has not been processed and utilized in the past, mainly because most ducks in China are still in free-range or semi-free-range state, and it is difficult to collect duck manure. With the gradual development of intensive duck farming enterprises, the intensive treatment of duck manure is particularly important. The processing and utilization of this polluted duck manure not only improves the economic benefits of duck manure, but also is win-win in many aspects such as environmental protection benefits and social benefits.
