Abstract

The invention discloses an aquaculture feed for penaeus chinensis. The aquaculture feed is prepared by main and auxiliary materials. The main materials comprise, by weight, 22-26 parts of fish paste, 23-25 parts of fish meal, 8-12 parts of meat and bone meal, 8-12 parts of blood meal, 10-14 parts of yeast powder, 4-6 parts of sunflower seed cake, 1-3 parts of sugarcane slag powder, 8-12 parts of silkworm chrysalis, 0.8-1.2 parts of fish oil, 6-8 parts of soybean phosphatide, 2-4 parts of cuttlefish paste, 0.2-0.4 part of calcium dihydrogen phosphate, 0.1-0.2 part of green tea powder, and 1-2 parts of black bean powder. The auxiliary materials comprise, by weight, 0.02-0.04 part of insect chitin, 0.01-0.03 part of vitamin premix agent, 0.05-0.07 part of rhizoma polygonati, 0.02-0.04 part of hypericum japonicum, 0.02-0.04 part of medicated leaven, and 0.02-0.04 part of Taibai ginseng. The preparation method comprises the steps of mixing the main materials, granulating, spraying a solution of the auxiliary materials on the particles of the main materials, and drying. Feeding shrimps with the aquaculture feed for penaeus chinensis provided by the invention can promote shrimps to fully absorb nutrition, prevent shrimp diseases, promote shell growth and the shelling of shrimps, improve the yield, and reduce the feed coefficient.

Description

technical field [0001] The invention relates to the field of shrimp and crab feed, in particular to a breeding feed for Chinese prawns. Background technique [0002] With the development of the economy and the progress of the society, people's living standards are getting higher and higher, the diet is becoming more and more scientific, the demand for aquatic products is increasing, and there are more and more aquatic products. Among them, the cultivation of shrimp The amount is increasing, and the demand for feed is also increasing. The shrimp and crab feed sold on the market are not very targeted, and the shrimp is difficult to absorb, and often can only be partially absorbed, resulting in low feed utilization and polluting water sources. , Increase the disease rate of shrimp, reduce the growth rate, and increase the cost of feeding. When the feed of the present invention is fed to shrimps, the nutrients are easily absorbed by the shrimps, and at the same time, it has the...
