Problems solved by technology

Fishmeal is widely used in aquatic feed due to its high protein content, rich in amino acids, vitamins and other nutrients; but since the early 1990s, due to overfishing, the production of Peruvian fishmeal has gradually declined, resulting in a decrease in imports; on the other hand, Since 2012, the production of fishmeal in my country has also continued to decrease; in the case of shortage of imports and insufficient domestic production capacity, it is of great significance to find a protein source with high feed utilization rate and abundant sources to replace fishmeal

Embodiment Construction

[0013] Experimental materials and methods

[0014] Fishmeal was purchased from Tianjin Chenhui Co., Ltd. Hemoglobin powder was purchased from Jianrun Biotechnology Co., Ltd. Corn gluten powder was purchased from Xiangxiang Animal Industry Co., Ltd. The large daphnia powder was purchased from a farmer in Baodi, Tianjin, and the fish used in the experiment were purchased from Tianjin Lanke Aquaculture Co., Ltd. The feed raw materials are all crushed and passed through a 60-mesh sieve. Embodiments Y1-Y6 weighed each raw material according to the formula in Table 1 and mixed them thoroughly, made pellet feed with a particle size of 2mm with a granulator, matured in an oven at 90°C for 40min, air-dried in a cool place, grouped and sealed in sealed bags and Store in a -20°C freezer for later use. .

Abstract

The present invention discloses a compound feed used for improving immunity of pelteobagrus fulvidraco and reducing NO2- in water body and an application thereof. The compound feed is characterized byconsisting of fish meal, soybean meal, flour, blood globulin powder, corn protein powder, expanded soybeans, bran, monocalcium phosphate, peanut meal, soybean oil, carboxymethyl cellulose, zeolite powder, a premix and daphnia magna powder. The fish meal, daphnia magna powder and soybean meal account for 45%-55% of the total mass of the compound feed, a mass ratio of the fish meal to soybean mealis (1.4-1.6):1, and a mass ratio of the fish meal to the daphnia magna powder is 0.15-2.4.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and further relates to an immune regulation technology for fish and a culture water regulation technology, in particular to a compound feed for improving the immunity of yellow catfish and its application. Background technique [0002] Pelteobagrus fulvidraco belongs to the order Silurformes (Silurformes), the family Bagride (Bagride), and the genus Pelteobagrus (Pelteobagrus). Water systems, especially streams, lakes and ponds in the middle and lower reaches of the Yangtze River. Yellow catfish is favored by consumers and producers because of its tender meat, high meat yield, short breeding cycle, good benefits, and small size, which is convenient for family consumption. It is an excellent species for export and foreign exchange. The research on catfish is getting more and more in-depth. Fishmeal is widely used in aquatic feed due to its high protein content, rich in amino acids, vitamins ...
