Embodiment 1

[0043]

[0044] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The procedure shown prepares extruded compound feed.

[0045] The extruded compound feed prepared in this embodiment has a crude protein content ≥ 38%, and is suitable for feeding yellow catfish (≥ 20 g) in the fish breeding stage.

[0046] Compound feed with the existing yellow catfish adult fish stage (30% of steamed fish meal, 33% of peeled soybean meal, 4% of corn gluten meal, 6% of puffed corn, 20% of flour, 3% of soybean oil, 1% of calcium dihydrogen phosphate, ore Substance 1%, betaine 0.5%, choline chloride 0.5%, salt 0.5%, marigold plant extract 0.3%, fish multidimensional 0.2%) compared, the cost of the expanded compound feed prepared by the present embodiment is reduced by 1700 yuan / ton, and good food attractant, the body color of yellow catfish is normal, and the meat quality and flavor of the product are close to the effect of natural wild yellow cat...

Embodiment 2

[0050]

[0051] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The procedure shown prepares extruded compound feed.

[0052] The extruded compound feed prepared in this example has a crude protein content ≥ 45%, and is suitable for feeding yellow catfish (≤ 20 g) in the juvenile fish breeding stage. Since the demand for animal protein in juvenile fish is higher than that of adult fish, the proportion of fish steak powder should be appropriately increased in the formula.

[0053] Compound feed with the existing yellow catfish juvenile stage (35% steam fish meal, 28% peeled soybean meal, 11% corn gluten meal, 18% flour, 4% soybean oil, 1% calcium dihydrogen phosphate, 1.5% minerals, sugar beet Alkali 0.4%, choline chloride 0.4%, salt 0.2%, marigold plant extract 0.2%, fish multidimensional 0.3%) compared, the cost of the expanded compound feed prepared in the present embodiment reduces 1620 yuan / ton, and the prepared The puffed...

Embodiment 3

[0057]

[0058] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The procedure shown prepares extruded compound feed.

[0059] The extruded compound feed prepared in this example is suitable for feeding yellow catfish whose body color has been "whitened" and "yellowing", which seriously affects the sale of the yellow catfish.

[0060] The puffed catfish extruded compound feed prepared in this example was fed. After feeding for one month, the body color of the tested yellow catfish basically returned to normal, and the meat quality and flavor of commercial fish of the yellow catfish could be obviously improved.

Abstract

The present invention discloses a simulated ecological pelteobagrus flvidraco puffed compound feed. The pelteobagrus flvidraco puffed compound feed is prepared from a powdered feed by mixing, puffingand granulating. The powdered feed consists of the following components in mass percentages: 25%-45% of fish steak powder, 12%-25% of rice bran, 10%-15% of threonine microbial proteins, 15%-20% of flour, 3%-5% of beer yeasts, 1%-3% of calcium dihydrogen phosphate, 1%-2% of minerals, 0.3%-0.8% of betaine, 0.2%-0.5% of choline chloride, 0.3%-0.5% of edible salt, 0.2%-0.5% of curcumin and 0.1%-0.3% of multi-vitamins for fish. Compared with conventional pelteobagrus flvidraco compound feeds, the puffed compound feed has the following advantages: 1, the cost is low; and the fish steak powder is only used to replace fish powder and the feed cost can be reduced by 1,250 yuan to 2,250 yuan / ton; 2, the mortality rate is reduced by 50% or more; and the incidence rate is reduced by 60%-80%; 3, the food intake is increased by 15%-20%; and the feed efficiency is increased by 10% or more; and 4, the body color of the cultured pelteobagrus flvidraco is close to the body color of the wild pelteobagrusflvidraco.

Description

technical field [0001] The invention relates to an aquatic compound feed, in particular to an ecologically imitated puffed catfish puffed compound feed, which belongs to the field of aquatic feed. Background technique [0002] Yellow catfish (Pelteobagrus flvidraco) belongs to the family Siluriformes, Paliidae, and the genus Pelteobagrus. It has nourishing effect and medicinal value. Yellow catfish is widely distributed in waters such as rivers, lakes, reservoirs, ditches, and ponds in my country. It is a bottom-dwelling omnivorous carnivorous freshwater fish with high economic value. In recent years, yellow catfish has been cultured on a large scale in my country's coastal and inland areas. According to the data in the 2017 China Fishery Statistical Yearbook, the annual output of yellow catfish in 2016 was 417,300 tons. Based on the current development situation, the future is estimated In the next few years, the aquaculture area and production of yellow catfish will still...
