Example Embodiment

[0042] Example 1,

[0043]

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

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

[0046] Complementary feed with existing yellow catfish at adult stage (steam fish meal 30%, peeled soybean meal 33%, corn gluten meal 4%, expanded corn 6%, flour 20%, soybean oil 3%, calcium dihydrogen phosphate 1%, mineral (1% of substance, 0.5% of betaine, 0.5% of choline chloride, 0.5% of table salt, 0.3% of marigold plant extract, 0.2% of fishery multi-dimensional), the cost of the extruded compound feed prepared in this example is reduced by 1,700 yuan / Ton, and good food attractant, the yellow catfish body color is normal, and the meat quality and flavor of the product are close to the effect of natural wild y...

Example Embodiment

[0049] Example 2,

[0050]

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

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

[0053] Complementary feed with existing yellow catfish juvenile stage (steam fish meal 35%, peeled soybean meal 28%, corn gluten meal 11%, flour 18%, soybean oil 4%, calcium dihydrogen phosphate 1%, mineral 1.5%, sugar beet Compared with alkali 0.4%, choline chloride 0.4%, table salt 0.2%, marigold plant extract 0.2%, fishery multi-dimensional 0.3%), the cost of the extruded compound feed prepared in this example is reduced by 1,620...

Example Embodiment

[0056] Example 3.

[0057]

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

[0059] The extruded compound feed prepared in this embodiment is suitable for feeding the problem of "whitening" and "yellowing" of the body color, which has seriously affected the marketing of yellow catfish.

[0060] Feeding the puffed catfish compound feed prepared in this example, the test pelagic catfish after 1 month of feeding, the body color basically returned to normal, and can significantly improve the meat quality and flavor of the pelagic catfish commercial fish.

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...
