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.

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 yellow catfish.
[0047] Set up the experiment, each group includes 50 adult pelagic pelagic fish with the same weight, body length, and health. The control group is the existing adult pelican fish compound feed. The experimental group is the extruded compound feed of this embodiment. 3 parallel, the experimental period is 3 months; by comparison, the feed conversion efficiency of yellow catfish fed with the extruded compound feed of this example is 27.3% higher than that of the control group, the incidence rate is 64% lower than that of the control group, and the average weight gain rate is increased 21.2%.
[0048] It can be seen that, compared with other compound feeds at adult stage of Pelteobagrus fulvidraco, the extruded compound feed of Pelteobagrus fulvidraco provided by the present invention has low cost, good attractivity, fast growth, less morbidity, normal body color and meat quality. And the flavor is close to the effect of natural wild yellow catfish, and the economic benefits are good.

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 yuan/ton. The extruded compound feed has good attractivity, and the body color of yellow catfish is close to the effect of natural wild yellow catfish.
[0054] Set up the experiment, each group includes 50 pelagic pelargonillas with the same weight, length, and health. The control group is the existing pelagic pellet stage compound feed. The experimental group is the extruded compound feed of this embodiment. Each group is set 3 parallels, the experimental period is 3 months; by comparison, the average weight gain rate of yellow catfish fed with the extruded compound feed of this embodiment is increased by 26.8%, the feed coefficient is reduced by 36.1%, and the incidence rate is reduced by 63%.
[0055] It can be seen that the extruded compound feed for yellow catfish provided by the present invention has better attractivity, high weight gain, low feed coefficient, and high survival rate compared with other mixed feeds for juvenile yellow catfish. The color is the effect of natural wild body color.

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.
