preparation example Construction

[0051] A method for preparing extruded feed that helps to improve raw fish meat quality and flavor, wherein the refined fish oil is a liquid raw material, and the rest of the raw materials are solid, and it is characterized in that it includes the following steps:

[0052] Step 1, raw fish special vitamin premix, raw fish minerals and other functional premixes, and flavor-improving Chinese herbal medicine preparation mixture are prepared as required;

[0053] Step 2, according to the requirements of formula design, transfer the weight of the above-mentioned different solid raw materials into the batching bin, and take each raw material by mass ratio;

[0054] Step 3, after mixing all the solid raw materials evenly, after passing through the ultrafine pulverizer, the mixture can pass through a 200-320 μm sieve;

[0055] Step 4, the raw material obtained in step 3 is subjected to high temperature and high pressure extrusion, puffing and granulation through an extruder;

Embodiment 1

[0065] Among the extruded feeds that help improve the quality and flavor of raw fish, in air-dried terms: 28.7 parts of Peruvian super fish meal, 7 parts of chicken bone meal, 10 parts of soybean meal, 6 parts of pork powder, 5 parts of spray-dried blood globulin powder, 3 parts of squid offal powder, 4 parts of soy sauce residue, 6 parts of soybean protein concentrate, 19 parts of high-gluten flour, 3.3 parts of refined fish oil, 2 parts of raw fish vitamin premix, 4 parts of raw fish mineral and other functional premix, 2 parts of flavor-improving Chinese herbal preparation mixture.

[0066] After the above raw materials are pulverized, they are mixed according to the above ratio, and after ultrafine pulverization, they are extruded and granulated by an extruder under high temperature and high pressure. The crude protein content of the compound feed in this embodiment is 48.6%, and the crude fat content is 6.8%.

Embodiment 2

[0083] The puffed feed of the present invention, which helps to improve the meat quality and flavor of raw fish, was tested in large ponds in farms. The results showed that Mr. Liang, Sanjiao Town, Zhongshan City, used two ponds for testing. The control group was fed extruded feed that could improve the meat quality and flavor of raw fish, and the control group was fed ordinary raw fish extruded feed.

[0084] The water surface of the farm in the test group was 5.7 mu, and 47,000 fish were released, with an average of 39 fish per catty, and 2,679 bags of materials were used. From June 3, 2018 to December 11, 2018, the breeding cycle was 191 days, and the cumulative weight gain was 102,197.2 Jin commercial fish, the feed coefficient is 1.04, the breeding process is smooth, and there is almost no loss.

[0085] The water surface of the breeding farm in the control group was 3.5 mu, and there were 30,000 raw fish in Dingtang, with an average of 39 per catty, and 1,469 bags of mat...

Abstract

The invention relates to puffed feed beneficial to improvement of flesh quality and flavor of snakeheads and a preparation method of the puffed feed. The puffed feed comprises, by weight, 25-30 partsof Peru super fish meal, 5-10 parts of chicken bone meal, 8-15 parts of soybean meal, 5-10 parts of pork powder, 2-7 parts of spray-dried animal blood cells, 2-5 parts of squid visceral powder, 3-5 parts of soy sauce residues, 5-10 parts of soy protein concentrates, 15-25 parts of high-gluten flour, 3-5 parts of refined fish oil, 2 parts of snakehead vitamin premix, 4 parts of snakehead minerals and other functional premix, and 2 parts of flavor-improved traditional Chinese herbal preparation mixtures. Compared with conventional common snakehead materials, the puffed feed has the advantages that the flesh quality of culture species is improved, the differentiation of snakehead aquatic products is promoted, the added value of products and fishermen's income are increased, and the puffed feed is beneficial to the sound development of the snakehead farming industry.

Description

technical field [0001] The invention relates to an extruded feed for raw fish, in particular to an extruded feed for improving the meat quality and flavor of raw fish and a preparation method thereof. Background technique [0002] Hybrid raw fish (collectively referred to as "raw fish" in the text) is a common name for hybrid snakeheads. It is the hybrid offspring of black snakeheads and spotted snakeheads. It has been cultured in my country for more than ten years and is an important cultured species in South China. Raw fish is large and grows fast, and it is a rare economic fish with high economic value. [0003] Raw fish has no intermuscular spines, and the meat yield is about 4% higher than that of tilapia and channel catfish. It is especially suitable for processing into high-quality frozen meat slices for sale. [0004] Raw fish grows fast and the breeding cycle is short. Under the existing conditions of artificial breeding, it can be raised in the same year, and can...
