Problems solved by technology

[0003] Fishmeal is the main protein raw material in aquafeeds. With the shortage of resources and rising prices, the cost of farming will increase. Finding new alternative resources is an inevitable development trend. Nutritional factors damage the intestinal epithelial cells of animals to a certain extent, damage the intestines and liver, cause intestinal inflammation, and then affect the growth and health of animals

Embodiment 1

[0019] Select 30g of rice field eel grouping, design 4 treatment groups (the addition ratio of above-mentioned black soldier fly larva powder is 0, 5.26%, 10.52% and 15.78% respectively, mark as fish meal control group, insect powder group 1 (black water in table 1 horsefly larva powder 2.5%), insect powder group 2 (5% of black soldier fly larva powder in Table 1) and insect powder group 3 (7.5% of black soldier fly larva powder in table 1), each group of feed is equal to nitrogen and other energy ), each treatment group set up 3 parallel, a total of 12 net cages, the size of the net cage is 1.5m×2.0m×1.0m, each net cage put 100 eels, and feed them at 2-3% of body weight every day feed, once a day. The specific formula is shown in Table 1 (the preparation method is to mix the ingredients according to their content evenly). The rice field eel was cultured in the Datang cage for 56 days, and 2 rice field eels were randomly selected in each cage to take the back muscle for textur...

Embodiment 3

[0026] Select the yellow catfish with an average weight of 25.16g and divide it into two treatment groups (control group and insect powder group, the addition of black soldier fly larvae powder in the insect powder group is 2.6% and 5.2% respectively), and the feed composition is shown in Table 3 (the preparation method is to mix each component according to its content and get final product). Each group has 3 repetitions, and each repetition has 40 fishes. A period of 56 days of culture experiments is carried out in the net cage. After weighing, 2 fishes are randomly selected in each tank. The back muscle of catfish was used for texture determination, and the results are shown in Table 4. The results found that compared with the control group, the insect powder group could improve the hardness, adhesiveness, chewiness, cohesion and recovery of the yellow catfish muscle, significantly improve the adhesion and improve the meat quality.

Embodiment 4

[0033] The perch with an average weight of 111.06g was selected and divided into two treatment groups (control group and insect powder group, the content of black soldier fly larvae powder added to the insect powder group was 16.09%). The feed composition was shown in Table 5, and each group had 3 repetitions , each replicated 30 fish, and carried out a 56-day breeding test in a net cage. After weighing, 2 perch were randomly selected from each tank to take the back muscle for texture determination. The results are shown in Table 6. It was found that compared with the control group, the insect powder group could improve the hardness, adhesiveness, adhesiveness, chewiness and cohesion of the perch muscle, thereby improving the meat quality.

Abstract

The invention discloses an application of black soldier fly larvae to a feed for improving meat quality of aquatic products. Black soldier fly larva powder is added to a feed for aquatic products, andthe black soldier fly larva powder is rich in various nutrient components and functional components, so that the intestine environment of the aquatic animals can be improved, the absorption of the nutrient components in the feed by the aquatic animals can be strengthened, meat quality texture indexes of the muscle elasticity, the adhesiveness, the chewiness, the hardness, the adhesiveness, the cohesion, the recoverability and the like, of the aquatic animals of finless eels, pelteobagrus fulvidraco, japanese sea perches and the like are notably improved, and the application has favorable application prospect and market value.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture feed, and in particular relates to the application of black soldier fly larva powder in the preparation of feed for improving the meat quality of aquatic products. Background technique: [0002] my country is the world's largest aquaculture country, accounting for about 70% of the world's total aquaculture. In 2016, the output of aquatic products in my country reached 69 million tons, the export exceeded US$20 billion, the total output of aquaculture reached 50 million tons, and the output of aquatic feed was nearly 17 million tons, becoming the global leader in aquatic feed production. At present, the development of aquaculture in my country relies more and more on the scientific and technological progress of nutrition and feed. According to the "National Agricultural Modernization Plan (2016-2020)", the expected output of national aquaculture aquatic products will reach 52.4 million tons i...
