Description

Technical Field

[0001] The invention relates to the technical field of marine aquatic feed, and in particular to a marine aquatic feed and application thereof. Background Art

[0002] As an important part of the development of marine economy, aquaculture industry occupies an important position in the whole marine strategic development system. The development of safe, efficient and environmentally friendly marine aquaculture industry is of great significance to alleviating the problems of national energy security, food security and water resources security. In recent years, the output of marine aquaculture in the world has increased year by year, and the rapid development of aquaculture industry has become increasingly dependent on the scientific and technological progress of nutritional feed. As a major aquatic country in the world, my country's contribution rate of aquatic animal nutrition research and feed development and application in aquaculture industry is about 40%, and feed cost accounts for 60%-70% of aquaculture cost. The development of aquaculture industry has an urgent need for feed technology research.

[0003] Atlantic salmon is a cold-water migratory fish of the family Salmonidae in the order Salmoniformes. This fish was first named "Salmo salar" by Swedish naturalist Linnaeus in 1758, where "salar" comes from the Latin "salio", which means "jump". Because its English name Salmon is pronounced similarly to "Salmon", Atlantic salmon is often called "Salmon" in China. Atlantic salmon has a spindle-shaped body, a silver-blue back, and black spots above the lateral line. From the sides of the abdomen to the abdomen, the color gradually changes from silver to white. In addition, the meat of Atlantic salmon is a unique orange-red.

[0004] Freshwater aquaculture is currently developing rapidly. It has been found that the survival rate of Atlantic salmon raised in freshwater is low, and its meat is lighter in color and of poorer quality. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a marine aquatic feed and application. The feed of the present invention can be used to raise Atlantic salmon in fresh water, which not only improves the survival rate of Atlantic salmon, but also improves the quality of Atlantic salmon.

[0009] Furthermore, the components of the red palm oil include vitamin E, β-carotene, saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids, and the content of α-linolenic acid in the polyunsaturated fatty acids is 0.

[0010] Furthermore, the content of vitamin E is 1500ppm.

[0011] Furthermore, the content of β-carotene is 2500 ppm.

[0012] Furthermore, the content of the saturated fatty acid is 40wt%.

[0024] The embodiments of the present invention have the following technical effects: 1. First, in freshwater aquaculture, the feed of the present invention is added with Schizochytrium powder containing a large amount of DHA (docosahexaenoic acid), and the Schizochytrium powder of the present invention can significantly improve the survival rate of Atlantic salmon; secondly, the feed of the present invention also contains red palm oil, which contains 1500ppm of vitamin E and 2500ppm of β-carotene, which can not only work together with the Schizochytrium powder to improve the survival rate of Atlantic salmon, but also improve the color quality of Atlantic salmon; finally, the other ingredients in the feed of the present invention are used to meet other needs for the growth of Atlantic salmon.

[0025] 2. In the present invention, the red palm oil in the prior art contains α-linolenic acid, which easily causes oxidation of oils and fats, and a large amount of vitamin E and β-carotene will further promote the oxidation of red palm oil, thereby affecting the nutritional components and stability of the final feed. For this reason, in the red palm oil obtained by the present invention, while ensuring that it contains a large amount of vitamin E and β-carotene, the α-linolenic acid in the red palm oil is removed, thereby improving the stability of the red palm oil.

[0026] 3. The feed obtained by the present invention is also used for freshwater breeding of golden pomfret and black tiger shrimp. The results show that the feed of the present invention can also improve the survival rate and quality of golden pomfret and black tiger shrimp in the freshwater breeding process.

Feed was regularly fed 2-3 times a day and routine management was performed. The breeding experiment lasted for 30 days, and the survival rate was tested on the 7th, 17th, 23rd and 30th days. Survival rate (%) = 100 × (aquatic product quantity at the end of the experiment / aquatic product quantity at the beginning of the experiment).

[0058] (2) Stability of red palm oil.

[0059] GB 5009.227-2016 "Determination of Peroxide Value in Foods of National Food Safety Standard" was used for testing. Weigh 2g of the prepared sample (accurate to 0.001g), place it in a 250mL iodine volumetric flask, add 30mL of chloroform-glacial acetic acid mixture, and shake gently to completely dissolve the sample. Accurately add 1.00mL of saturated potassium iodide solution, plug the bottle cap tightly, and shake gently for 0.5min, and place it in the dark for 3min. Take it out and add 100mL of water. After shaking well, immediately titrate the precipitated iodine with sodium thiosulfate standard solution (when the estimated peroxide value is 0.15g / 100g or less, use 0.002mol / L standard solution; when the estimated peroxide value is greater than 0.15g / 100g, use 0.01mol / L standard solution). When the titration reaches light yellow, add 1mL of starch indicator, continue titration and shake vigorously until the blue color of the solution disappears as the end point. Perform a blank test at the same time. The volume V0 of 0.01mol / L sodium thiosulfate solution consumed in the blank test shall not exceed 0.1mL. The peroxide value on day 0 was used as the control for each group, which was set as 1.0. The peroxide value was measured on days 7 and 14. The relative peroxide value = (peroxide value after the experiment) / (peroxide value at the beginning of the experiment).

[0060] Results and Analysis: Table 1 Survival rate of Atlantic salmon

[0061] Table 2 Survival rate of golden pomfret

[0062] Table 3 Survival rate of black tiger shrimp

[0063] In freshwater aquaculture, the Schizochytrium powder and red palm oil in the feed of the present invention play a significant role in the feed, and improve the survival rate of Atlantic salmon, golden pomfret and black tiger shrimp, as verified by the comparison of Example 1 and Comparative Examples 1 to Comparative Examples 3 in Tables 1 to 3. It can be seen that the present invention significantly improves the survival rate of marine organisms due to the large amount of DHA in the Schizochytrium powder and 1500ppm of vitamin E in the red palm oil, and 2500ppm of β-carotene can also improve the color quality of Atlantic salmon.

[0064] In the present invention, the stability of the red palm oil of the present invention was also tested. The red palm oil of the present invention was used as a control group, and then compared with α-linolenic acid added with 1% of red palm oil and α-linolenic acid added with 2% of red palm oil. The results are as follows: Figure 1As shown. It can be found that the red palm oil of the present invention has good stability, while the stability of the red palm oil with α-linolenic acid added decreases with the increase of the amount of α-linolenic acid added. It can be seen that in the red palm oil of the present invention, when α-linolenic acid is added, the stability of the red palm oil will be significantly reduced due to the large amount of vitamin E and β-carotene in the ingredients. Therefore, the red palm oil in the present invention does not contain α-linolenic acid, thereby ensuring the effect of red palm oil and improving its stability, which is beneficial to the stability of the final feed.
