Embodiment 1

[0031] In a freshwater fish breeding base, 90 days after the fish fry were put in, they started feeding selenium-enriched eel feed. The fish feed consists of the following:

[0032] (1) Select the above-mentioned selenium-enriched grain powder, imported fish meal, chicken meal, cuttlefish viscera powder, rapeseed meal, and soybean meal that have been cleaned and iron-removed, respectively crushed and passed through a sieve with a diameter of 2 mm, and subjected to ultrafine crushing treatment (The particle size is guaranteed to pass through a 100-mesh sieve);

[0033] (2) Take 8 parts of the crushed selenium-enriched grain powder, 25 parts of imported fish meal, 16 parts of chicken meal, 2 parts of cuttlefish viscera powder, 12 parts of rapeseed meal, and 11 parts of 57% soybean meal;

[0034] (3) Take 3 parts of the above-mentioned molasses yeast, 5 parts of full-fat soybean powder, 3 parts of soybean lecithin, 0.3 parts of multidimensional compound, 0.7 part of compound min...

Embodiment 2

[0042] Composition of raw materials and processing methods are the same as in Example 1, and the weight ratio of each component is: 10 parts of selenium-enriched grain powder, 24 parts of imported fish meal, 17 parts of chicken meal, 2 parts of squid offal powder, 9 parts of rapeseed meal, 57% soybean meal 9 parts, 3 parts of molasses yeast, 4 parts of full-fat soybean powder, 3 parts of soybean lecithin, 0.3 parts of multidimensional compound, 0.7 part of compound mineral salt, 3 parts of calcium dihydrogen phosphate, 0.6 part of choline chloride, 1.4 parts of allicin , 2 parts of refined fish oil, the feed preparation method is the same as in Example 1, and the selenium content in the feed is 560 μg / kg.

[0043] Feed the feed of the present invention and common feed to the fish market, sample detection of meat selenium content, organic selenium ratio and plasma superoxide dismutase activity in the fish body, malondialdehyde content, other indicators of statistics are as shown...

Embodiment 3

[0048] Composition of raw materials and processing methods are the same as in Example 1, and the weight ratio of each component is: 12 parts of selenium-enriched grain powder, 23 parts of imported fish meal, 15 parts of chicken meal, 2 parts of squid offal powder, 8 parts of rapeseed meal, 57% soybean meal 8 parts, 3 parts of molasses yeast, 4 parts of full-fat soybean powder, 3 parts of soybean lecithin, 0.3 parts of multidimensional compound, 0.7 part of compound mineral salt, 3 parts of calcium dihydrogen phosphate, 0.6 part of choline chloride, 1.4 parts of allicin , 2 parts of refined fish oil, the feed preparation method is the same as in Example 1, and the selenium content in the feed is 610 μg / kg.

[0049] Feed the feed of the present invention and common feed to the fish market, sampling and detection of meat selenium content, organic selenium ratio and plasma superoxide dismutase activity in the fish, malondialdehyde content, other indicators of statistics are as show...

Abstract

The invention discloses selenium-rich feed for improving immunity of rice field eel and a preparation method thereof. The selenium-rich feed is prepared by mixing selenium-rich grain meal, imported fish meal, chicken meal, molasses yeast, squid organ meal, rapeseed meal, soybean meal, refined fish oil, whole-milk soybean meal, soybean lecithin, vitamin complex, composite mineral salt, monocalcium phosphate, choline chloride and allicin. The invention solves the problems that the rice field eel artificially cultured by the existing feed has low immunity and is susceptible, the sick rice field eel is hard to cure with common medicines and the rice field eel is relatively sensitive to common medicines. The selenium-rich feed disclosed by the invention does not obviously influence the productivity of rice field eel, and can obviously improve the activity of plasma superoxide dismutase of the rice field eel (P<0.05), remarkably reduce the content of malonaldehyde in the plasma (P<0.05), improve the immunity of the rice field eel and avoid infection.

Description

technical field [0001] The invention relates to a selenium-enriched feed for improving eel immunity and a preparation method thereof. Background technique [0002] Selenium is an essential trace element in animals. It has strong antioxidant properties and is an important part of the antioxidant enzyme glutathione peroxidase (GSH-PX) in the body. It can improve the body's immunity and Disease resistance, antagonizes heavy metals in the body. [0003] As a traditional delicacy suitable for all ages, rice field eel has a long fishing, breeding and eating habit in our country. In recent years, there have been various problems in rice field eel breeding, and now there is an urgent need for a high-quality feed that can improve the immunity and disease resistance of rice field eels, so as to improve the success rate of rice field eel farming. The trace element selenium, as an essential trace element in animals, can effectively improve immunity, so the development of a selenium-en...
