Problems solved by technology

In Zhanjiang, Guangdong, the outbreak of trichotillomantis disease in pond carp is mainly around the Qingming Festival, that is, from March to May. In the prior art, prevention is the main method to deal with the problem that pond carp is susceptible to trichotillomania, and the treatment is very difficult. In the past, most of them used More antibiotics are added to the feed, but with the implementation of the ban on antibiotics in the country, it is even more difficult to treat the fish infected with trichomonas
[0004] On the other hand, the natural body color of the local pond carp is bright yellow, but in the actual breeding process, it was found that due to the high density of artificial breeding, there were a lot of dead algae in the breeding water, and the water color was dark green, so the water quality was not good and the fish suffered from disease. The reasons for the poor body color of the pond carp, thus affecting the market demand for the pond carp

Embodiment 1

[0034] A kind of preparation method of the special-purpose feed that significantly reduces pond carp to infect trichotillomantis of the present embodiment is as follows:

[0035] Step a. Weigh 35 parts of soybean meal containing crude fiber, 7 parts of peanut bran, and 8 parts of corn gluten powder in parts by weight, place them in a grinder for primary crushing, and then sieve a sieve with an aperture of 1 mm to obtain primary crushed materials ,spare;

[0036] Step b. Weigh 20 parts of raw fish meal, 4 parts of enzymolyzed chicken blood meal, 8 parts of defatted black soldier fly powder, and 8 parts of wheat flour by weight, put them in a pulverizer, add the primary pulverized materials and mix them, and carry out a secondary ultra-thin Micro-grinding, passing the crushed material through a 80-mesh sieve to obtain a secondary crushed material with a fineness of more than 95%, so as to ensure the uniformity of the feed and help improve the nutrient absorption rate of pond fis...

Embodiment 2

[0044] A kind of preparation method of the special-purpose feed that significantly reduces pond carp to infect trichotillomantis of the present embodiment is as follows:

[0045] Step a. Weigh 22 parts of soybean meal containing crude fiber, 5 parts of peanut bran, and 6 parts of corn gluten powder in parts by weight, place them in a grinder for primary crushing, and then sieve a sieve with an aperture of 1 mm to obtain primary crushed materials ,spare;

[0046] Step b. Weigh 18 parts of raw fish meal, 2 parts of enzymolyzed chicken blood meal, 4 parts of defatted black soldier fly powder, and 10 parts of wheat flour by weight, put them in a pulverizer, add the primary pulverized materials and mix them, and carry out secondary ultra-thinning Micro-grinding, passing the crushed material through a 80-mesh sieve to obtain a secondary crushed material with a fineness of more than 95%, so as to ensure the uniformity of the feed and help improve the nutrient absorption rate of pond ...

Embodiment 3

[0054] A kind of preparation method of the special-purpose feed that significantly reduces pond carp to infect trichotillomantis of the present embodiment is as follows:

[0055] Step a. Weigh 30 parts of soybean meal containing crude fiber, 10 parts of peanut bran, and 5 parts of corn gluten powder in parts by weight, place them in a grinder for primary crushing, and then sieve a sieve with an aperture of 1 mm to obtain primary crushed materials ,spare;

[0056] Step b. Take 8 parts by weight of raw fish meal, 6 parts of enzymatically hydrolyzed chicken blood meal, 7 parts of defatted black soldier fly powder, and 12 parts of wheat flour, put them in a pulverizer, add the primary pulverized materials and mix them, and carry out a secondary supernatant Micro-grinding, passing the crushed material through a 80-mesh sieve to obtain a secondary crushed material with a fineness of more than 95%, so as to ensure the uniformity of the feed and help improve the nutrient absorption ra...

Abstract

The invention relates to the technical field of breeding feeds, and in particular relates to a special feed capable of remarkably reducing trichodina infection of clarias fuscus and a preparation method thereof. The special feed is prepared from the following raw materials in parts by weight: 8 to 20 parts of fish meal, 2 to 6 parts of enzymolysis chicken blood powder, 2 to 8 parts of degreased hermetia illucens powder, 13 to 35 parts of soybean meal, 3 to 12 parts of peanut bran, 3 to 8 parts of corn protein powder, 5 to 15 parts of wheat flour, 2 to 5 parts of fish oil, 2 to 5 parts of soybean oil, 0.1 to 0.4 part of choline chloride, 2 to 4 parts of a premix, 1 to 3 parts of calcium dihydrogen phosphate, 0.1 to 1 part of a yeast culture, 0.2 to 0.8 part of taurine and 0.1 to 0.8 part ofeucalyptus oil. The special feed not only has the advantages of comprehensive nutrition and strong food calling, but also can significantly improve the stress resistance and disease resistance of clarias fuscus, improves the body color of clarias fuscus, and better meets the market requirements.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a special feed for significantly reducing the infection of trichomonas in pond carp fish and a preparation method thereof. Background technique [0002] Pond catfish, scientific name bearded catfish, belongs to tropical and subtropical fish, distributed in various parts of southern my country, especially in Guangdong, Guangxi, Taiwan, Fujian, Yunnan and other places. There are two common species in China: the local catfish (bearded catfish), and the Egyptian pond catfish (leatherbeard catfish, Egyptian bearded catfish). Pond carp likes to flock and is gluttonous. It mainly feeds on animal bait, such as insects, small miscellaneous fish, shrimp, shellfish, etc., and carnivorous fish. Most of its prey objects are small fish, such as table sticks, crucian carp, and chrysalis Tiger fish, wheat ear fish, carp, loach, etc. also eat shrimp and aquatic insects. [0003] Tricho...
