Embodiment 1

[0017] The active ingredient of oyster meat extract is taurine, which can participate in a variety of physiological activities that relieve stress responses, such as relieving cerebral edema caused by glutamine accumulation, reducing the damage caused by inflammatory reactions to the body, regulating calcium homeostasis, Scavenge free radicals, protect tissues from oxidative damage, etc. The fishy smell of oyster meat can also play a good role in attracting food, and cover up the peculiar smell of other traditional Chinese medicine ingredients in the formula to improve palatability; the liver of fish is the main part of stress injury,

[0018] Schisandra can reduce the increase of alanine aminotransferase caused by carbon tetrachloride, thioethanolamine, etc., and the main component γ-Schisandrin has anti-liver damage effect;

[0019] Curcumin in turmeric can effectively inhibit the activity of P450s and glutathione transferase, inhibit the synthesis of collagen and the activi...

Embodiment 2

[0038]Weigh 200 grams of oyster meat extract, 20 grams of toad extract, 50 grams of plantain, 0.15 grams of oleander, 200 grams of schisandra, 200 grams of turmeric, 100 grams of Chuanxiong, 150 grams of angelica, 150 grams of medlar, mix and crush Feed additives were prepared by sieving, with a mesh size of 60, and were added to seawater fish feeds using external spraying technology in an amount of 5%.

[0039] Example 2:

[0040] Weigh 250g of oyster meat extract, 10g of dry toad extract, 20g of plantain, 0.5g of oleander, 100g of schisandra, 100g of turmeric, 500g of chuanxiong, 200g of angelica, 100g of medlar, mix, pulverize and sieve to obtain feed Additive, mesh 60, mixed evenly into seawater fish feed at 8% dosage.

[0041] Comparative experiment 1:

[0042] 200 grams of oyster meat extract, 20 grams of toad extract, 50 grams of plantain, 0.15 grams of oleander, 200 grams of schisandra, 200 grams of turmeric, 100 grams of Chuanxiong, 150 grams of angelica, 150 grams ...

Abstract

The invention discloses a seawater fish feed additive composition and use thereof. The feed additive composition is prepared from the following raw materials in parts by weight: 15-30 parts of an oyster meat extract, 1-5 parts of a dried toad extract, 1-5 parts of plantago depressa willd, 0.01-0.05 part of nerium indicum, 10-25 parts of Chinese magnoliavine fruits, 10-30 parts of turmeric, 5-15 parts of rhizoma ligustici wallichii, 10-20 parts of radix angelicae sinensis and 10-20 parts of Chinese wolfberry fruits. The feed additive composition disclosed by the invention is suitable for seawater fish, and can effectively promote the recovery of the seawater fish after stress.

Description

technical field [0001] The invention relates to a feed additive, in particular to a seawater fish feed additive composition and its application. Background technique [0002] With the continuous maturity of land-based aquaculture technology, the mariculture industry has entered a period of rapid development. However, due to the impact of natural disasters such as high-density farming, drug abuse, pollution of offshore waters, changes in seawater salinity, and typhoons, seawater cultured fish are in a state of physiological stress for a long time, resulting in slow growth, decreased immunity, and frequent disease outbreaks. Seriously hindered the healthy development of seawater aquaculture. In order to ensure the sustainability of the mariculture industry, finding ways to eliminate or alleviate the impact of environmental stress has become a major problem that needs to be solved urgently. [0003] After environmental stress (such as crowding, hypoxia, ammonia nitrogen, heav...
