  　　Factory Directly Offer Feed Grade Natural Astaxanthin in Stock

  　　Product Description:  Astaxanthin is a powerful antioxidant found in shrimp and other crustaceans. It has numerous beneficial effects, making it a valuable component in animal feed.

  　　Key Benefits:

  　　1. Rich in Natural Astaxanthin: Astaxanthin is a potent antioxidant, approximately 6,000 times stronger than vitamin C. It quickly enhances the vitality of shrimp and crabs, with noticeable effects in 1-2 days.

  　　2. Neutralizes Harmful Free Radicals: Astaxanthin effectively combats various environmental stress factors like temperature fluctuations, algal blooms, high temperatures, and heavy rainfall, which can otherwise lead to stress-related diseases.

  　　3. Improves Pigmentation: Astaxanthin rapidly accumulates in aquatic animals, enhancing their coloration. It provides a noticeable "brightening" effect, making farmed animals closer in appearance to their wild counterparts, thereby increasing their market value.

  　　4. Boosts Immune Function: Astaxanthin promotes the production of immunoglobulins (IgG, IgA, IgM), significantly elevating immune function.

  　　5. Rich in Nucleotides: This pigment is rich in yeast nucleotides, known for their strong appetite-stimulating effects, which accelerates food intake.

  　　6. Nutrient-Rich: Astaxanthin contains essential nutrients such as vitamin A, vitamin D, and carotenoids, which promote nutritional balance, enhance calcium and phosphorus absorption, and significantly improve the survival rate and uniformity of seedlings.

  　　Usage and Dosage:

  　　Applicable Objects: All kinds of farmed animals and aquaculture waters, including South American white shrimp, river crabs, crayfish, and various farmed aquatic animals in the seedling and grow-out stages.

  　　1. For shrimp and crabs: Mix 500-1000 grams of the product per ton of feed, continuously use for 7-15 days, or for an extended period.

  　　2. For fish such as Epinephelus coioides: Double the dosage.

  　　3. For fish, shrimp, and crab before marketing, use 2 kg per ton for 7 consecutive days to significantly reduce stress during harvesting and improve transportation survival rates.

  　　Notes:

  　　1.This product is not water-soluble, so pre-mixing is required for addition.

  　　2.It is heat-resistant and can be directly added to extruded feed.

  　　3.Being liposoluble, it is more effective when pre-dissolved in feed oil or fat.

  　　4.Keep the product sealed, protected from light, and stored below 22°C.

  　　Usage in Aquatic Animal Feeding:

  　　·For juvenile shrimp: Add 0.4-0.8 kg per ton of feed (50% increased survival rate); throughout the entire culture period.

  　　·For mature shrimp: Add 0.24 kg per ton of feed (45% increased survival rate, significant reduction in shrimp disease); two months before harvesting.

  　　·For broodstock shrimp: Add 0.75-1.5 kg per ton of feed (40% increased spawning); two days before spawning.

  　　For Poultry and Egg Production:

  　　·Add 0.4-0.6 kg per ton of feed during egg production (starts from day 7, duck eggs can reach grade 16); used for the entire egg production period.

  　　For Trout Farming:

  　　·Add 2.5-5 kg per ton of feed (50% increased survival rate); during the 8-12 weeks before harvesting.

  　　For Shrimp Farming:

  　　·For juveniles: Add 0.4-0.8 kg per ton of feed (50% increased survival rate); throughout the entire culture period.

  　　·For mature shrimp: Add 0.24 kg per ton of feed (45% increased survival rate, significantly reduces shrimp diseases); two months before harvesting.

  　　·For broodstock shrimp: Add 0.75-1.5 kg per ton of feed (40% increased spawning); two days before spawning.

  　　Note:

  　　·Do not come into contact with oxidizing agents.

  　　·Use the product immediately after opening.

  　　·Ensure feed contains vitamin E or mycotoxin-binding agents.

  　　·It is best to store the feed in a sealed, light-protected, and cool place, below 22°C.
