Canthaxanthine is an important carotenoid that widely exists in organisms in nature. Because of its good coloring effect and high stability, it is often used as a colorant in food, feed, cosmetics, etc. Its application examples are as follows:
1) Prepare the coloring agent in the pelleted feed for large-scale three-yellow chickens, and calculate the total content of lutein and total content of Canthaxanthine required in the feed according to the expected coloration table of the legs of three-yellow chickens, and calculate the total content of lutein by measuring the content of lutein in the base material The content of natural lutein and cantharidin that needs to be added is premixed with natural lutein, cantharidin and low-gluten flour to form a lutein premix, and the lutein premix is added to the base material to provide a The invention discloses a method for adding a coloring agent in the pellet feed of fast and large-scale three-yellow chickens, which has strong operability and can precisely control the chromaticity of three-yellow chicken legs.
2) Prepare a feed additive premix. The feed additive is composed of the following raw materials in parts by weight: 150-450 parts of astaxanthin, 300-700 parts of Dunaliella salina, 150-400 parts of vitamin E, 300-600 parts of Bupleurum, 100-250 parts of Canthaxanthine, 300-600 parts of oxidizing agent, 150-1000 parts of corn gluten powder. The invention has no toxicity, side effects, drug resistance, environmental protection, and no adverse effect on the palatability of the feed; it can obviously improve the quality of yellow and red color fish such as golden pomfret, yellow catfish, pond louse, red sea bream, and large yellow croaker. Body color, making the body color appear natural yellow or red; and can effectively improve the immunity, reproductive ability and meat quality of farmed fish; and its raw material source is stable, and the production process is simple.
3) Prepare a chicken astaxanthin life element, its formula (by weight percentage) DL? Methionine 1.9-2.9%, L? Sodium Ascorbate 1.6-2.6%, potassium dihydrogen phosphate 2.3-3.3%, Pediococcus lactis 2.5- 3.5%, Calcium Acetate 2.1-3.1%, Ingot Oil Extract 2.8-3.8%, Rhodopseudomonas Viridans 0.9-1.9%, Guar Gum 0.6-1.6%, Dandelion Root Extract 1.5-2.5%, Brevibacillus 1.9 -2.9%, Asarum 1.1-2.1%, Glucose Oxidase 1.6-2.6%, Ligusticum 1.7-2.5%, Canthaxanthine 1.5-2.3%, Xanthium 1.3-2.2%, Vitex 1.8-2.8%, Dimethyl Pyrimidinol menadione sulfite 1.9-2.9%, Bacillus lentus 2.7-3.7%, manganese carbonate 0.3-1.3%, snake gallbladder extract 0.8-1.8%, astaxanthin 0.1-1.1%, water 67.1-46.6%. The invention has the advantages of significantly enhancing the muscle strength and tolerance of chickens, greatly improving the survival rate in a stressful environment, promoting the production of antibodies and reducing the mortality of chickens.
