The invention relates to the technical field of aquaculture feed, in particular to a feed additive for improving ovary color of scylla paramamosain and application of the feed additive. The feed additive is prepared from the following raw material components in parts by mass: 30-60 parts of Chinese wolfberry fruit powder, 10-30 parts of a marigold extract, 2-8 parts of chenodeoxycholic acid and 5-15 parts of vitamin E powder. The additive systematically solves the technical bottlenecks of low absorptivity and unstable deposition of natural pigments in crab bodies through the synergistic effect of all the components. When the feed additive is added into feed for fattening female scylla paramamosain, the ovary redness value can be remarkably increased, the color is rich and natural, and meanwhile, the growth of parent crabs and the development of gonad are promoted. The feed is completely prepared from natural raw materials, is safe, free of residues and controllable in cost, and provides an effective scheme for realizing high-valued and green cultivation of scylla paramamosain'red cream crab '.

This invention discloses a method for preparing fat-soluble vitamin E powder. The specific operation process is as follows: after preparing a powdered drug cocrystal product using ball milling, a more efficient, green, and sustainable mechanochemical method is employed to improve the preparation process, resulting in better uniform dispersion of the drug and carrier. Solubility is used as the evaluation target to screen vitamin E inclusion materials and excipients, and the optimal formulation is selected for preparing the vitamin E cocrystal inclusion complex. Results show that the method of this invention effectively improves the solubility and other physicochemical properties of fat-soluble vitamin E. Its low energy consumption and minimal use of toxic and harmful reagents give it multiple advantages for large-scale production. Therefore, it has broad application potential and is of great significance for the formulation of vitamin drugs.

The application discloses a chicken feed additive rich in DHA and having liver protection function, and a preparation method and application thereof. The chicken feed additive contains the following components in parts by weight: 40-60 parts of double-source DHA reinforcing component, 20-30 parts of plant synergistic liver protection component, and 5-10 parts of microecological and metabolic regulator. The double-source DHA reinforcing component is compounded from compound DHA microcapsules and squid egg powder. The plant synergistic liver protection component is a compound product formed by synergistic fermentation of sea buckthorn seed meal, spilanthes acmella and pineapple residue by bacillus natto. The microecological and metabolic regulator contains bacillus natto powder, vitamin E powder and tea polyphenol powder. The DHA content of the chicken eggs produced by the method can reach 250 mg / 100 g or more, and the proportion of phospholipid type DHA in the total DHA is greater than or equal to 35%. Meanwhile, the liver function of the laying hens is normal, the liver index and fat deposition rate are maintained in the normal physiological range, and the body health of the laying hens is effectively ensured.

The invention provides oral oxytocic hormone feed for parent fish of wild sal-family pseudosciaena crocea as well as a preparation method and application of the oral oxytocic hormone feed, and belongs to the technical field of breeding of the wild sal-family pseudosciaena crocea. According to the oral oxytocin feed for the parent fish of the wild sal-family large yellow croaker, provided by the invention, a high-protein floating compound feed is taken as a carrier, and a gonadotropin releasing hormone analogue GnRH-a, a dopamine receptor antagonist DOM, vitamin E powder, immune polysaccharide for fish and seaweed meal are added. The invention further provides a preparation method and application of the oral oxytocic hormone feed for the parent fish of the wild sal-ammoniac pseudosciaena crocea, and provides an oxytocic, insemination and artificial propagation method for the wild sal-ammoniac pseudosciaena crocea, so that the propagation success rate and the fry quality of the wild sal-ammoniac pseudosciaena crocea are remarkably improved; the technical bottlenecks of stress sensitivity, asynchronous oviposition, unstable egg quality and the like of wild parent fish are overcome, and the method has remarkable popularization value and industrial application prospect.

The invention relates to the technical field of feed additives, in particular to a mixed feed additive for beef cattle fattening and a preparation method thereof. The preparation method comprises the following steps: firstly, mixing hydrogenated palm oil, palm oil, ethyl acetate and tea polyphenol, heating until the mixture is completely melted, then spraying the mixture onto the surface of granular urea to obtain palm oil-based coated urea, and then preparing a chitosan-based coating solution by inclusion of beta-cyclodextrin with vitamin E powder and O 'O-lauroyl chitosan; and finally, coating the surface of the palm oil-based coated urea by using glutaraldehyde as a cross-linking agent to form the mixed feed additive for fattening beef cattle. The prepared mixed feed additive is balanced in nutrition, nitrogen source slow release can be achieved, and the meat percentage of beef cattle is effectively increased.
