Example Embodiment

[0025] The preparation method of the chitin of the present invention is as follows: take a certain amount of fresh lobster shells, clean water to remove foreign matter on the inner and outer surfaces of the shells, dry them in a constant temperature blast drying box at 105°C for 4 hours, and crush them through a 40-mesh sieve. Then soak in 1.0mol / l hydrochloric acid solution at room temperature for 18h, the ratio of shrimp shell to hydrochloric acid solution is 1:8 (w / v), filter, the filter residue is rinsed with industrial water to neutrality, and then the filter residue is soaked in 2mol at room temperature / l Sodium hydroxide aqueous solution for 18h, the ratio of shrimp shell to sodium hydroxide solution is 1:8 (w / v), filter, rinse the filter residue with water to neutral, then use 10% hydrogen peroxide in the 80℃ water bath Soak for 2h to decolorize, wash with water and dry to obtain chitin.

Abstract

The invention relates to a feed additive for broiler chickens and a preparation method of the feed additive, belonging to the field of feed additives. The feed additive comprises the following materials based on parts by weight: 35-38 parts of chitosan, 35-38 parts of chitin, 12-15 parts of calcium amino acid chelate, 2-3 parts of zinc amino acid chelate, 2-3 parts of iron chitosan chelate, 1-2 parts of copper chitosan chelate and 5-7 parts of D-glucosamine hydrochloride. The feed additive is obtained by means of conventionally drying, mixing, crushing, sifting, physical blending and packaging the above materials. The feed additive for broiler chickens is applied after being mixed with the daily ration of animals, and the addition amount is 1.5% of the total amount of the daily ration. The use of the feed additive can effectively promote animal growth, enhance organism immunity and reduce fat content and cholesterol content of the broiler chickens, and the feed additive can partly or completely replace antibiotics in the daily ration.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive for livestock and poultry feed. Background technique [0002] The safety of livestock and poultry products has always been the focus of consumers. The development and application of green feed additives, health medicines, disinfectants, etc. in all aspects of livestock and poultry breeding and production can effectively solve the problem of drug residues, reduce the use of antibiotics in the process of livestock and poultry feeding, improve the meat quality of livestock and poultry, and enhance the quality of animal sources. Sexual food safety. The research on the application of chitin, chitosan and their derivatives in animal health care and animal nutrition shows that they have obvious physiological functions, such as improving the body's immunity, broad-spectrum antibacterial, lipid-lowering and cholesterol-lowering effects, and promoting wound healing , Preven...
