Biological feed for improving nutrition density and flavor of eggs and preparation method of biological feed

Abstract

The invention relates to the technical field of animal feeds, in particular to a biological feed for improving the nutrition density and flavor of eggs and a preparation method thereof. Aiming at the problems of insufficient nutrition density, single flavor and low resource utilization rate of the traditional feed, the invention realizes the purposes of improving the nutrition density, remarkably increasing the contents of nutrients such as DHA, selenium and vitamin E in eggs and improving the flavor by scientifically proportioning functional components and optimizing a preparation process, reducing the fishy smell of the eggs and improving the crispy mouth feel and color of the eggs. Agricultural wastes (such as tenebrio molitor dung and lobster shell powder) are utilized to reduce the production cost, the content of DHA and selenium in eggs is increased through multi-dimensional nutrition enhancement, the flavor is improved by utilizing dried orange peel powder and capsanthin, and resource utilization of wastes such as the tenebrio molitor dung is realized.

Description

Technical Field

[0001] This invention relates to the field of animal feed technology, and in particular to a biological feed that enhances the nutritional density and flavor of eggs and its preparation method. Background Technology

[0002] As consumers become increasingly concerned about food safety and nutritional value, the market demand for high-quality eggs is growing. While traditional laying hen feed can meet basic egg production needs, it has the following problems:

[0003] Insufficient nutrient density: Ordinary feeds are unlikely to effectively increase the content of key nutrients such as DHA, selenium, and vitamins in eggs.

[0004] Monotonous flavor: The flavor of eggs is significantly affected by feed composition. Traditional feeds tend to result in eggs with a strong fishy smell and poor taste.

[0005] Low resource utilization: A large amount of agricultural waste (such as mealworm excrement and sugarcane bagasse) is not fully utilized.

[0006] In the prior art, patent CN1186615A discloses a biological compound feed that improves feed utilization by adding enzymes and lactic acid bacteria, but it does not optimize for the nutrition and flavor of eggs; patent CN104351500A involves feed that improves the flavor of eggs, but its functional components are relatively simple and it does not solve the problem of improving nutrient density. Therefore, developing a biological feed that combines nutritional fortification and flavor improvement is of great practical significance. Summary of the Invention
