Problems solved by technology

[0004] However, due to the wide variety of microalgae and the rich nutritional components of various algae, how to comprehensively utilize the advantages of various algae, when the algae are used as feed additives, can make them cooperate and promote each other, and at the same time significantly improve the egg content. Unsaturated fatty acids, vitamin B 12 and pantothenic acid content, and can improve the color of the egg yolk, to achieve the purpose of comprehensive nutrition and increase production of laying hen feed has not been reported

Abstract

The invention relates to the technical field of feeds, and especially relates to a laying hen feed additive, a laying hen feed, and a preparation method of the laying hen feed. By comprehensively utilizing advantages of various kinds of algae, the contents of unsaturated fatty acid, vitamin B12 and pantothenic acid in eggs are significantly increased, the content of cholesterol is reduced, color of yolk is improved, and immunity and egg yield of laying hens are raised; and thus, the goals of comprehensive nutrients and increased yield are achieved. An embodiment of the invention provides a laying hen feed additive, wherein the laying hen feed additive is algae powder; and the algae powder is prepared by mixing schizochytrium, chlorella and nannochloropsis sp. or residues thereof. The embodiment of the invention is used for preparing a laying hen feed.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed additive for laying hens, a feed for laying hens and a preparation method thereof. Background technique [0002] In recent years, my country's livestock and poultry breeding industry has developed greatly. There are many kinds of feed additives. Most of them provide amino acids, minerals and vitamins to supplement the nutrition of animals and animal products. However, most of the ingredients added in the prior art are Chemical synthesis preparations or inorganic salts of trace elements, on the one hand, the utilization rate of animals is low in the process of digestion and absorption, and on the other hand, excessive amounts will cause animal poisoning. [0003] Because microalgae are rich in polyunsaturated fatty acids, proteins, carotenoids, vitamins and various minerals, they can increase the omega-3 unsaturated fatty acids, vitamins and minerals in animal products, and bec...
