Description

Feed premix and application thereof

Technical Field

The invention relates to the technical field of feed processing, in particular to a feed premix and application thereof.

Background

In recent years, the livestock and poultry breeding industry in China is gradually enlarged in scale and gradually improved in strength. The key basic part is feed, the feed additives are various in types, and most of the feed supplements related products with amino acids, minerals, vitamins and the like, but in the prior art, the added components are mostly chemical synthetic preparations or inorganic salts of trace elements, so that the utilization rate of animals is low in the process of digestion and absorption, and the animals are poisoned by excessive amounts. Feed additives of natural plant origin are the direction of development in the future.

The microalgae is rich in polyunsaturated fatty acid, protein, carotenoid, vitamins and various minerals, can improve omega-3 unsaturated fatty acid, vitamins and minerals in animal products, and becomes a good feed additive. Especially, Haematococcus pluvialis contains astaxanthin which has a coloring function and is the most potent antioxidant found so far, and plays an important role in improving the quality of eggs. However, the direct addition of microalgae into the feed has the disadvantages of difficult uniform stirring, relatively single function and the like.

No report is provided on laying hen feed which comprehensively utilizes the advantages of haematococcus pluvialis and other feed additives, can mutually cooperate and promote each other, obviously improves the contents of unsaturated fatty acid, vitamin B12 and pantothenic acid in eggs, can improve the color of egg yolk and achieves the purposes of comprehensive nutrition and yield improvement.
