Problems solved by technology

[0004] At present, relevant scholars at home and abroad have done some research and development work on increasing the DHA content in eggs. Most of them use substances with high DHA content in the feed, so that the laying hens can enrich the DHA in the feed into the eggs. However, the existing The method of technically producing eggs with high DHA content will easily lead to limited enrichment of DHA and large addition of oil components, resulting in increased mortality of laying hens and increased cholesterol content in eggs. Moreover, DHA has a high degree of unsaturation and is easily oxidized in vivo and in vitro. Thereby affecting egg quality and mouthfeel local flavor, prior art does not carry out research on above-mentioned technical problem

Abstract

The invention provides a laying hen feed additive, which is composed of the following raw materials by weight percentage: 56.4% to 69.3% of Chinese prickly ash seed, 30% to 40% of Schizochytrium Limacinum powder, 0.25% to 1.5% of Haematococcus pluvialis powder, 0.25-1.5% of lipase, and 0.2% to 0.6% of a L-selenomethionine preparation. The obtained product is added to a laying hen feed in a ratio of 2 to 4 wt%, and the materials are mixed uniformly for feeding. The Chinese prickly ash seed, Schizochytrium Limacinum powder, Haematococcus pluvialis powder, lipase and L-selenomethionine are combined to prepare the feed additive of the laying hen, the feed additive can significantly improve the enrichment rate of DHA in the egg and can also significantly improve the egg quality, and reduces thecholesterol content of the egg. The feed additive of the invention has obvious effect, and the lower omega-3 polyunsaturated fatty acid raw material can achieve higher egg DHA enrichment, and the eggproduction rate is not reduced, and the economic benefits can be increased.

Description

technical field [0001] The invention belongs to the technical field of feed industry and relates to an animal feed additive, in particular to a laying hen feed additive and a use method thereof. Background technique [0002] Docosahexaenoic acid (DHA) is an essential nutrient for human growth and development, and is an important component of the brain and retina, and DHA has the effect of lowering blood lipids, and can also form anticoagulant factors to avoid the formation of thrombus and prevent Atherosclerosis, myocardial infarction, reduce the incidence of coronary heart disease. DHA mainly exists in marine organisms such as deep-sea fish and seaweed. Most residents in my country do not have enough food intake of DHA. Although the human liver can partially synthesize DHA from α-linolenic acid (ALA), the synthesis efficiency is relatively low. Low, while laying hens can enrich ALA and DHA in the plant raw materials in eggs, and laying hens can also convert ALA into DHA and...
